aligned at least to 4 byte boundary. This enables more inlining, increase code
size, but may improve performance of code that depends on fast memcpy, strlen
and memset for short lengths.
@item -momit-leaf-frame-pointer
@kindex -momit-leaf-frame-pointer
Don't keep the frame pointer in a register for leaf functions. This
avoids the instructions to save, set up and restore frame pointers and
makes an extra register available in leaf functions. The option
@samp{-fomit-frame-pointer} removes the frame pointer for all functions
which might make debugging harder.
