Thanks, Craig & Pengfei!
Yes, we miss the __inline__ in the header file.

Thanks

Seems attribute “__inline__” was missing in these intrinsics. Candidate patch https://reviews.llvm.org/D108509

Thanks

Aren’t the intrinsics usually marked inline? Would that prevent the warning?

Hi Devs,

We think the following function definitions should be attributed with
"unused" to avoid the below warnings .

include/amxintrin.h:255:13: warning: unused function '__tile_loadd'
[-Wunused-function]
static void __tile_loadd(__tile1024i *dst, const void *base,
            ^
/include/amxintrin.h:261:13: warning: unused function '__tile_dpbssd'
[-Wunused-function]
static void __tile_dpbssd(__tile1024i *dst, __tile1024i src1,
            ^
include/amxintrin.h:268:13: warning: unused function '__tile_stored'
[-Wunused-function]
static void __tile_stored(void *base, __SIZE_TYPE__ stride, __tile1024i src) {

include/amxintrin.h:273:13: warning: unused function '__tile_zero'
[-Wunused-function]

We can make the required changes and upstream the same .

Thank you
~Umesh
