It's not safe to sink into landing pad BB's. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@64790 91177308-0d34-0410-b5e6-96231b3b80d8 2009-02-17T19:32:45Z Tanya Lattner tonic@nondot.org 2009-02-17T19:32:45Z urn:sha1:3bf2b5ea6fe27c2528354f40dab3ed39bdb35f89 Fix pr3571: If stride is a value defined by an instruction, make sure it dominates the loop preheader. When IV users are strength reduced, the stride is inserted into the preheader. It could create a use before def situation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@64789 91177308-0d34-0410-b5e6-96231b3b80d8 2009-02-17T19:21:47Z Tanya Lattner tonic@nondot.org 2009-02-17T19:21:47Z urn:sha1:8396e7671f88c28f9edfe92a53a60c3abb5b64d3 git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@64785 91177308-0d34-0410-b5e6-96231b3b80d8 2009-02-17T19:01:36Z Tanya Lattner tonic@nondot.org 2009-02-17T19:01:36Z urn:sha1:9114c43bee82b9992fe1fcb12d58a8b2e3a474b6 Make a transformation added in 63266 a bit less aggressive. It was transforming (x&y)==y to (x&y)!=0 in the case where y is variable and known to have at most one bit set (e.g. z&1). This is not correct; the expressions are not equivalent when y==0. I believe this patch salvages what can be salvaged, including all the cases in bt.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@64782 91177308-0d34-0410-b5e6-96231b3b80d8 2009-02-14T01:14:49Z Tanya Lattner tonic@nondot.org 2009-02-14T01:14:49Z urn:sha1:606531328717459521c87b6ac091720c1e763365 Don't try to set an EFLAGS operand to dead if no instruction was created. This fixes a bug introduced by r61215. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@64524 91177308-0d34-0410-b5e6-96231b3b80d8 2009-02-14T01:04:03Z Tanya Lattner tonic@nondot.org 2009-02-14T01:04:03Z urn:sha1:3400fc0434bc7651d205f83bc8d71b943f1059b5 Fix a nasty bug (PR3550) where the inline pass could incorrectly mark calls with the tail marker when inlining them through an invoke. Patch, testcase, and perfect analysis by Jay Foad! git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@64520 91177308-0d34-0410-b5e6-96231b3b80d8 2009-02-14T00:59:47Z Tanya Lattner tonic@nondot.org 2009-02-14T00:59:47Z urn:sha1:6a64c0bc1e7ac9459f769d1cca79bb13ab2fb452 Turns out AnalyzeBranch can modify the mbb being analyzed. This is a nasty suprise to some callers, e.g. register coalescer. For now, add an parameter that tells AnalyzeBranch whether it's safe to modify the mbb. A better solution is out there, but I don't have time to deal with it right now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@64518 91177308-0d34-0410-b5e6-96231b3b80d8 2009-02-14T00:57:30Z Tanya Lattner tonic@nondot.org 2009-02-14T00:57:30Z urn:sha1:67a8eaa03b0a0fb119d7ac94b49969ad8b6ccbe9 Fix PR 3471, and some cleanups. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@64517 91177308-0d34-0410-b5e6-96231b3b80d8 2009-02-13T23:53:40Z Tanya Lattner tonic@nondot.org 2009-02-13T23:53:40Z urn:sha1:c1a60e850e9f8bfe2a4cd6cc8774ca34b35cbdc6 Fix PR3486. Fix a bug in code that manually patch physical register live interval after its sub-register is coalesced with a virtual register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@64509 91177308-0d34-0410-b5e6-96231b3b80d8 2009-02-13T23:52:54Z Tanya Lattner tonic@nondot.org 2009-02-13T23:52:54Z urn:sha1:93639fb5cda4ccee74cc605ca4f8bf98b59fc163 Pre-alloc splitting needs to be more careful to avoid inserting spills/restores between call frame setup/restore points. Unfortunately, this regresses code size a bit, but at least it's correct now! git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@64508 91177308-0d34-0410-b5e6-96231b3b80d8
