| | | | | | | | | | instruction flag, and use the flag along with a virtual member function hook for targets to override if there are instructions that are only trivially rematerializable with specific operands (i.e. constant pool loads). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37728 91177308-0d34-0410-b5e6-96231b3b80d8
* Replace M_REMATERIALIZIBLE and the newly-added isOtherReMaterializableLoadDan Gohman2007-06-191-12/+4
| | | | | | | | | | | with a general target hook to identify rematerializable instructions. Some instructions are only rematerializable with specific operands, such as loads from constant pools, while others are always rematerializable. This hook allows both to be identified as being rematerializable with the same mechanism. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37644 91177308-0d34-0410-b5e6-96231b3b80d8
