This specifically penalizes the insertelement and extractelement operations for the performance hit that will occur on PowerPC processors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174725 91177308-0d34-0410-b5e6-96231b3b80d8 2013-01-25T23:05:59Z Hal Finkel hfinkel@anl.gov 2013-01-25T23:05:59Z urn:sha1:a8b289b70d5ef416608bb71a874b8b4fe80158e1 This provides a place to add customized operation cost information and control some other target-specific IR-level transformations. The only non-trivial logic in this checkin assigns a higher cost to unaligned loads and stores (covered by the included test case). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173520 91177308-0d34-0410-b5e6-96231b3b80d8
