The mipsel-linux target had been clean for C and C++ (except for
mayalias-[23].c) at r129657:
http://gcc.gnu.org/ml/gcc-testresults/2007-10/msg01332.html
g++.dg/tree-ssa/ivopts-1.C started failing by r129727:
http://gcc.gnu.org/ml/gcc-testresults/2007-10/msg01385.html
And gcc.dg/tree-ssa/pr33723.c by r129776:
http://gcc.gnu.org/ml/gcc-testresults/2007-10/msg01439.html
It appears that these are probably missed optimizations, but it would be
nice to understand why they are failing on MIPS and not on say x86_64:
