[Sunita Marathe via llvm-commits]

Sunita_Marathe added a comment.

Following are the overall Before/After SPEC2000 size totals resulting from using the heuristics:

Before:
=======

177.mesa total size = 358880
179.art total size = 9259
183.equake total size = 12211
188.ammp total size = 105381
164.gzip total size = 25561
175.vpr total size = 87474
176.gcc total size = 919293
181.mcf total size = 6762
186.crafty total size = 111316
197.parser total size = 63238
253.perlbmk total size = 373439
254.gap total size = 320951
255.vortex total size = 186045
256.bzip2 total size = 18976
300.twolf total size = 145928
Total Size =  2744714

After:
