[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

>From what I can tell the maintainers have no intention of spending time
supporting Ubuntu 16.04 or older. Even when Xenial was the current LTS
they weren't responding here, and now that 18.04 has been out for 5
month there's even less motivation to handle older distros.

Having built Firefox 59 from source I think I get some of the reasons
why they'd consider this a heavy support task. It's hard to get gcc and
Rust to play nice on old cross-compiling toolchains, not to mention that
sketchy assembly code for XPCOM. From a practical perspective, user
workarounds can go in this order:

1) Use the latest firefox:armhf on 18.04 Bionic, if that's what you're
running or you're open to upgrading.

2) Earlier distros like 16.04 or Debian Stretch: Install the latest
firefox:arm64 if your system supports AArch64.

3) If armhf is the only option and you're on 16.04, you can still set up
the firefox 18.04 deb package from Launchpad. Download its dependencies
like libstdc++ and following my instructions in #117 to place the
appropriate runtime-linked libraries.

Relying on armhf builds from Bionic in the worst case 3): this avoids
having someone to maintain the whole build flow for Xenial and Trusty.

I'm only speaking for Firefox here, but if it all comes down to crashes
in libxul.so then maybe much of this is sufficient for Thunderbird too.

[James Donald]

Lars, I went to sites like Gmail or Youtube that I thought had a chance
of using optional NaCl, but I haven't been able to reproduce those error
messages. I don't think Firefox supports NaCl, even with a plugin. Is it
possible you imported browser settings from Chromium and it happened to
include their NaCl extension? You could rule this out by moving or
deleting ~/.mozilla/firefox then trying again.

herrtimson, an illegal instruction would indicate your system lacks NEON
or ARMv7 altogether, the same reason Firefox does not run on ARMv6
boards like Raspberry Pi B+ or Pi Zero. To check, cat /proc/cpuinfo

There's also a chance that ungültiger maschienenbefehl means bad
interpreter or not in executable format / File format not recognized.
You can troubleshoot this with the ldd and file commands. Compare
properties of /usr/lib/firefox/firefox to any working command under
/usr/bin

> Oh, and how do I revert this to the ubuntu one? *_*

sudo apt-get purge firefox
sudo apt-get install firefox

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

@herrtimson I looked in the tarball and don't even see mention of my use
of clang in mozconfig.

Note I'm using a procedure similar to what Chituc outlined. If I kick
off dpkg-buildpackage, interrupt it, then edit the generated backend.mk
I would not expect that to appear in patch files. It's also possible
that due to use of the -b flag it skips version control comparisons, so
the C++ source diffs are not appearing either.

For now I have documented pieces manually in this repo:
https://github.com/jdonald/firefox-armhf

I'll update that repo as more steps come to mind.
firefox_59.0.2.build1-0ubuntu0.14.04.4.debian.tar.xz is available for
download there in the releases tab if you'd like to take a look through
it.

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

@herrtimson

Here's a 14.04 Trusty build:
https://www.dropbox.com/s/977vzb3mu8bf34z/firefox_59.0.2%2Bbuild1-0ubuntu0.14.04.4_armhf.deb?dl=0

I used the same approach with clang + gcc headers inside a Trusty
(gcc-4.8) container. Initially I got errors about ::gets() and Stack
Overflow sent me down some rabbit holes of attempting to use gcc-4.9
headers or libc++ armhf. Ultimately the workaround was to comment out
the offending line in gcc headers, and also fix a constexpr bug in the
 header. These kinds of hacks are something one can be more
comfortable doing inside a Docker container.

I don't have a 14.04 armhf setup but I did test this on Raspbian
Stretch. Would be great if you could try it out on your system. Note
initially it used up all my Pi's RAM so I had to add 1 GB of swap.

For others, here is a 16.04 Xenial build:
https://www.dropbox.com/s/ogdut56m2i0k0t9/firefox_59.0.2%2Bbuild1-0ubuntu0.16.04.3_armhf.deb?dl=0

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

@herrtimson from my tests that patch does not resolve the strd r2, r3,
[r1] crash on Xenial. However, I do believe it's entirely possible that
it indirectly fixed the issue with your gcc-7 toolchain. I'm starting to
wonder if this crash does not have a single cause but rather is a
codepath that Firefox goes down if there is one of many possible
failures in startup.

