__builtin_return_address and -fomit-frame-pointer

[jbmailbox]

Dear all,

I am planning to use to __builtin_return_address to get the caller's
address of a function.  My understanding is that this built-in function
uses frame pointers (PUSH EBP to the stack) to track caller functions
of multiple levels.

If this is correct, does that also mean omit-frame-pointer compiler
option has to always be OFF when __built_return_address(1) is used?

Thanks,
Best Regards,
Johnny
