Dan Gohman	6fedb3c401	Don't convert objc_retainAutoreleasedReturnValue to objc_retain if it ... is retaining the return value of an invoke that it immediately follows. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153344 91177308-0d34-0410-b5e6-96231b3b80d8	2012-03-23 18:09:00 +00:00
Dan Gohman	fbab4a8c8a	It's not possible to insert code immediately after an invoke in the ... same basic block, and it's not safe to insert code in the successor blocks if the edges are critical edges. Splitting those edges is possible, but undesirable, especially on the unwind side. Instead, make the bottom-up code motion to consider invokes to be part of their successor blocks, rather than part of their parent blocks, so that it doesn't push code past them and onto the edges. This fixes PR12307. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153343 91177308-0d34-0410-b5e6-96231b3b80d8	2012-03-23 17:47:54 +00:00
Dan Gohman	8b11fdd8bb	When an invoke is marked with metadata indicating its unwind edge ... should be ignored by ARC optimization, don't insert new ARC runtime calls in the unwind destination. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152748 91177308-0d34-0410-b5e6-96231b3b80d8	2012-03-14 23:05:06 +00:00
Bill Wendling	ab98f9d155	Update more tests to the new EH scheme. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138894 91177308-0d34-0410-b5e6-96231b3b80d8	2011-08-31 21:04:11 +00:00
Dan Gohman	0860d0ba2f	Fix ARCOpt to insert releases on both successors of an invoke rather ... than trying to insert them immediately after the invoke. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133188 91177308-0d34-0410-b5e6-96231b3b80d8	2011-06-16 20:57:14 +00:00
