Subject: Add a comment about overlapping PPC frame offsets
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=6bc99603c0f4fdd15d734851a4343b768f4725a4;p=oota-llvm.git

Add a comment about overlapping PPC frame offsets

I don't think that it is otherwise clear how the overlapping offsets
are processed into distinct spill slots. Comment that this is done
in processFunctionBeforeFrameFinalized.
