Bug 41398 – GCC ebuild crashed on bootstrap with -Os in CFLAGS

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Gary Stein 2004-02-12 10:36:00 UTC]

Trying to bootstrap a minimal system using the Os from the begining
to keep all the binaries small.  However, gcc crashes I beleive on
the second stage of bootstrap when it tries to use -O2s in the
CFLAGS, which is a bad statement

I tracked it down to this line of code in the ebuild
export CFLAGS="$(echo "${CFLAGS}" | sed -e 's|-O[0123456789]\?|-O2|g')";

it doesn't account for -Os, so it makes it -O2s, I'm retrying
now adding s to the list of characters in the regex

to see if it works, but It does work using -O2 on the same computer
but I'd like to start with -Os if possible, if not, I can do it later

Reproducible: Always
Steps to Reproduce:
1.add -Os to CFLAGS in make.conf
2.run bootstrap.sh

Actual Results:  
failed with illegal CFLAGS

Expected Results:  
not fail, but replace the -Os with -O2 as needed

forgot to mention this was gcc-3.3.2-r7.ebuild
since I had ~x86 (not smartest Idea)

previous ebuilds like gcc-3.3.1-r1.ebuild use:
export CFLAGS="${CFLAGS/-O?/-O2}"

rsync and try again please.

that did it when you added the -O[0-9s] in the sed expression

thanks
