2024-08-07system/gcc: Fix TSan on PPC64A. Wilcox2-0/+61
2024-08-07system/gcc: Fixes for 32-bit Arm platformsA. Wilcox3-26/+41
* The san library needs some adjustments to handle the fact we need frame pointers (r7 is used for the syscall number, and the FP). * Fix GCC Go __go_mmap external linking since they changed the signature upstream for the C side. This closes #1201.
2024-08-07system/gcc: Fix libsan on ppc64 and i586 bugA. Wilcox3-5/+64
Closes: #1217, #1218
2024-08-07system/gcc: Add sanitizer supportA. Wilcox2-3/+172
Based-ish on Chimera's patches, but a bit more thorough. * 32-bit ports don't have liblsan or libtsan. * We can't dep on utmps-dev for utmpx, so hard-code size. The size is the same on all six arches per my testing.
2024-08-07system/gcc: Update to 13.3.0A. Wilcox48-1058/+6085
0012-static-pie and 201-ada were forward-ported by my own paws. Three digit 0xx underscore patches are from Gentoo. This is also the source of the insn-split and match-split patches, which significantly increase performance on build. They are also the source of the new configure option --with-matchpd-partitions. On systems with very many cores/threads, a number higher than 32 would probably perform even better, but 32 should give decent perf on 8+ threads, and runs quite nicely on the 64-thread Talos II I ran the testbuild on. 202 is from Void. The 300s are originally written by me. The Ada patch now includes an improvement to use posix_openpt instead of getpt, which fixes link errors later on. We also now use STAGE1_CFLAGS and BOOT_CFLAGS to improve build times. Improvement was clocked from 40m to 32m (-8m, or 20%) on gwyn. The patch for Go name mangling is needed to build packages that use reflect2, which includes user/gitlab-runner.
2023-10-03system/gcc: Fix static PIE linking specA. Wilcox2-3/+3
On 32-bit ARM, -Bsymbolic isn't enough. -Bstatic should be correct on all platforms, and should fix static PIE linking on armv7. Ref: #1070
2023-05-12remove erroneous files. fixes #828.Zach van Rijn2-175/+0
2023-01-02system/gcc: Finish fixing unwinding in GCC Go rtA. Wilcox2-2/+44
We add more functions to the unwind string comparisons, and pull in the symbols for libucontext. Fixes: 0dd86764 ("system/gcc: Ensure gccgo doesn't run off the stack") Refs: #832
2022-12-25system/gcc: Ensure gccgo doesn't run off the stackA. Wilcox2-0/+20
libucontext doesn't clear the stack frame below makecontext. This caused us to end up crashing like Solaris[1]. Fixes: #832 [1]: https://gcc.gnu.org/PR52583#c21
2022-12-25system/gcc: Make ARMv7 unwind macros functionsA. Wilcox2-3/+58
This workaround is already needed upstream for FreeBSD. Let's go ahead and use the same workaround for musl. We also ensure they are not declared `inline` so that they are available as library functions. We also have a hack in place for the stage1 Ada driver due to their own hack pulling in the Arm unwind functions directly without linking. Fixes: #866 (and probably more as we continue building packages)
