------- Additional Comments From jakub at gcc dot gnu dot org  2004-11-18 21:15 -------
Could this be applied to gcc-3_4-branch as well?
See http://bugzilla.redhat.com/bugzilla/attachment.cgi?id=106985
for a 3.4 testcase that used to work with GCC 3.3.4, but fails with 3.4 branch
as of a month ago or from today when compiled with
-O -fomit-frame-pointer -m32 -march=i386.
