akage. Hopefully the fix I'm testing
will cure this as
well (but an ICE is different symptom to a silent miscompilation).
Sorry again,
Roger

This breaks Ada on aarch64 in stage3, probably a miscompiled stage2
compiler. For example:
/opt/gcc/gcc-20220605/Build/./prev-gcc/xgcc
-B/opt/gcc/gcc-20220605/Build/./prev-gcc/ -B/usr/aarch64-suse-linux/bin/
-B/usr/aarch64-suse-linux/bin/ -B/usr/aarch64-suse-linux/lib/ -isystem
/usr/aarch64-su
I'd like to ping my patch for PR middle-end/95126 from February:
https://gcc.gnu.org/pipermail/gcc-patches/2022-February/590949.html
As a regression fix, this has missed GCC 12, but hopefully its suitable
for 13 now we're back in stage1.
The patch has been refreshed and retested against gcc 13 tr
11 matches
