I seem to recall reading in the GCC mailing lists that -fomit-frame-pointer is the default on all builds now. I don't recall what version this was started. It would be easy enough to find out. Anyone with a x86 could start a GCC build and look at the first few times in the log where something is compiled and see if the flag is in the line. If you see it once, you will know it is now default. -- Randy rmlscsi: [bogomips 1003.28] [GNU ld version 2.16.1] [gcc (GCC) 4.0.3] [GNU C Library stable release version 2.3.6] [Linux 2.6.14.3 i686] 15:51:00 up 29 days, 22:45, 1 user, load average: 0.24, 0.25, 0.26 -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
