This problem is seen while compiling linux kernel 2.6.16 with GCC 4.x
when compiling the below test case. Compiler produced errors attached at the
bottom. This does not happen with GCC 3.4.x but I could reproduce this with GCC
4.0 GCC 4.1.0 GCC 4.1.1 and GCC 4.2(trunk)
xx.c
==========================
static inline __attribute__((always_inline)) int foo(void *p)
{
return 0;
}
inline __attribute__((always_inline)) int bar(void *p)
{
return 0;
}
void baz(void *p)
{
if (bar(p))
foo(p);
}
=====================
how to reproduce
gcc -c xx.c
=========================
errors as seen:
xx.c: In function 'baz':
xx.c:7: sorry, unimplemented: inlining failed in call to 'bar': function body
not available
xx.c:12: sorry, unimplemented: called from here
