[PATCH] arc: Fix for new ifcvt behavior [PR104154]

Hi, I figured I'd just go ahead and post this patch as well since it seems to have fixed the arc build problems. It would be nice if someone could bootstrap/regtest if Jeff hasn't already done so. I was able to verify that the two testcases attached to the PR build cleanly but not much more. Th

[PATCH] x86: Fix -fsplit-stack feature detection via TARGET_CAN_SPLIT_STACK

From: Sören Tempel Since commit c163647ffbc9a20c8feb6e079dbecccfe016c82e -fsplit-stack is only supported on glibc targets. However, this original commit required some fixups. As part of the fixup, the changes to the gnu-user-common.h and gnu.h where partially reverted in commit 60953a23d57b13a672

[PATCH] Implement constant-folding simplifications of reductions.

This patch addresses a code quality regression in GCC 12 by implementing some constant folding/simplification transformations for REDUC_PLUS_EXPR in match.pd. The motivating example is gcc.dg/vect/pr89440.c which with -O2 -ffast-math (with vectorization now enabled) gets optimized to: float f (f

[PATCH v2, rs6000] Disable TImode from Bool expanders [PR100694, PR93123]

Hi, This patch disables TImode for Bool expanders. Thus TI register can be split to two DI registers during expand.Potential optimizations can be implemented after the split. The new test case illustrates it. Bootstrapped and tested on powerpc64-linux BE and LE with no regressions. Is this oka

[PATCH] PR tree-optimization/83907: Improved memset handling in strlen pass.

This patch implements the missed optimization enhancement PR 83907, by handling memset with a constant byte value in tree-ssa's strlen optimization pass. Effectively, this treats memset(dst,'x',3) as it would memcpy(dst,"xxx",3). This patch also includes a tweak to handle_store to address anothe

[PATCH] Improved constant folding for scalar evolution.

This patch adds a small (follow-up) optimization to chrec_apply for linear chrecs to clean-up the final value expressions sometimes generated by GCC's scalar evolution pass. The transformation of A+(X-1)*A into A*X is usually unsafe with respect to overflow (see PR92712), and so can't be performe
