# Notes about '-fno-omit-frame-pointer' flag:

# Frame pointer omission does make debugging significantly harder. Local

# expensive since they are far away from the top of the stack and may require
# more expensive addressing modes.
#
# The '-fno-omit-frame-pointer' option direct the compiler to generate code
# that maintains and uses stack frame pointer for all functions so that a
# debugger can still produce a stack backtrace even with optimizations flags
# (eg '-O1', '-O2', etc).
