I will nominate the following as a test case. It should compile without errors: for each affected arch: gcc test_case.c gcc test_case.c -maltivec gcc test_case.c -faltivec gcc test_case.c -maltivec -DINCLUDE_HEADER test_case.c: #include <stdio.h> #if defined( INCLUDE_HEADER ) #include <altivec.h> #endif /* The approved method for detecting PIM availability on GCC */ #if defined( __VEC__ ) #if defined( __GNUC__ ) && ! defined __APPLE_ALTIVEC__ #if defined _ALTIVEC_H /* defined by altivec.h */ #define __ALTIVEC_PIM__ #endif #else #define __ALTIVEC_PIM__ #endif /* __GNUC__ */ #endif /* __VEC__ */ int main( void ) { #if defined( __ALTIVEC_PIM__ ) vector unsigned char v = (vector unsigned char) ( 'A','l','t','i','V','e','c',' ','i','s',' ','o','n', 0, 0, 0 ); v = vec_or( v, v ); printf( "%vc\n", v ); //note, some operating systems don't support %v format specifiers, which is a separate problem #else printf( "AltiVec is off\n" ); #endif return 0; } -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30254
