Bug 21453 – gcc 3.3 cannot compile emacs-cvs on ~x86 with -O3

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description James Cloos 2003-05-21 23:47:25 UTC]

On ~x86, CFLAGS="-march=pentium3 -O3" gcc 3.3 (which was also compiled with that
CFALGS) cannot compile emacs-cvs; the binaries compile but do not give accurate
results when run.

Changing CFLAGS via s/-O3/-O2/ fixes the bug.

(I'd've set the Initial State to RESOLVED if the form allowed it....)

by policy, should'nt all cvs ebuilds be removed from tree ?

> by policy, should'nt all cvs ebuilds be removed from tree ?

That would be a less than helpful/useful result....

how about gcc 3.3.2 ?
any news ?

[Comment 4 James Cloos 2003-10-30 05:00:51 UTC]

Interesting timing; 3.3.2 just finished merging a few minutes before I got
this mail.... :)

I've been using -O2 exclusively since the first reply to this, but I will
give -O3 a try after some more stuff merges.

thank you,

Alex

I've used emacs-cvs for as long as its been in portage, with the same CFLAGS you have without a problem.  It is known to work with gcc-3.3.x and 3.4.  

Could you elaborate on what you mean by "the binaries compile but do not give accurate results when run"?

Also note that, app-editors/emacs-cvs unsets CFLAGS since June 2003.
