[PATCH] Do not set -fomit-frame-pointer if TARGET_OMIT_LEAF_FRAME_POINTER_P.

[Martin Liška]

Hi.

I'm not fully sure about the change, but -momit-leaf-frame-pointer
probably should not globally omit frame pointers?

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Ready to be installed?
Thanks,
Martin

        Do not enable -fomit-frame-pointer with -momit-leaf-frame-pointer
        as it will globally omit pointers (like in ira.c).
