Would you please attach the assembler diff:
1) between -m32 -O1 and -m32 -O1 -fforward-propagate
2) between the latter and -m32 -O1 -fforward-propagate -fschedule-insns2?
Thanks.

The bug is actually in target independent code. The code to change_address_1
in adjust_address_1 does nothing if the addr is simple, and this causes the

I can confirm that gcc trunk with the proposed patch can now build xplor-nih at
-O3 (with to resorting to -funroll-loops) and the output code works correctly
now on i686-apple-darwin9. Thanks for fixing

See the analysis in http://gcc.gnu.org/ml/gcc-patches/2009-01/msg00801.html

I really don't think using solaris threads is that well supported anymore. Is

If this is a native build, then GLIBCXX_CHECK_MATH_SUPPORT should have defined

libstdc++ also needs to be built and linked in as dll.
Search mingw archive lists for other examples and approaches.
