--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The intrinsics guide:
https://www.intel.com/content/www/us/en/docs/intrinsics-guide/index.html#text=_mm_prefetch&ig_expand=5152,5153
_MM_HINT_T0 // 3, move data using the T0 hint. The PREFETCHT0 instruction will
be generated.
_MM_HINT_T1 // 2, move data using the T1 hint. The PREFETCHT1 instruction will
be generated.
_MM_HINT_T2 // 1, move data using the T2 hint. The PREFETCHT2 instruction will
be generated.
So GCC is correct here.