In addition to the Bionic build above, this weekend I got a Raspbian
Stretch build working:
https://www.dropbox.com/s/sdqwuda5eaw0cks/firefox_59.0.2%2Bbuild1
-stretch-rpi2_armhf.deb?dl=0 with some overview on the forums:
https://www.raspberrypi.org/forums/viewtopic.php?f=63=150438

I used Bionic sources (deb-src http://ports.ubuntu.com/ubuntu-ports/
bionic main restricted) in a Stretch container (gcc-6). Initially it
crashed on the same strd, so I tried switching to clang and then
encountered the same "undefined reference to `free'" errors you guys had
mentioned. These come about mainly due it not being supported to call
free() before declaration in C99, so then the fix was to add #include
 in a couple places.

I don't think I'll attempt another Xenial or Trusty build anytime soon.
I'd like to get some fixes documented and patches submitted upstream so
that others can start building Firefox armhf across more platforms.
Anyone can still run the 18.04 binary I linked earlier on 16.04 (and
possibly 14.04) using the LD_PRELOAD trick.

As for how Arch Linux has been working, I've confirmed it's due to
--disable-stylo (mentioned a while ago on the Raspberry Pi forum
thread). If I add that flag (while leaving SK_JUMPER_USE_ASSEMBLY
intact) then Firefox runs. For some reason the Stylo flag does not get
listed in about:buildconfig but it's a very different build path when
MOZ_STYLO is disabled, and Stylo is still disabled for Android nightly
too.

[James Donald]

@herrtimson are you expecting revert-128661.patch to fix the strd r2,
r3, [r1] startup segfault on xenial/trusty, the Skia assembly illegal
instruction, or both?

The discussion in bug 1434526 indicates this patch is necessary on
Firefox 60 to resolve an armhf build failure on the latest trunk, but
that regression appears to be newer than both of the crash symptoms at
hand here.

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

Here is a working Firefox 59 deb package cross-compiled for 18.04 armhf:
https://www.dropbox.com/s/17ypog6btdq4wj7/firefox_59.0.1%2Bbuild1-0ubuntu1_armhf.deb?dl=0

I have installed and tested on RaspEX (Bionic armhf). I can also confirm
it works sandboxed on Ubuntu MATE Xenial and Raspbian Stretch. One way
to run on older systems is to unpack locally using ar + tar, download
libc6 and libstdc++6 bionic armhf debfiles and untar them as well, then
do:

  cd path/to/usr/lib/firefox
  
LD_PRELOAD=path/to/usr/lib/arm-linux-gnueabihf/libstdc++.so.6:path/to/lib/arm-linux-gnueabihf/libm.so.6
 \
./firefox

Cross-compiling via dpkg-buildpackage is fraught of issues, and similar
to what Chituc experienced the most difficult part was getting rustc to
properly cross-compile in all cases. I posted my main workaround for a
host/target header bug here: https://github.com/rust-lang-nursery/rust-
bindgen/issues/1229

To prevent the Skia misaligned instruction crash, I ended up editing
gfx/skia/generate_mozbuild.py to force SK_JUMPER_USE_ASSEMBLY to False.
However, there's stubborn code at the top of SkJumper.cpp that ends up
turning it on again so I had to override that too. Telling Skia to use
its non-asm fallback mode should be better than disabling Skia
altogether as we had for Firefox 57.

I tested some of our earlier theories too, and so far building Skia with
clang, everything with -thumb, -fstack-protector-strong, --enable-rust-
simd or other suggestions above do not seem to help at all with the Skia
SIGILL nor the strd r2, r3, [r1] SIGSEGV.

As for that strd r2, r3, [r1] crash, not much progress there aside from
our theory that it's in the XPCOM armhf-specific code. I'm merely
avoiding it by building in a 18.04 Docker container, but still no idea
why that works.

