I have never, with any version of Xcode, been able to make it inline
the code I want. Even the simplest functions, like,
inline int ff() {return 55;}
produce out of line code with jump and return instructions. That is
true for class member functions too. I have tried different
optimization levels to no effect. I don't see any compiler options
that seem to affect it. Anyone have an idea?
$ cat inline.c
static inline int a() { return 37; }
static __inline int b() { return 55; }
static __inline__ int c() { return 82; }
static __attribute__((always_inline)) int d() { return 78; }
int main()
{
return a() + b() + c() + d();
}
$ gcc -Wall -O3 inline.c -S
$ cat inline.s

.section __TEXT,__picsymbolstub1,symbol_stubs,pure_instructions,32
.machine ppc

.p2align 4,,15
.globl _main
_main:

If I remove the static, it emits out of line copies (of course), but
the code is still inlined.
