I Noticed this on OSX with clang, though it likely happens elsewhere as well. The result is disabled x86_64 asm. Due to missing escaping, this $0 was interpreted as the function name SECP_64BIT_ASM_CHECK, causing the compile-check to be broken on some compilers. The actual check looked like this: int main() { uint64_t a = 11, tmp; __asm__ __volatile__("movq SECP_64BIT_ASM_CHECKx100000000,%1; mulq %%rsi" : "+a"(a) : "S"(tmp) : "cc", "%rdx"); return 0; } It seems even more odd that it compiled anywhere. |