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

@levente (and maybe @herrtimson),

I set up a new Ubuntu MATE system, and in the process realized that your
segfault in /lib/ld-linux-armhf.so.3 is a symptom of bug 1576432. That's
where gdb fails not only for Firefox but even a simple helloworld
program. The workaround there is to install libc6-dbg, which will allow
you to see one of the other two crash signatures that we still don't
have a solution for.

@Chituc,

By waiting a couple days on my Pi 3 I managed to make a gcc-4.9 build of
Firefox 59.0.1, which then crashes on strd r2, r3, [r1]. I'm now
thinking that this startup crash may be more nuanced than being specific
to Ubuntu 16.04 or gcc-5.4. In fact, the Launchpad builds are now
showing something odd: While the 59.0.1 14.04 build that we've talked
about gets all the way to the Skia SIGILL, the recent 59.0.2 14.04 build
from
https://launchpad.net/ubuntu/trusty/armhf/firefox/59.0.2+build1-0ubuntu0.14.04.1
segfaults on the strd too.

At least with a custom build I'm now able to get accurate debug symbols.
With the TUI I inspected the source at each level of this stack trace:

#0  0x717c4bc8 in JS::Value::setObjectNoCheck (obj=0x67d62160, this=) at

#6  0x001e in ?? ()

(and ran disas /r 0x717c4bc8,... to confirm that this symbol-laden debug
session was still hitting strd r2, r3, [r1])

The most suspicious code is actually the XPCOM invocation. The armhf-
specific assembly in https://hg.mozilla.org/mozilla-central/raw-
file/tip/xpcom/reflect/xptcall/md/unix/xptcinvoke_arm.cpp is worrisome.
It has no way of knowing whether registers d16 through d31 are
available, so may allocate the wrong amount of stack space and clobber
extra registers when mixing -mfpu=vfpv3-d16 with -mfpu=neon. The code in
xptcinvoke_aarch64.cpp is completely different and looks more robust.

Thus, if anyone is trying to set up a build environment on Ubuntu 14.04
Trusty, keep in mind you might still hit the strd r2, r3, [r1] SIGSEGV.
On Bionic: the 59.0.1 18.04 build from Launchpad was okay in this
regard, while the 59.0.2 18.04 build hasn't been posted yet so fingers
crossed that it does not regress in the same way.

Thanks @Chris!

@herrtimson you can do this:
  layout asm
  tui disable
  set logging on
  disas /r ,

It'll save the output of your disas command to gdb.txt

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

@herrtimson we already confirmed that the gcc-7 / Bionic build crashes
on the exact same misaligned instruction in Skia. See responses #48 and
#50 for how I tested this, the point being that waiting for Bionic alone
won't fix this.

Diagnosing a corrupt stack: whether you have debug symbols or not you
should run this in gdb: layout asm. This will tell you if it's the same
Skia illegal/misaligned instruction, the earlier SIGSEGV crash at strd
r2, r3, [r1], or something else. Because levente was using a 16.04 deb
he was most likely hitting the known SIGSEGV. Would be good to identify
your build's crash because we don't have any other datapoints for gcc 6.

[James Donald]

@Chituc,

I attempted to set up an Ubuntu 14.04 Firefox build environment, and am
realizing how difficult it is to troubleshoot something old and barely
supported.

Instead, could you take your existing 16.04 build flow but run sudo apt
install g++-4.8 then build with CC=gcc-4.8, CXX=g++-4.8?

There's a decent chance this will get you past the strd r2, r3, [r1]
crash, which would then allow you to complete your test of the clang
Skia theory.

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

Ugh, yeah doing some simple helloworld tests confirms these are armhf
gcc *defaults*.

> it's what *defines* armhf as armhf.

Defines: This appears true for -march=armv7-a -mfloat-abi=hard. As for
-mfpu, adding -mfpu=neon results in some assembly differences, namely
using register d16 and above.

> Unless something is explicitly setting those things differently

The Firefox build log has some instances of -mfpu=neon, particularly in
Skia. However, Chromium does as well so indeed this is a longshot.

Looks like we're back to the drawing board. Still some hope with changes
like building Skia using clang, adding -mthumb, or -fstack-protector-
strong, but none of these other differences stand out as something
present in both the Chromium and Arch Linux builds.

