Hi, I am encountering a build issue in pixman when compiling with with clang.
pixman-mmx.c:100:20: error: constraint 'K' expects an integer constant expression : "y" (__A), "K" (__N) The error happens because __N is a function parameter and clang does not process it as an integer literal by design. Note that even gcc cannot handle it in -O0 mode. This can be fixed by forcing the macro version of the function which exposes __N value as an integer literal. I am making it #if 0 but it might be worthwhile to delete the function declaration since there is no much to lose here given all the function does is inline asm. diff -Nuar old/pixman/pixman-mmx.c new/pixman/pixman-mmx.c --- old/pixman/pixman-mmx.c +++ new/pixman/pixman-mmx.c @@ -89,7 +89,7 @@ return __A; } -# ifdef __OPTIMIZE__ +# if 0 extern __inline __m64 __attribute__((__gnu_inline__, __always_inline__, __artificial__)) _mm_shuffle_pi16 (__m64 __A, int8_t const __N) { Thanks, Manoj
