Hal Finkel 9364c269c6 Account for scalarization costs in BasicTTI::getMemoryOpCost for extending vector loads ... When a vector type legalizes to a larger vector type, and the target does not support the associated extending load (or truncating store), then legalization will scalarize the load (or store) resulting in an associated scalarization cost. BasicTTI::getMemoryOpCost needs to account for this. Between this, and r205487, PowerPC on the P7 with VSX enabled shows: MultiSource/Benchmarks/PAQ8p/paq8p: 43% speedup SingleSource/Benchmarks/BenchmarkGame/puzzle: 51% speedup SingleSource/UnitTests/Vectorizer/gcc-loops 28% speedup (some of these are new; some of these, such as PAQ8p, just reverse regressions that VSX support would trigger) llvm-svn: 205495		2014-04-03 00:53:59 +00:00
