You have not given a single example of where -fno-omit-frame-pointer would be
useful on ia64. Note that on ia64, -fno-omit-frame-pointer does NOT maintain a
frame-chain, so turning it on won't simplify creating a stack-trace, even (you
still need to look at the unwind info to do that).
Please don't close the bug before giving a concrete example of where
-fno-omit-frame-pointer is useful.
If you want an example of someone insisting on using -fno-omit-frame-pointer for
debuggability reasons, take Pine. They are using "-O6 -fno-omit-frame-pointer"
and are apparently quite set on doing so for the forseeable future (at least I
couldn't convince them otherwise).
