Change tests from "opt %s" to "opt < %s" so that opt doesn't see the input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. llvm-svn: 81537 2009-09-11 20:01:28 +02:00			`; RUN: opt < %s -inline -prune-eh -disable-output`
Move the personality function from LandingPadInst to Function The personality routine currently lives in the LandingPadInst. This isn't desirable because: - All LandingPadInsts in the same function must have the same personality routine. This means that each LandingPadInst beyond the first has an operand which produces no additional information. - There is ongoing work to introduce EH IR constructs other than LandingPadInst. Moving the personality routine off of any one particular Instruction and onto the parent function seems a lot better than have N different places a personality function can sneak onto an exceptional function.

Don't promote asynch EH invokes of nounwind functions to calls If the landingpad of the invoke is using a personality function that catches asynch exceptions, then it can catch a trap. Also add some landingpads to invalid LLVM IR test cases that lack them. Over-the-shoulder reviewed by David Majnemer. llvm-svn: 228782 2015-02-11 02:23:16 +01:00			`cleanup`