I think I misunderstood earlier about the intent of looking at Firefox
57's about:buildconfig. As that's technically still a Skia-broken build,
we can continue to examine that configuration for other differences vs
the Arch Linux one.

> [herrtimson] If there's a chance to get the output of
about:buildconfig regardless the segfault at startup, I'm all eager to
learn about this.

With broken browsers like Firefox 58 and 59 armhf, find the build config
like so:

strings /usr/lib/firefox/omni.ja | grep -A 31 "Built from"

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

> [herrtimson] I wrote an email to Chris Coulson, asking for some
assistance with the cflags. Hopefully he'll read it.

Thanks. I flagged him on #ubuntu-devel IRC as well. Hopefully we'll get
his attention this time.

> > [Chituc] Can you check if the firefox 57.04 trusty , the working one shows
"-march=armv7-a -mfloat-abi=hard -mfpu=vfpv3-d16" in about:buildconfig ?
> [Chris] It’s not showing those flags in about:buildconfig

I don't think this matters, because Firefox 57 Trusty still has the Skia
crash for most armhf users. The main difference between Firefox 57 and
58/59 is that in Firefox 57 it's possible to disable Skia via prefs.js,
but otherwise the misaligned instruction bug is still there.

> it fixes freebsd only, but still it might be helpfull to see what they
changed.

The majority of that patch deals with atomics, compare-and-swap, and
memory barriers, although might be worth noticing that it does add
-march=armv7-a

> [Chituc] Builing on xenial did nto worked but a build in trusty have
great chances to work .

Right, but important to note that building on Bionic will likely work
too. That point may be helpful in getting the Ubuntu team to prioritize.

> CFLAGS="-march=armv7-a -mfloat-abi=hard -mfpu=vfpv3-d16"

In case anyone is testing this soon, be sure to set both CFLAGS and
CXXFLAGS. SkJumper_generated.S is assembly and I'm not sure which of the
two flag sets gets passed, but the Skia project is largely C++.

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

Awesome, thanks for confirming Arch still works and posting the
screenshot.

> Also anyone tried to run the binary from bionic, which should be built
with gcc-7 as well?

Yes, Lars and I both tried this. It's rather buried in discussion above
but search for the part where I mention "ignore the dependency" in order
to test the gcc 7 Bionic build on a Xenial system.

> --enable-rust-simd caught eye, what is this all about?

There are Rust bindings for Skia, but the part where it crashes doesn't
use Rust. From your screenshot I think these are likely the key missing
flags: -march=armv7-a -mfloat-abi=hard -mfpu=vfpv3-d16

In the conversation above, those are exactly the flags we suspected from
comparing the Chromium build. Looks like we don't actually need clang,
and we don't need -mthumb

Well, there's still the other startup crash specific to Ubuntu 16.04
packages. Given we don't hit it on the Bionic nor Trusty builds, that
problem is likely specific to gcc 5.4

Now we just need someone with access to change the default build
settings on Launchpad.

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

I think we just have the IRC logs that Chituc posted, no bug id.

When I searched https://bugs.chromium.org/p/skia/issues/list last months
for issues with the keyword "armhf" I did not find any such bug filed.

At the time I was about to file a ticket myself, but that made me first
run through the thought process of what their initial response might be.
Imagining that to be "well, it works for Chromium" is what inspired me
to look more closely at the chromium-browser build logs.

[James Donald]

> By the way I managed to set up a cross compile development

That's great news. Could you post your instructions? This would allow
others here to help out, considering most of us don't have ARM boards
with much RAM or 20 hours of patience.

This also opens up the possibility of making a build on Debian 9 to
match up better with Raspbian Stretch, rather than having to resort to
14.04 binaries there.

> Ok so in firefox 58.02 we have 2 bugs , this one "RootingAPI.h:580"
and the _sk_xor__vfp4 that I hope to get fixed by compiling with clang .

It appears that way, although worth noting that the crash at startup
also happens in Firefox 57, specific to the 16.04 build. You can check
that out by doing wget
http://launchpadlibrarian.net/352606050/firefox_57.0.4+build1-0ubuntu0.16.04.1_armhf.deb
and running it.

