Hi! While looking at some other PR, I've stripped line notes and got pr59947.ii.bak:26330:74: error: ISO C++ forbids declaration of ‘_mm512_mask_cvtusepi64_storeu_epi32’ with no type [-fpermissive] _mm512_mask_cvtusepi64_storeu_epi32 (void* __P, __mmask8 __M, __m512i __A) ^ pr59947.ii.bak: In function ‘float _cvtsh_ss(short unsigned int)’: pr59947.ii.bak:30674:65: warning: narrowing conversion of ‘__S’ from ‘short unsigned int’ to ‘short int’ inside { } [-Wnarrowing] __v8hi __H = __extension__ (__v8hi){ __S, 0, 0, 0, 0, 0, 0, 0 }; ^ warnings that would normally only show up with -Wsystem-headers. Especially the second one looks like one worth fixing.
