Evan Cheng	7e4217176a	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. llvm-svn: 67701	2009-03-25 20:20:11 +00:00
Evan Cheng	cda58e565f	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. llvm-svn: 66976	2009-03-13 22:59:14 +00:00
Duncan Sands	968939fca2	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. llvm-svn: 66826	2009-03-12 21:13:42 +00:00
Evan Cheng	24c138a1cd	Do not split edges to EH landing pads. It will cause code size explosion. ... llvm-svn: 66140	2009-03-05 06:31:26 +00:00
