x86: Properly implement AMX-TILE load/store intrinsics
ldtilecfg and sttilecfg take a 512-byte memory block. With
_tile_loadconfig implemented as
extern __inline void
__attribute__((__gnu_inline__, __always_inline__, __artificial__))
_tile_loadconfig (const void *__config)
{
__asm__ volatile ("ldtilecfg\t%X0" :: "m" (*((const void **)__config)));
}
GCC sees:
(parallel [
(asm_operands/v ("ldtilecfg %X0") ("") 0
[(mem/f/c:DI (plus:DI (reg/f:DI 77 virtual-stack-vars)
(const_int -64 [0xffc0])) [1
MEM[(const void * *)_data]+0 S8 A128])]
[(asm_input:DI ("m"))]
(clobber (reg:CC 17 flags))])
and the memory operand size is 1 byte. As the result, the rest of 511
bytes is ignored by GCC. Implement ldtilecfg and sttilecfg intrinsics
with a pointer to XImode to honor the 512-byte memory block.
gcc/ChangeLog:
PR target/114098
* config/i386/amxtileintrin.h (_tile_loadconfig): Use
__builtin_ia32_ldtilecfg.
(_tile_storeconfig): Use __builtin_ia32_sttilecfg.
* config/i386/i386-builtin.def (BDESC): Add
__builtin_ia32_ldtilecfg and __builtin_ia32_sttilecfg.
* config/i386/i386-expand.c (ix86_expand_builtin): Handle
IX86_BUILTIN_LDTILECFG and IX86_BUILTIN_STTILECFG.

--- Comment #1 from H.J. Lu ---
The problem is that in
extern __inline void
__attribute__((__gnu_inline__, __always_inline__, __artificial__))
_tile_loadconfig (const void *__config)
{
__asm__ volatile ("ldtilecfg\t%X0" :: "m" (*((const void **)__config)));
}
only 8 bytes are used.
