Subject: [PATCH] x86: Cast stride to __PTRDIFF_TYPE__ in AMX intrinsics
Date: Mon, 22 Aug 2022 10:02:44 -0700 [thread overview]
Message-ID: <20220822170244.670691-1-hjl.tools@gmail.com> (raw)
On 64-bit Windows, long is 32 bits and can't be used as stride in memory
operand when base is a pointer which is 64 bits. Cast stride to
__PTRDIFF_TYPE__, instead of long.
PR target/106714
* config/i386/amxtileintrin.h (_tile_loadd_internal): Cast to
__PTRDIFF_TYPE__.
(_tile_stream_loadd_internal): Likewise.
(_tile_stored_internal): Likewise.
