According to Shark, my application will run much faster and happier
if I turn on "-falign-loops=32" (it's catching a tight Altivec loop
whose beginning instruction is not 32-byte aligned). So I added the
flag to the "Other C++ flags" in my project's Target Info window. I see
the flag appear in the command line portion of the Build window for
each source file after I compile, but when I run Shark against the new
build my loop is still not aligned!
I've tried various optimation settings (-O0, -O3, -Os), and tried
Deployment vs. Development builds but can't seem to see any change in
the alignment (or lack thereof). Im running XCode 1.5, with gcc 3.3.
What else do I need to do to change the alignment?
TIA
