The second patch (that pulls in tree.h into recog.h) breaks building for me on
an usual amd64 Linux system:

Starting with g:21e2ef2dc, I see a new ICE building a PPC Linux kernel for the
adder875_defconfig config (see eg.
http://toolchain.lug-owl.de/laminar/jobs/linux-powerpc-adder875_defconfig/100):

Thanks a lot!  I scheduled builds for the three affected targets (from my
target list.) The box is quite loaded right now (and a few jobs a before those
three), so I guess it'll take a few hours.

But the basic question is: Should a first build pass --disable-gcov (glibc's
failure to provide this) or should GCC detect that there's (not yet) no
sys/mman.h (GCC problem)?

I see this as well for my CI builds using a (slightly hacked to use local
copies of the GIT trees) build-many-glibcs.py (from glibc.)

If you call call:

--keep all --replace-sources -j 1
/var/lib/laminar/run/glibcbot-alpha-linux-gnu/21 checkout binutils-vcs-master

(as an example, use the Alpha builds at

actual breakage for example at

Don't know how much effort to put into this. m32c has some very old PRs which
look rather trivial, with no maintainer listed, so it's maybe ... dead already?

Sure, just a warning, but still there (as of

get that understood/fixed?

Compiler builds for me and the ICE went away for all affected Linux
configurations. Though I cannot verify whether or not the generated code is
correct.

I'll give that patch a spin, build the cross-compilers and try to build the
affected Linux configurations.

This seems to be also an asm goto issue, but it is _not_ fixed with the
7676235f690e624b7e commit. (This issue can still be reproduced with
2dc5d6b1e7e.)

Minimum command line to produce the ICE is: `powerpc64-linux-gcc -Os -g -c -o
align.o align.i`. Removing either `-Os` or `-g` silences it.

I gave that patch a try: GCC build is successful, as is the Linux build
afterwards using that toolchain. (Cannot test the resulting kernel of
course---I don't have the hardware.)

Hi!

Starting with commit fd8dd6c0384969170e594be34da278a072d5eb76, I see
Linux kernel build errors for the skiroot_defconfig:

Just ftr: Building GDB with a recent GCC now breaks since GDB is testing
-Wself-move in its unittests, but only covers the warning in case of clang.
Found by my automated builders. I proposed a patch to fix that.

Hi!

The optimization prepared in PR103798 ("memchr with a (small) constant string

(Initial report can be found at

Martin Sebor already had a look at it (cf.
https://gcc.gnu.org/pipermail/gcc/2021-September/237383.html) and suggested to
explicitely make reg_class an unsigned enum, or to add gcc_unreachable() for <
0 to indicate the non-negativeness of sclass/dclass.

Preprocessed / minimized testcase attached (based on --target=nvptx-none),
build with a recent GCC:

Calling the compiler again with just adding -fanalyzer doesn't add more
information to the output. Do I need to turn on extra warnings to enable static

Unfortunately, the toolchain testing host isn't yet publically hosted, so it's
not yet IPv4-reachable... Once moved to the DC, I'll announce it.

Hi!

I don't know the code behind -Wmaybe-uninitialized, but maybe it's possible to
show the path GCC considered when emitting this message?

Right now, with Debian's "gcc-snapshot" compiler, I cannot successfully "make
all-gas" for the microblaze-elf and mcore-elf targets (with current binutils at
0b99a66053fa1e93a984f75a7a3d5343c74882fb) due to a maybe-uninitialized warning
in md_assemble() which is kind of unpleasant to find the possible way through
the assignment maze...

My personal impression is that usually, the maybe-uninitialized warnings are
quite helpful, but it's somewhat tedious to track them down. As I'm revamping
my toolchain testing efforts, these show up every now and then.

Thanks,
  Jan-Benedict

Hi!

After having started my testing efforts again, I found these two warnings which
might be legit for microblaze-linux.

Configured as:

--enable-languages=all --disable-gcov --disable-shared --disable-threads

using a recent master commit (1a87f8381085de50726634e8cb4a651c05b272b5) along
with a recent GCC as $CXX.

...and then it's built with:

Hi!

I started doing GCC testing again and found an issue with the h8/300 backend.

Used GCC is:

--- Comment #4 from Jan-Benedict Glaw  ---
This can IMHO be closed. Using a 11.0.1 based compiler (Debian "unstable"'s
"gcc-snapshot package) to build current GCC versions (ie. tested with
5e0236d3b0e0d7ad98bcee36128433fa755b5558 as of May 9th, 2021), the warning
doesn't appear. Indeed, the VAX backend recently got quite a major overhault by
Maciej.

Bug ID: 100255
   Summary: Crosscompiler to ia64-hp-vms: vmsdbgout.c:368:20:
error: ISO C++17 does not allow 'register' storage
class specifier [-Werror=register]
   Product: gcc
   Version: unknown
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: debug
  Assignee: unassigned at gcc dot gnu.org
  Reporter: jbg...@lug-owl.de
  Target Milestone: ---

I'm revamping my testing efforts, building cross compilers based on targets
listed in ./contrib/config-list.mk.

With .../configure --target=ia64-hp-vms --enable-werror-always
--enable-languages=all --prefix=/tmp/gcc-ia64-hp-vms (using g++ (Debian

compiler), build breaks (as of ed16241c6db23013d70b792a64f29080ad48a414) with
