I tried the following: #include <stdio.h> inline int foo() { printf("%s %x\n",__func__,0x12345); } int main () { foo(); } The assembly code generated for main is: 0000000000400470 <main>: 400470: b9 45 23 01 00 mov $0x12345,%ecx 400475: ba 4b 06 40 00 mov $0x40064b,%edx 40047a: be 44 06 40 00 mov $0x400644,%esi 40047f: bf 01 00 00 00 mov $0x1,%edi 400484: 31 c0 xor %eax,%eax 400486: e9 d5 ff ff ff jmpq 400460 <__printf_chk@plt> That is, the call to foo seems tom be inlined. But the output is: foo 12345 So it seems that __func__ is determined before inlining. julia -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
