Dan Gohman	6a1d9eace9	Check in the experimental GEP splitter pass. This pass splits complex GEPs (more than one non-zero index) into simple GEPs (at most one non-zero index). In some simple experiments using this it's not uncommon to see 3% overall code size wins, because it exposes redundancies that can be eliminated, however it's tricky to use because instcombine aggressively undoes the work that this pass does. llvm-svn: 85144	2009-10-26 19:12:14 +00:00

Check in the experimental GEP splitter pass. This pass splits complex

GEPs (more than one non-zero index) into simple GEPs (at most one
non-zero index).  In some simple experiments using this it's not
uncommon to see 3% overall code size wins, because it exposes
redundancies that can be eliminated, however it's tricky to use
because instcombine aggressively undoes the work that this pass does.
