Hi all, There are several typo in AVX512 intrins macro define. They will eventually result in errors with -O0. This patch will fix that. Bootstrapped on x86-64-pc-linux-gnu. Ok for trunk and backport to GCC14, GCC 13 and GCC 12? Thx, Haochen gcc/ChangeLog: * config/i386/avx512dqintrin.

[PATCH] i386: Change prefetchi output template

Hi all, For prefetchi instructions, RIP-relative address is explicitly mentioned for operand and assembler obeys that rule strictly. This makes instruction like: prefetchit0 bar got illegal for assembler, which should be a broad usage for prefetchi. Explicitly add (%rip) after funct

[PATCH] i386: Use BLKmode for {ld,st}tilecfg

Hi all, For AMX instructions related with memory, we will treat the memory size as not specified since there won't be different size causing confusion for memory. This will change the output under Intel mode, which is broken for now when using with assembler and aligns to current binutils behavio

[PATCH] i386: Correct AVX10 CPUID emulation

Hi all, AVX10 Documentaion has specified ecx value as 0 for AVX10 version and vector size under 0x24 subleaf. Although for ecx=1, the bits are all reserved for now, we still need to specify ecx as 0 to avoid dirty value in ecx. Bootstrapped on x86-64-pc-linux-gnu. Ok for trunk and backport to GCC

[PATCH] Add AVX10.1 target_clones support

Hi all, Since AVX10 is the first major ISA introduced after AVX-512, we propose to add target_clones support for it. Although AVX10.1-256 won't cover 512-bit part of AVX512F, but since it is only for priority but not for implication, it won't be an issue. Bootstrapped and regtested on x86_64-pc-

[PATCH 2/2] Align tight&hot loop without considering max skipping bytes.

[PATCH 1/2] Adjust generic loop alignment from 16:11:8 to 16 for Intel processors

Previously, we use 16:11:8 in generic tune for Intel processors, which lead to cross cache line issue and result in some random performance penalty in benchmarks with small loops commit to commit. After changing to always aligning to 16 bytes, it will somehow solve the issue. gcc/ChangeLog:

[PATCH] i386: Fix behavior for both using AVX10.1-256 in options and function attribute

Hi all, When we are using -mavx10.1-256 in command line and avx10.1-256 in target attribute together, zmm should never be generated. But current GCC will generate zmm since it wrongly enables EVEX512 for non-explicitly set AVX512. This patch will fix that issue. Regtested on x86_64-pc-linux-gnu.
