[LLVMdev] Turning on/off instruction extensions

Hi,

There are a *lot* of changes (around 15000 commits if I recall Chris'
keynote) between 2.9 and 3.0/trunk. It does sound like you're on a lost
cause at the moment - you can't ignore those patching errors.

Cheers,

James

Sorry, the previous mail was unreadable:

I tried to apply the patch to llvm 2.9 (not the trunk) but it shows a lot of
"... hunk FAILED -- saving rejects to file ...". Is it safe to ignore
these
errors? Is it impossible to apply this patch to LLVM 2.9? Do you have a
version of the vectorizer patch compatible with LLVM and Clang 2.9?

Right now I cannot switch to the trunk version.

Thanks in advance,
Pablo
