gcc43-pr29581-tests.patch
Testcases that show this bug even on the trunk (taken from vect-8{5,6,7,8}.c,
removed vector related stuff from it, added -O2 -ftree-loop-linear).
With my preliminary fix for this PR all these seem to be fixed (on a release
only checking gcc), unfortunately with checking enabled I'm getting
tree checking failures like:
error: statement makes a memory store, but has no V_MAY_DEFS nor V_MUST_DEFS
perfecttmp.42 = perfectiv.40_5 + 16;
I called update_stmt, o not sure what I'm still missing.
BTW, with -ftree-loop-linear also fortran forall_1.f90 and scalarize.f90 are
miscompiled, but that problem isn't fixed by my patch, so perhaps there are
other bugs.
