[PATCH] i386: Use macro to wrap up share builtin exceptions in builtin isa check

Hi all, Currently in i386, we have several ISAs share builtin between each other which is handled in ix86_check_builtin_isa_match with if condition clauses. The patterns for these clauses are quite similar so it will be more friendly for developers if we rewrite them as a macro. This patch adds

[PATCH] i386: Optimize vshuf{i, f}{32x4, 64x2} ymm and vperm{i, f}128 ymm

Hi, all The patch aims to optimize vshuf{i,f}{32x4,64x2} ymm and vperm{i,f}128. And it has regtested on x86_64-pc-linux-gnu. OK for trunk? Thanks. Lin vshuf{i,f}{32x4,64x2} ymm and vperm{i,f}128 ymm are 3 clk. We can optimze them to vblend, vmovaps when there's no cross-lane. gcc/ChangeLog:

Thanks a lot for the testing, Kees. Jakub, do you have any more comment on the 6th version of the patches? Is it ready for the GCC13 commit? Or we need to delay it to GCC14? This patch has been there waiting for approving for a while, I think that it’s a nice improvement to GCC and also help to

[PATCH] ipa: Fix double reference-count decrements for the same edge (PR 107769, PR 109318)

Hi, It turns out that since addition of the code that can identify globals which are only read from, the code that keeps track of the references can decrement their count for the same calls, once during IPA-CP and then again during inlining. Fixed by adding a special flag to the pass-through vari

Re: [PATCH v2] aarch64: disable LDP via tuning structure for -mcpu=ampere1/1a

OK for backport? This will be all the way down to GCC10, as I just realized that we need to backport the entire ampere1/1a support to GCC10 (we stopped at GCC11 for some unexplainable reason)... Philipp. On Mon, 17 Apr 2023 at 12:20, Philipp Tomsich wrote: > > Applied to master, thanks! > Phili

[PATCH] tree-optimization/109524 - ICE with VRP edge removal

VRP queues edges to process late for updating global ranges for __builtin_unreachable. But this interferes with edge removal from substitute_and_fold. The following deals with this by looking up the edge with source/dest block indices which do not become stale. For GCC 14 we probably want to ref
