Evan Cheng	3927f438b5	Revert 67132. This is breaking some objective-c apps. ... Also fixes SDISel so it *does not* force promote return value if the function is not marked signext / zeroext. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67701 91177308-0d34-0410-b5e6-96231b3b80d8	2009-03-25 20:20:11 +00:00
Evan Cheng	fc0b80d974	Fix PR3784: If the source of a phi comes from a bb ended with an invoke, make sure the copy is inserted before the try range (unless it's used as an input to the invoke, then insert it after the last use), not at the end of the bb. ... Also re-apply r66140 which was disabled as a workaround. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66976 91177308-0d34-0410-b5e6-96231b3b80d8	2009-03-13 22:59:14 +00:00
Duncan Sands	58256f83c8	Revert commit 66140 since it caused several failures ... in the Ada testcase. Reverting this only covers up the real problem, which is a nasty conceptual difficulty in the phi elimination pass: when eliminating phi nodes in landing pads, the register copies need to come before the invoke, not at the end of the basic block which is too late... See PR3784. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66826 91177308-0d34-0410-b5e6-96231b3b80d8	2009-03-12 21:13:42 +00:00
Evan Cheng	6fb8f421ee	Do not split edges to EH landing pads. It will cause code size explosion. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66140 91177308-0d34-0410-b5e6-96231b3b80d8	2009-03-05 06:31:26 +00:00
