Raul E. Silvera 6df2b69098 When analyzing vectors of element type that require legalization, ... the legalization cost must be included to get an accurate estimation of the total cost of the scalarized vector. The inaccurate cost triggered unprofitable SLP vectorization on 32-bit X86. Summary: Include legalization overhead when computing scalarization cost Reviewers: hfinkel, nadav CC: chandlerc, rnk, llvm-commits Differential Revision: http://llvm-reviews.chandlerc.com/D2992 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203509 91177308-0d34-0410-b5e6-96231b3b80d8		2014-03-10 22:59:13 +00:00

arith.ll	CostModel: increase the default cost of supported floating point operations from 1 to two. Fixed a few tests that changes because now the cost of one insert + a vector operation on two doubles is lower than two scalar operations on doubles.	2013-04-12 21:15:03 +00:00
