Really? Sure - a few opcodes ... but in the grand scheme of things...
For example the function target_write_memory() - with "-O2" is exactly these
instructions
pushl %ebp
movl %esp, %ebp
movl 8(%ebp), %edx
popl %ebp
movl (%edx), %ecx
movl 64(%ecx), %ecx
jmp *%ecx
(A) 7 instructions, operating at 1ghz.
(B) if they are called "frequently enough" they live in the cache and are
faster!
(C) And because the code is "more common/reused" - identical 7 instruction
sequences in multiple places do not cause other identical 7 instruction
sequences (at another address) to leave the cache
The same argument can, to a degree, be made *against* 'static inline' functions
in headers.
