Bill Schmidt 5cd01f74b1 Change some PowerPC PatLeaf definitions to ImmLeaf for fast-isel. ... Using PatLeaf rather than ImmLeaf when defining immediate predicates prevents simple patterns using those predicates from being recognized for fast instruction selection. This patch replaces the immSExt16 PatLeaf predicate with two ImmLeaf predicates, imm32SExt16 and imm64SExt16, allowing a few more patterns to be recognized (ADDI, ADDIC, MULLI, ADDI8, and ADDIC8). Using the new predicates does not help for LI, LI8, SUBFIC, and SUBFIC8 because these are rejected for other reasons, but I see no reason to retain the PatLeaf predicate. No functional change intended, and thus no test cases yet. This is preliminary work for enabling fast-isel support for PowerPC. When that support is ready, we'll be able to test this function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182510 91177308-0d34-0410-b5e6-96231b3b80d8		2013-05-22 20:09:24 +00:00
