Description Matze Braun 2003-02-28 05:03:57 UTC

I'm using a pentium optimized (stable x86) gentoo system (CFLAGS:
-march=pentium4 -O3 -pipe). I tried valgrind 1.0.4 and valgrind 1.9.3 but they
always fail. 

Reproducible: Always
Steps to Reproduce:
1. Install valgrind on a pentium4 compiled system
2. do "valgrind /usr/bin/ls"
Actual Results:

==28516== This may be because the functionality is hard to implement,
==28516== or because no reasonable program would behave this way,
==28516== or because nobody has yet needed it.  In any case, let me know
==28516== (jseward@acm.org) and/or try to work around the problem, if you can.
==28516==
==28516== Valgrind has to exit now.  Sorry.  Bye!

what version of gcc ?
some versions are known to cause issues with 'arch=pentium4' with relation to
glibc and other packages

Comment 2 Matze Braun 2003-02-28 06:22:30 UTC

gcc 3.2.1-r6

Right, check the latest make.conf.  Known issue with gcc developers, you will
just have to learn to live with -march=pentium3.

This needs to be fixed gcc side :(

Comment 5 witr 2003-08-06 08:35:30 UTC

Please be advised that the ebuild in bug 24640 resolves this issue.  I have these flags:  -O2 -march=pentium3 -mcpu=pentium4 -mfpmath=sse -finline-functions -fomit-frame-pointer -pipe, and I'm using gcc-3.2.3-r1 and glibc-2.3.2-r1.  With the valgrind-1.9.6 version I get the reported error.  With the valgrind-20030716 version everything seems to run correctly.
