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.
