Summary: 86 new failures in the g++ testsuite last night
GCC 4.1 seems to sometimes generate inefficient code when doing
structure assignments directly when compiling for MIPS1. When assigning
to structure members manually, it generates regular lw/sw sequences.
When assigning to the structure, you instead get lwl/lwr and swl/swr
pairs (for no reason,

Note we do simplify this later on after PRE/FRE as we sink the a2 into the
other basic block and then VRP

Code works with no optimization, and after removing the assigned goto's it
works with optimization. I'm on a dual opteron system with
GNU Fortran 95 (GCC) 4.1.2 (Gentoo 4.1.2)
When compiling gcc, I used: CFLAGS=-O2 -march=opteron -pipe
-fomit-frame-pointer
The old g77 worked on this code.

Can you try gfortran from the 4.2 branch or from trunk? You
can get a binary package of trunk from the gfortran wiki.
Can attach the code to the bug report or a URL to the code?
Otherwise, we can't try to reproduce
--- Comment #9 from tkoenig at gcc dot gnu dot org 2007-02-28 22:04 ---
In principle, this is easy to fix: Use
an unsigned variable for u. In practice, this
means we have to delve into iparm.m4. Yuck :-)
I'll look at this, but if somebody else has a
good suggestion, please go ahead.
Now that gcc understands OpenMP directives, it would be really cool if the
member functions of the std::valarray class could be annotated. Most of
the member functions have loops over all elements that are trivially parallel
and that could benefit from OpenMP autoparallelization. I am fairly sure
