Actually -fno-omit-frame-pointer is used for other reasons. Also there is no
reason for -fno-omit-
frame-pointer on x86 now with variable tracking code. -fno-omit-frame-pointer
comes into play for
other reasons which are not documented, I cannot remember them.
Also frame pointers are used sometimes even with -fomit-frame-pointer due to
nested functions.
Also there are also other targets which are the same situation as ia64 and this
has not changed for
them yet (eg PPC), in fact PPC support has been in GCC before the EGCS spilt so
I assume this has been
discussed before and there is no benefit from disabling this flag on those
targets.
I think some people's code depends on there being a frame pointer and changing
this to a target
dependent flag would be a problem because their code runs on more than one
target.
I am just going to close this as invalid as there is no reason why someone
should be using this flag
anyways unless they need the frame pointer in general.
