[Bug c/33564] New: A static inline function as a parameter of another static inline function is not inlined.

[michaelferguson at acm dot org]

This is a duplicate of bug 1601, which I can't reopen.

This bug is still present on 4.1.2-13 (RedHat, 20070626) and 3.4.6-3 (RedHat
20060404). Looking at the produced assembly, f2 and fun are both produced; the
assembly should only produce fun and inline both f1 and f2. I havn't tested it
on 4.2.1 yet, but I'm reopening it because it was reported as fixed years ago.
I'm compiling the test given below with:
gcc -c -O3 --save-temps inline_test.c

How-To-Repeat (from bug 1601):
static inline int
f1( int (*f)(int y), int q )
{
  return( (*f)( q ) );
}

static inline int
f2( int z )
{
  return( z ^ 32 );
}

int fun( int x )
{
  return( f1( &f2, x ) );
}
