Should we apply the patch from comment 7 before gcc 4.5 branches?

Ben,
Is basic-eh-map.darwin10.ii still failing to compile for you on current gcc
trunk? On x86_64-apple-darwin10, I am finding that
g++-4 basic-eh-map.darwin10.ii -S -m64 -std=c++0x -v -O2 -g

According to...

it is fixed for powerpc-apple-darwin9.

These failures have been eliminated in gcc trunk (4.5.0) since at least
r155368. They may have been eliminated with the VTA merge.

The code being degraded by -fgraphite-identity (when using -ffast-math
-funroll-loops -O3) is in the mqr_m and mqc_m modules. The exact distribution

Does this fix resolve PR42181 as well or is that a different issue with
fgraphite-identity -fstrict-overflow?

Might this be related to PR42181 since it also involves problems with the
-fgraphite-identity -fstrict-overflow?

Interestingly, I get...

The offending optimization for the spectop subroutine at -O2

The miscompiled code in air.f90 is the subroutine SPECTOP. If I pull that
subroutine out into a separate file and compile it at -O3 without
-fgraphite-identity, the remainder of the code can be compiled

The last good build for powerpc-apple-darwin9 on regress was at r157263 so...
r157264
must be the offending commit. Is powerpc64-unknown-linux-gnu still
