An example from libhugetlbfs. Note the original call wasn't recursive,
following is reduced code I got from delta.
$ cat gethugepagesizes.c
extern __inline __attribute__ ((__always_inline__))
int open (__const char *__path, int __oflag, ...)
{
}
void cleanup (void);
open (const char *file, int flags, ...)
{
char fname[4096 + 1];
int fd;
cleanup ();
fd = open (fname, 01 | 0100);
}
void cleanup (void)
{
cleanup_fake_data ();
}
$ ~/install/gcc/trunk/bin/gcc -O3 -c gethugepagesizes.c
gethugepagesizes.c: In function 'open':
gethugepagesizes.c:7:1: sorry, unimplemented: inlining failed in call to
'open': redefined extern inline functions are not considered for inlining
gethugepagesizes.c:12:6: sorry, unimplemented: called from here