> You sugest me to get the firefox 58 from ubuntu 14 ?

Yeah, it appears to get around the crash at startup (before any window
appears, and thus before the SkJumper part) it might be necessary to
build under Ubuntu 14.04 toolchains (gcc 4.8, libc 2.19).

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

There was a typo in my above post, should say javascript.enabled, but
I'll assume you didn't have the extra dot when tried yesterday.

> I installed debug symbols

I just realized this makes it sound like you installed firefox-dbg,
which would give incorrect addresses because those symbols are for the
public apt binary. Do you mean that you *rebuilt* with debug symbols
(-g)?

> Can you check where that "crashes obscurely elsewhere" crashed ?

My NOP test earlier was flawed because it did not get the program
counter back onto a 4-byte aligned instruction + switch out of Thumb
mode. The fix was to hexedit in the thumb instructions 0020; 0047 (movs
r0, #0; bx r0). With this, Firefox 58 continues further on and then
crashes here:

   0x0040517c <_start+0>:   4f f0 00 0b mov.w   r11, #0
   0x00405180 <_start+4>:   4f f0 00 0e mov.w   lr, #0
   0x00405184 <_start+8>:   02 bc   pop {r1}
   0x00405186 <_start+10>:  6a 46   mov r2, sp
   0x00405188 <_start+12>:  04 b4   push{r2}
   0x0040518a <_start+14>:  01 b4   push{r0}
   0x0040518c <_start+16>:  df f8 24 a0 ldr.w   r10, [pc, #36]  ; 
0x4051b4 <_start+56

Firefox 59 crashes at the same instruction sequence, although the
addresses are of course different.

Getting a backtrace with symbols: Unfortunately for me if I install
firefox-dbg, firefox -g just hangs indefinitely. I thought this was due
to the limit of 1 GB RAM on a Raspberry Pi 3, but it doesn't get any
further even if I add gigabytes of swap space or wait a while.

It's also possible that the crash you're hitting is in the neighborhood
of the other one we were avoiding on Firefox 57 by specifically
installing the 14.04 package. The 16.04 packages of 57, 58, and 59 don't
even hit the SkJumper bug, instead crashing at an earlier point on this:

=> 0xf314e830:  c1 e9 00 23 strdr2, r3, [r1]
   0xf314e834:  05 9b   ldr r3, [sp, #20]
   0xf314e836:  06 9a   ldr r2, [sp, #24]
   0xf314e838:  1a 60   str r2, [r3, #0]
   0xf314e83a:  9d f8 38 30 ldrb.w  r3, [sp, #56]   ; 0x38

Although this does not appear the same as the crash on your custom
build, interestingly in both cases the segfaulting instruction is
precisely strd r2, r3, [r1]

To confirm if you're actually getting past the SkJumper problem point,
after a few seconds the Firefox window frame should appear on the screen
before it crashes. That's the behavior on
firefox_58.0+build6-0ubuntu0.14.04.1_armhf.deb currently while
firefox_58.0.2+build1_0ubuntu0.16.04.1_armhf.deb just aborts before
getting that far.

[James Donald]

Nice work!

If you edit your prefs.js to disable JIT (javascript.options.baselinejit
= false) or try to disable JavaScript altogether (java.script.enabled =
false), does it crash at the same point?

(I would expect so as these flags have not helped much when
troubleshooting in the past, but it's still something I check whenever
seeing a backtrace with JS::)

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

That's an interesting idea. As I mentioned above chromium-browser builds
with -mthumb so it's possible this is a key flag.

Sorry to hear that Firefox does not build with clang out of the box.
Another possible approach is to build the majority of Firefox with gcc
but the Skia portion in clang. You could take a look at
https://hg.mozilla.org/mozilla-central/raw-
file/tip/gfx/skia/generate_mozbuild.py and figure out how to override
the compiler just for Skia. This would still take at least 20 hours but
you are less likely to encounter clang-specific bitrot across Firefox.

To build only libxul.so, as well as to iterate quickly when you attempt
fixes like -std=gnu89 to address specific errors, have you tried the
instructions at https://developer.mozilla.org/en-
US/docs/Mozilla/Developer_guide/Mozilla_build_FAQ#Making_builds_faster ?

