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.
