Okay. Like Jeff said, he's a good channel to get the patches applied.
libsystem hasn't changed much since 1.5, so those patches should basically
just apply like you said.
If you have x86-specific changes I can take a look. The X86 backend has
changed *significantly* in the last couple of releases, and will be making
another big leap in the next couple of weeks.
Evan Cheng is also planning on adding vector SSE support to the X86
backend in the next couple of months: if your compiler is generating
values with packed types, it should automatically take advantage of this
Finally, if you're upgrading to CVS head and using packed types, you might
want to take advantage of the new InsertElement and ExtractElement
instructions that Rob Bocchino added to LLVM:
As usual, if you run into any problems or any mysteries, email llvmdev and
we'd be happy to help! :)