Thanks for working on this. It's quite an endeavor to build Firefox from
source and we're all cheering you on.

[James Donald]

I see. You're right, the kernel is aarch64 but the compiler and build
tools are armhf. The chromium-browser build log reports the same, so
cross-compilation might not be necessary.

> If you can help with what mods are required to make it compile with
clang I can try to compile it in a armhf Ubuntu 16.04 .

According to this link (https://developer.mozilla.org/en-
US/docs/Mozilla/Developer_guide/Build_Instructions/Compiling_Firefox_With_Clang_On_Linux)
you just need to edit your mozconfig to set CC=clang and CXX=clang++. In
theory you could also test compiler flags like -mfpu=vfpv3-d16 just by
setting CFLAGS and CXXFLAGS.

Many thanks if you can try this out in your build environment.

[James Donald]

Thanks for trying that, Lars. libfontconfig 2.11 vs 2.12 should be
compatible so you could force it to ignore the dependency or run in a
sandbox dir without installing. For example: ar xv
firefox_58.0.2+build1-0ubuntu1_armhf.deb; tar xvf data.tar.xz; cd
./usr/lib/firefox; ./firefox

This gave me the idea that this could even be tested on Ubuntu MATE
16.04, so I tried that. The only other dependency I had to unpack
locally was gcc-7 libstdc++6:
https://launchpad.net/ubuntu/bionic/armhf/libstdc++6/7.3.0-1ubuntu1

Unfortunately this gcc-7 build crashes on the same misaligned
instruction, so that dashes hopes of resolving this merely with a newer
toolchain.

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

Thanks Chituc. That's spot-on with the identical error in Firefox.
Specifically, it's not an illegal instruction so much as a misaligned
(+2 bytes) instruction, plus at that point it's in Thumb mode when
anything inside SkJumper should be in ARM mode.

Technically both firefox and chromium-browser are cross-compiled because the 
Launchpad logs show the host system as aarch64 while the target is armhf:
* 
https://launchpadlibrarian.net/356307711/buildlog_ubuntu-xenial-armhf.firefox_58.0.2+build1-0ubuntu0.16.04.1_BUILDING.txt.gz
* 
https://launchpadlibrarian.net/357154172/buildlog_ubuntu-xenial-armhf.chromium-browser_64.0.3282.167-0ubuntu0.16.04.1_BUILDING.txt.gz

Chromium adds a few more flags that might affect NEON i.e. -mfloat-
abi=hard -mtune=generic-armv7-a -mfpu=vfpv3-d16 -mthumb, but as you've
pointed out the biggest difference is compiling with clang. Apparently
clang is actually supported for building Firefox on Linux, so maybe the
Launchpad script could be augmented to just add two required lines to
mozconfig.

Looks like Firefox 58 for 18.04 Bionic armhf built successfully and uses gcc 7: 
https://launchpad.net/ubuntu/+source/firefox/58.0.2+build1-0ubuntu1/+build/14326274
Anyone able to try it out?

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

Various notes:

Good point by Chituc. I had assumed this was already cross-compiled, but 
according to the Ubuntu build log:
> checking whether cross compiling... no

Who here knows how the Arch Linux armhf package is built?

It's also still possible that a newer toolchain could fix things. I read
somewhere that Ubuntu 18.04 Bionic would be upgrading to gcc 7. Anyone
tried Firefox 58 or 59 on there?

The SkJumper_generated source is available on Mercurial:
https://hg.mozilla.org/mozilla-central/raw-
file/tip/gfx/skia/skia/src/jumper/SkJumper_generated.S

It's possible to take a closer look at the "illegal instruction" with
firefox -g. At the crash point in gdb, run: layout asm; set arm
fallback-mode arm; tui disable; disas /r ,. Initially it gets confused about the instruction layout,
but after trying different ranges it'll eventually decode properly:

(gdb) disas /r 0xf458bb28,0xf458bb3e
Dump of assembler code from 0xf458bb28 to 0xf458bb3e:
   0xf458bb28:  92 2c 44 f2 vfma.f32d18, d20, d2
   0xf458bb2c:  93 3c 44 f2 vfma.f32d19, d20, d3
   0xf458bb30:  b0 01 20 f2 vorrd0, d16, d16
   0xf458bb34:  b1 11 21 f2 vorrd1, d17, d17
   0xf458bb38:  b2 21 22 f2 vorrd2, d18, d18
   0xf458bb3c:  b3 31 23 f2 vorrd3, d19, d19
End of assembler dump.

