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 behavior. Bootstrapped and regtested on x86-64-pc-linux-gnu. Ok for trunk? Thx, Haochen gcc/ChangeLog: * config/i386/i386-expand.cc (ix86_expand_builtin): Change from XImode to BLKmode. * config/i386/i386.md (ldtilecfg): Change XI to BLK. (sttilecfg): Ditto. --- gcc/config/i386/i386-expand.cc | 2 +- gcc/config/i386/i386.md | 12 +++++------- 2 files changed, 6 insertions(+), 8 deletions(-) diff --git a/gcc/config/i386/i386-expand.cc b/gcc/config/i386/i386-expand.cc index 9a31e6df2aa..d9ad06264aa 100644 --- a/gcc/config/i386/i386-expand.cc +++ b/gcc/config/i386/i386-expand.cc @@ -14198,7 +14198,7 @@ ix86_expand_builtin (tree exp, rtx target, rtx subtarget, op0 = convert_memory_address (Pmode, op0); op0 = copy_addr_to_reg (op0); } - op0 = gen_rtx_MEM (XImode, op0); + op0 = gen_rtx_MEM (BLKmode, op0); if (fcode == IX86_BUILTIN_LDTILECFG) icode = CODE_FOR_ldtilecfg; else diff --git a/gcc/config/i386/i386.md b/gcc/config/i386/i386.md index de9f4ba0496..86989d4875a 100644 --- a/gcc/config/i386/i386.md +++ b/gcc/config/i386/i386.md @@ -28975,24 +28975,22 @@ (set_attr "type" "other")]) (define_insn "ldtilecfg" - [(unspec_volatile [(match_operand:XI 0 "memory_operand" "m")] + [(unspec_volatile [(match_operand:BLK 0 "memory_operand" "m")] UNSPECV_LDTILECFG)] "TARGET_AMX_TILE" "ldtilecfg\t%0" [(set_attr "type" "other") (set_attr "prefix" "maybe_evex") - (set_attr "memory" "load") - (set_attr "mode" "XI")]) + (set_attr "memory" "load")]) (define_insn "sttilecfg" - [(set (match_operand:XI 0 "memory_operand" "=m") - (unspec_volatile:XI [(const_int 0)] UNSPECV_STTILECFG))] + [(set (match_operand:BLK 0 "memory_operand" "=m") + (unspec_volatile:BLK [(const_int 0)] UNSPECV_STTILECFG))] "TARGET_AMX_TILE" "sttilecfg\t%0" [(set_attr "type" "other") (set_attr "prefix" "maybe_evex") - (set_attr "memory" "store") - (set_attr "mode" "XI")]) + (set_attr "memory" "store")]) (include "mmx.md") (include "sse.md") -- 2.31.1
