[PATCH] PR tree-optimization/105668: Provide RTL expansion for VEC_COND_EXPR.

This resolves PR tree-optimization/105668, a P1 ice-on-valid regression triggered by my recent patch to add a vec_cmpeqv1tiv1ti define_expand to the i386 backend. The existence of this optab currently leads GCC to incorrectly assume the existence of a corresponding vcond_mask for V1TImode. I bel

[PATCH V2]rs6000: Store complicated constant into pool

Hi, And after some discussions in the previous review: https://gcc.gnu.org/pipermail/gcc-patches/2022-March/591509.html This patch simply updates the rtx_cost hook to accurate cost on constant by using 'COSTS_N_INSNS' with 'num_insns_constant'. This could avoid CSE eliminate constant loading.

Re: [PATCH] rs6000: add support for sanitizers on FreeBSD

Ping. FreeBSD has already enabled sanitizers in its base system in https://cgit.freebsd.org/src/commit/?id=f5024381ac16ba43d37a8bd32d54c27f6a6afa66 The upstream (LLVM) patch was reviewed by a couple of people already. Our llvm-devel port also has sanitizers enabled by default since https://cgit

[PATCH] Minor improvement to genpreds.cc

This simple patch implements Richard Biener's suggestion in comment #6 of PR tree-optimization/52171 (from February 2013) that the insn-preds code generated by genpreds can avoid using strncmp when matching constant strings of length one. The effect of this patch is best explained by the diff of
