[Bug middle-end/39976] [4.5 Regression] Big sixtrack degradation on powerpc 32/64 after revision r146817

[matz at gcc dot gnu dot org]

------- Comment #7 from matz at gcc dot gnu dot org  2009-05-04 14:37 -------
Compile options please.  I can't reproduce it with a powerpc64 compiler
with -O2, neither with -m32 nor -m64, -ffast-math or no -ffast-math.
Also 'gcc -v' can't hurt to make sure our compilers are configured the same.

Hint: I use this command to quickly skim over the situation with labels and
bdnz:
% egrep '^.L|bdnz' thin6d.s

If the bdnz lines always mention the label from a line above it's a single
basic block loop.
