Hi,
what makes you think this? -fomit-frame-pointer is a generic
optimization option, while -momit-leaf-frame-pointer is x86 and x86-64
specific.
It's always good to take a look into the fine gcc manual:
`-fomit-frame-pointer'
Don't keep the frame pointer in a register for functions that
don't need one. This avoids the instructions to save, set up and
restore frame pointers; it also makes an extra register available
in many functions. *It also makes debugging impossible on some
machines.*
`-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 `-fomit-frame-pointer' removes the frame pointer for
all functions which might make debugging harder.
OK, it really sounds similar.
