The result of test case

Description of problem:
gcc -Q --help=optimize shows:
$ LANG=C gcc -O1 -Q --help=optimize | grep fomit-frame-pointer
  -fomit-frame-pointer        		[disabled]

However with compiling the attached code, with "gcc -O1" frame pointer actually seems omitted when compared with the result from "gcc -O1 -f{no-,}omit-frame-pointer". So it seems that the information from "gcc -Q --help=optimize" seems incorrect.

Version-Release number of selected component (if applicable):
$ uname -a
Linux localhost.localdomain 3.5.2-1.fc17.i686 #1 SMP Wed Aug 15 16:52:27 UTC 2012 i686 i686 i386 GNU/Linux

$ LANG=C gcc -v

How reproducible:
See attached tarball:
gcc-O1-default-opt.txt: result of "gcc -O1 -Q --help=optimize"
gcc-O1-omit-opt.txt: result of "gcc -O1 -fomit-frame-pointer -Q --help=optimize"
gcc-O1-noomit-opt.txt: result of "gcc -O1 -fno-omit-frame-pointer -Q --help=optimize"
test-O1-default.S: gcc -O1 -S test.c
test-O1-noomit.S: gcc -O1 -fno-omit-frame-pointer -S test.c
test-O1-omit.S: gcc -S -O1 -fomit-frame-pointer test.c

Steps to Reproduce:
1. See above
2.
3.
  
Actual results:
gcc -O1 -Q --help=optimize says -fomit-frame-pointer is disabled, however the result of gcc -S shows that actually frame pointer is omitted

Expected results:
gcc -O1 -Q --help=optimize should show that -fomit-frame-pointer is enabled
