Duncan Sands	d3e07c9d09	Tweak the fix for PR3784: be less sensitive about just ... how invokes are set up. The fix could be disturbed by register copies coming after the EH_LABEL, and also didn't behave quite right when it was the invoke result that was used in a phi node. Also (see new testcase) fix another phi elimination bug while there: register copies in the landing pad need to come after the EH_LABEL, because that's where execution branches to when unwinding. If they come before the EH_LABEL then they will never be executed... Also tweak the original testcase so it doesn't use a no-longer existing counter. The accumulated phi elimination changes fix two of seven Ada testsuite failures that turned up after landing pad critical edge splitting was turned off. So there's probably more to come. llvm-svn: 67049	2009-03-16 19:58:38 +00:00
Evan Cheng	94419d6fdd	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
