Bug 54415 – Stage 1 bootstrapping on athlon-xp had a internal compiler error while building coffgen.c

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Jeff Cooper 2004-06-19 06:30:06 UTC]

During a stage1 bootstrapping on a Athlon-XP, I got the following error from the 'scripts/bootstrap.sh' step:

coffgen.c: In function `coff_write_symbol':
coffgen.c:954: internal compiler error: Didn't find a coloring.

The last entry in emerge.log is:

1087605823:  >>> emerge (6 of 6) sys-devel/binutils-2.14.90.0.8-r1 to /
1087605823:  === (6 of 6) Cleaning (sys-devel/binutils-2.14.90.0.8-r1::/usr/portage/sys-devel/binutils/bin

1087606110:  *** terminating.

My CFLAGS are listed below.

Reproducible: Always
Steps to Reproduce:
1.Start doing a stage1 install (2004.1), following the instructions at: http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=6
2.Get to the step of Bootstrapping the system and run '
scripts/bootstrap.sh'

Actual Results:  
bootstrap failed, internal compiler error.

Expected Results:  
It should have compiled without failing! :-)

-fnew-ra is known to be buggy. Take it out and you should be fine.

[Comment 3 Benjamin Judas (RETIRED) 2004-07-04 23:50:29 UTC]

Is this bug still an issue or is the problem solved?

[Comment 4 Travis Tilley (RETIRED) 2004-07-14 09:34:34 UTC]

fnew-ra
    Use a graph coloring register allocator. Currently this option is meant only for testing. Users should not specify this option, since it is not yet ready for production use. 

that should say it all. plus you should never use -ffast-math as a global cflag, it's almost as broken when used that way.