However, those are exactly the instructions specified for _sk_xor__vfp4
in SkJumper_generated.S. It's hard to see how the compiler or binutils
could be directly responsible for generating an illegal instruction
here.

You can actually hexedit libxul.so and change those four vorr
instructions into NOPs. Firefox then makes it past this point but
crashes obscurely elsewhere, with different crash signatures on Firefox
58 vs 59.

Firefox arm64 (Pi 3 or other 64-bit board required) 58 and 59 still
work.

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

Darn, and I see the same error with Firefox 59. Your stack trace still
shows the illegal instruction in sk_xor__vfp4(). It seems like something
is now running Skia even when it's disabled in the config.

Among rendering differences, from the Firefox 58 blog post there's those
changes for OMTP which could have affected this:
https://mozillagfx.wordpress.com/2017/12/05/off-main-thread-painting/

If it's now going into Skia when it shouldn't that's a Firefox 58
regression. It would be somewhat of a bug affecting non-armhf platforms
too so we could finally get the attention of the Mozilla team.

Meanwhile the bad assembly in SkJumper_generated.S still seems like an
Ubuntu-specific problem. Is anyone able to reach the Ubuntu dev team on
IRC so that can set this bug's status back to "confirmed"?

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

levente,

I'm not sure how Lars and Sam Tygier (#1732954) are getting useful
backtraces. Might have something to do with running 17.10?

> ii firefox 57.0.4+build1-0ubuntu0.16.04.1 armhf

I see you're using 16.04. I should have mentioned that the workaround of
disabling Skia is something I verified using the 14.04 Trusty package
(on Raspbian). The flag also seems sufficient for Firefox to run on
17.10, but from what I can tell there's a second crash specific to the
16.04 build. To avoid that unknown, you can download and install the
Trusty .deb (via dpkg -i) even if your system is 16.04 Xenial:
https://launchpad.net/ubuntu/trusty/armhf/firefox/57.0.4+build1-0ubuntu0.14.04.1

[Desktop-packages] [Bug 1711337] Re: Firefox crashes at start on armv7L after 55.0.1 update

[James Donald]

Thanks for providing the stack trace, Lars.

This shows the illegal instruction is happening in Skia, specifically
SkJumper's implementation of _sk_xor__vfp4. To run with Skia disabled,
edit your user profile at ~/.mozilla/firefox/*.default/prefs.js and add
the following line:

user_pref("gfx.content.azure.backends", "");

Firefox 32-bit will then launch on Raspbian Stretch. Or if you have more
than one user, you can instead edit /usr/lib/firefox/defaults/pref
/vendor-gre.js

I expect rendering performance is taking a hit with Skia disabled. For a
proper fix we should figure out what's going on with the illegal
instruction(s) in SkJumper_generated.S. This file is auto-generated so
from what I can tell the armv7 version isn't readily available via git.
I have yet to set up a build environment for Firefox, but if someone
here has done so for Arch Linux and another for Ubuntu, we can diff and
track this down.

[James Donald]

That fix was:
>   * Hopefully fix LP: #1711337 by building the armhf build with
> -fno-schedule-insns to work around a compiler bug
?

According to 
https://launchpadlibrarian.net/351233449/buildlog_ubuntu-xenial-armhf.firefox_57.0.3+build1-0ubuntu0.16.04.1_BUILDING.txt.gz
 it's building with:
> --enable-optimize=-g -O2 -fno-schedule-insns

So it looks like the fix was indeed ported, but given the word
"hopefully", but was it ever confirmed?

Just like Adam Smith with version 55, arm64 appears to be fine. And just
like herrtimson with version 55, even armv7 works on Arch Linux but
still crashes on Debian/Ubuntu:
