r142058 | atrick | 2011-10-14 23:19:55 -0700 (Fri, 14 Oct 2011) | 7 lines Fix SCEVExpander assert during LSR: "argument of incompatible type". Just because we're dealing with a GEP doesn't mean we can assert the SCEV has a pointer type. The fix is simply to ignore the SCEV pointer type, which we really didn't need. Fixes PR11138 webkit crash. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_30@142094 91177308-0d34-0410-b5e6-96231b3b80d8

Reapply r141870, SCEV expansion of post-inc.

2011-10-13T21:55:29Z

Speculatively reapply to see if this test case still crashes on linux. I may have fixed it in my last checkin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141895 91177308-0d34-0410-b5e6-96231b3b80d8

Revert r141870. The test case crashes on linux with data corruption. A deeper issue was exposed.

LSR: Reuse the post-inc expansion of expressions.

2011-10-13T17:31:47Z

This avoids unnecessary expansion of expressions and allows the SCEV expander to work on expression DAGs, not just trees. Fixes PR11090. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141870 91177308-0d34-0410-b5e6-96231b3b80d8

Removed colons from some target datalayout strings in test, since they don't match the required format.

Unit test for LSR phi reuse in r141442.

LSR should avoid redundant edge splitting.

2011-10-04T03:50:44Z

This handles the case in which LSR rewrites an IV user that is a phi and splits critical edges originating from a switch. Fixes LSR is not splitting edges "nicely" git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141059 91177308-0d34-0410-b5e6-96231b3b80d8

Stop emitting instructions with the name "tmp" they eat up memory and have to be uniqued, without any benefit.

If someone prefers %tmp42 to %42, run instnamer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140634 91177308-0d34-0410-b5e6-96231b3b80d8

LSR, correct fix for rdar://9786536. Silly casting bug.

2011-07-21T01:45:54Z

LSR must sometimes sign-extend before generating double constants.
