------- 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. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39976
