Bug 77548 – xorg-x11 ICE with -mfpmath=sse on gcc-3.3.4

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description shade266 2005-01-11 09:59:11 UTC]

While trying to update Xorg to the current-x11-base/xorg-x11-6.8.1.901 from Xorg version 6.8.0-r3. The compile would fail with the exact error message contained in the URL/thread I provided with my emerge info included. The compile also halted in the exact same place everytime.

Editing CFLAGS="" to indicate -02 as opposed to -03 and removing -mfpmath=sse allowed a successful compile of Xorg to occur.


Reproducible: Always
Steps to Reproduce:
1.The emerge info provided in the URL/thread will indicate system setup.
2.Emerge -u world xorg-x11 produces unsuccessful compile with above mentioned system setup.
3.Emerge of xorg-x11 alone with the above mentioned system setup.

Actual Results:  
The Xorg build would fail/halt with the below message(s). The exception being
the version of Xorg-x11 being 6.8.1.901 in this instance.

Emerge error output: gcc: Internal error: Trace/breakpoint trap (program cc1)

!!!(no error message) 

Expected Results:  
I expected a successful compile of the xor-x11 upgrade considering I compiled
the previous-6.8.0-r3-version with the exact CFLAGS="" and USE="". Thus being an
upgrade I would not have presumed any errors.

I also am requesting a replace-flag solution be included in the ebuild per
Earthwings' suggestion.

So, let me get this straight:
"-O3 -mfpmath=sse" BROKEN
"-O2" FIXED

Can you test "-O2 -mfpmath=sse"?

[Comment 2 shade266 2005-01-11 19:58:15 UTC]

The initial test included: "-O3 -mfpmath=sse"-which was unsuccessful in compiling.

Second test included : "-02 -mfpmath=sse" - resulting again ina an unsuccessful compile.

Third test includes: ="-O2 -march=athlon-xp -mcpu=athlon-xp -mmmx -msse -funroll-loops -frerun-cse-after-loop -fomit-frame-pointer -pipe" -resulting in successful compile of xorg-x11 everytime.

[Comment 3 Donnie Berkholz (RETIRED) 2005-01-11 22:22:35 UTC]

Conclusion being -mfpmath=sse doesn't work with gcc 3.3.4. Care to test gcc-3.4.x (in other words, latest ~x86)?

[Comment 4 shade266 2005-01-13 21:27:15 UTC]

An update to the testing of gcc 3.4.3 includes; the inability to create a link to /usr/portage/profiles/default-linux/x86/2004.3 make.profile, can only login using xdm and have only the option of the Fail-Safe session to work from.

Also, my profile is not being updated even with repeated attempts to do so. Currently, my bash profile for non-root user; amexus@localhost ~ $ and for root; localhost amexus #.  I am encoutering an error when trying to emerge sync:  !!! /etc/make.profile is not a symlink and will probably prevent most merges.
!!! It should point into a profile within /usr/portage/profiles/
!!! (You can safely ignore this message when syncing. It's harmless.)


!!! ARCH is not set... Are you missing the /etc/make.profile symlink?
!!! Is the symlink correct? Is your portage tree complete?

I have tried to correct this by pointing the link to the specified profiles suggested by the error output to no avail.

[Comment 5 Donnie Berkholz (RETIRED) 2005-01-13 21:39:26 UTC]

`ln -s /usr/portage/profiles/default-linux/x86/2004.3 /etc/make.profile` should do the trick. Alternately, `ln -s ../usr/portage/profiles/default-linux/x86/2004.3 /etc/make.profile` if you prefer relative links.

[Comment 6 shade266 2005-02-09 17:28:06 UTC]

Following the testing of the CFLAGS and gcc; i had a royaly screwed system and the last suggestion posted by Donnie didn't resolve the matter either.

Fortunately the errors were directly my fault and my own error. I didn't pay any attention to the profile my link was pointing to and I unmerged the gcc version I had running initially. But there is more i will update the bug with. As of late i have been pretty busy and haven't had time to update the bug progress.

[Comment 7 shade266 2005-02-26 07:52:46 UTC]

This bug has not been encountered following 5 test compilations and installs. Possibly I have been out so much I haven't been up to date with patches and code changes etc. 
In conclusion, I have not been able to re-create the bug/issue following 5 attempts to do so. This bug is closed and will be re-opened if required.
