gcc: Fix peephole optimization bug for sh3 (PR port-sh3/56311)
Cherry-picked from upstream:
https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=4dbb3af1efe55174a714d15c2994cf2842ef8c28
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101469
Now, the PR confirmed fixed. No regression observed for full ATF run on
landisk (compared with GCC built with this peephole optimization being
removed by hand).
We thank Oleg Endo, the author of the upstream commit.
Also thanks hgutch@ and uwe@ for analysis.

I'm against the policy of restoring the /proc dependency for this corner case in one application. We need to upstream the NetBSD specific patches to mainline GCC. I'm also one who feels hesitate to import Linux'ism into our basic components. However, for this problem in particular, I still think it is not a good choice to keep NetBSD support in driver-aarch64.c: (a) Our sysctl(3)-based interface is not compliant to any standards, just like Linux's /proc/cpuinfo. But the latter is, unfortunately for us, the de facto standard. (b) Because of (a), driver-aarch64.c is deeply depended on /proc/cpuinfo. Our NetBSD support code see diff to vendor branch here: http://cvsweb.netbsd.org/bsdweb.cgi/src/external/gpl3/gcc/dist/gcc/config/aarch64/driver-aarch64.c.diff?r1=1.1.1.7=1.10=h is something like a "glue code" which converts our convention to /proc/cpuinfo style. We already do this in procfs. Why twice? (c) I imagine that there would be little benefits for upstream to merge NetBSD support into their repository. If they will merge, I don't think the code is kept updated. (d) Only -march=native and -mtune=native depends on this feature. I'm OK with /proc/cpuinfo is left as is; only enabled when -onolinux is not specified. IMO, it is users' responsibility that such a additional feature fails with their non-standard system settings. In short, I'm worried about future when mrg@ or someone else have to maintain our glue code eternally, if this code is not reverted. Thanks, rin

You can, but it isn't needed these days -- I used to mount procfs twice, once without the linux option, on /proc, and once with, on /emul/linux/proc) but there seems to be little point in that any more (even though the linux /proc has a whole bunch of trash that has nothing to do with processes, and should be, and generally is, available from /kern ... /proc/cpuinfo is an example of that, though that one is missing from kernfs and should be added there). I do add "hidden" to the mount option list though, there's essentially no point in including /proc /kern /dev/pts (or anything else like those) in default df output (which is the only thing "hidden" generally affects). kre

My NetBSD system has no /kern and no /proc, do I need to mkdir these directories? I just did. kernfs and procfs were commented out in /etc/fstab .

Unfortunately this breaks building on a 9.0 arm64 host because it is
picking up /usr/include/aarch64/armreg.h and the one in 9.0 is missing a
bunch of stuff. It works when using armreg.h from the source tree instead,
eg:
-#include
+#include "/path/to/src/sys/arch/aarch64/include/armreg.h"

src/external/gpl3/gcc/dist/gcc/config/aarch64: driver-aarch64.c
Log Message:
slightly reduce the scope of #ifdef __NetBSD__ version of the
-m{cpu,tune,arch}=native handling code, and hopefully reduce
future effort by aligning inputs
- share common variables and setup more
- build a linux/arm64 like /proc/cpuinfo Features line and
use that to match the new 'list of features' per gcc feature,
based upon our sysctl(2) published info. complete this list
for all supported extensions.
now this feature works again.

revert the rs6000/netbsd64.h change and put it back as

Re: CVS commit: src/external/gpl3/gcc/dist/gcc, vax crashes
For future reference, proably by me:
Reproducer for the crash without the local diff:
#!/bin/sh
cat << EOF > oacc.i
int a, b;
int e() {
short *c = 0;
char d = c[a + 1];
b = d;
a += 2;
}
EOF
vax--netbsdelf-gcc -O2 -c oacc.i
This hits an assertion:
emit-rtl.c:2310 gcc_assert (memory_address_addr_space_p (mode, addr, as));
This points to vax code, vax_legitimate_address_p.
This function might not handle some addressing modes, possibly one of
these two:
c: b0 40 9f 02 movw *0x2[r0],r1
c: 98 40 a0 02 cvtbl 0x2(r0)[r0],15

The latter part seems quite wrong as the VAX calling convention generally requires reading the argument size from the stack... Joerg

It is also using the same mode for setting up the MMX registers and in turn, the stack slots reserved for spilling require 32bit alignment. The actual vector types used keep the original 64bit alignment, so when the compiler wants to spill a MMX register, it hits an assertion. Fix this by using the vector type as raw type for MMX registers. Doesn't that enforce a 64bit alignment when it isn't needed? Or have I misread the commit message? Misaligned transfers for stack slots for MMX are actually fine. Only the 128bit (and larger) accesses have to be aligned. The performance penalty of misaligned 64bit transfers really is best avoided by maintaining the stack alignment - and assuming it won't get misaligned. I suspect that the 'sub %sp,n' use to allocate a stack frame has hardware optimisations that are absent from the 'and %sp,~7' needed to realign it. David -- David Laight: da...@l8s.co.uk

This consists of two parts: - for NetBSD/i386 and NetBSD/AMD64 with -m32, use a default stack alignment of 23bit as specified by the ABI - ensure that double and long long variables on the stack are by default only aligned to 32bit, if there is nothing else in the function needing a larger stack alignment The combination ensures that SSE variables on the stack trigger the realignment logic, but just using double or long long doesn't.
