* Skip functions that return multiple values.Devang Patel2008-03-111-0/+3
| | | | llvm-svn: 48233
* Become multiple return value aware.Devang Patel2008-03-111-1/+5
| | | | | | | Right now, the pass does not optimize tail recursions involving multiple return values. llvm-svn: 48228
* Add TODO reminder.Devang Patel2008-03-111-0/+1
| | | | llvm-svn: 48227
* Initial multiple return values support.Devang Patel2008-03-111-19/+95
| | | | llvm-svn: 48210
* Restore optimization that merges blocks when inline function Devang Patel2008-03-101-6/+24
| | | | | | has single return value. llvm-svn: 48162

* Fix some compilation errors on msvc:Ted Kremenek2008-03-091-0/+1
| | | | | | | | | - "Redefinition of I" (iterator masks previous definition) - include missing header file Patch by Argiris Kirtzidis! llvm-svn: 48115
* And again.Nick Lewycky2008-03-091-1/+2

* Braces belong here. No functionality change.Nick Lewycky2008-03-091-1/+2
| | | | llvm-svn: 48111
* SCCP also needs to be taught to follow unwind_toNick Lewycky2008-03-091-0/+4
| | | | llvm-svn: 48109
* Don't eliminate blocks that are only reachable by unwind_to.Nick Lewycky2008-03-091-2/+8
| | | | llvm-svn: 48106
* Firstly, having a BranchInst isn't exclusive with having an unwind_to.Nick Lewycky2008-03-091-5/+8
| | | | | | | Secondly, we have to check whether the branch is actually pointing to the block with the unwind in it. We could have gotten here because of the unwind_to alone. llvm-svn: 48099
* A BB that unwind_to an "unwind" inst is that same as one that doesn't unwind_toNick Lewycky2008-03-091-1/+4

* Update the block cloner which fixes bugpoint on code using unwind_to (phew!)Nick Lewycky2008-03-096-14/+43
| | | | | | and also update the cloning interface's major user, the loop optimizations. llvm-svn: 48088
* Update the inliner and simplifycfg to handle unwind_to.Nick Lewycky2008-03-092-1/+22
| | | | llvm-svn: 48086
* Two things. Preserve the unwind_to when splitting a BB.Nick Lewycky2008-03-091-0/+1
| | | | | | | Add the ability to remove just one instance of a BB from a phi node. This fixes the compile error in the tree now. llvm-svn: 48085
