...y ~3%, timewise. Time spent in oc_enc_frag_sad is reduced from 4.2% to 2.3% and oc_enc_frag_ssd from 1.2% to 1.0%, as reported by Shark. Currently this is only integrated into the Xcode build project and need support for detecting Altivec on platforms other than OS X; on OS X it uses the sysctl hw.vectorunit.

The upside is that it preserves the IR / codegen distinction that we've all grown to love, and does it using a mechanism that is in LLVM terms as old as the hills. No reviewer could argue that. I was imagining a new "target vectorunit = "..."" string in the modules. If you want a different way of doing it for the vector information, I might ask that you change how TargetData works too. :) Nick

However, I'm not familiar with "Target Lowering Interface". Could you explain? I agree. Once we make the codegen accessible to the IR-level passes we need to start talking about
