* Tidy up several unbeseeming casts from pointer to intptr_t.Dan Gohman2008-09-041-1/+1
| | | | llvm-svn: 55779
* Use Loop::block_iterator.Dan Gohman2008-06-221-2/+3
| | | | llvm-svn: 52616

* Change class' public PassInfo variables to by initialized with theDan Gohman2008-05-131-1/+1
| | | | | | | | | | | address of the PassInfo directly instead of calling getPassInfo. This eliminates a bunch of dynamic initializations of static data. Also, fold RegisterPassBase into PassInfo, make a bunch of its data members const, and rearrange some code to initialize data members in constructors instead of using setter member functions. llvm-svn: 51022
* Clean up the use of static and anonymous namespaces. This turned upDan Gohman2008-05-131-4/+4
| | | | | | | several things that were neither in an anonymous namespace nor static but not intended to be global. llvm-svn: 51017
* Remove 'unwinds to' support from mainline. This patch undoes r47802 r47989Nick Lewycky2008-04-251-10/+7
| | | | | | r48047 r48084 r48085 r48086 r48088 r48096 r48099 r48109 and r48123. llvm-svn: 50265
* Move SplitBlockPredecessors out of loopsimplify into BasicBlockUtils.hChris Lattner2008-04-211-107/+14
| | | | | | | | | as a global helper function. At the same type, switch it from taking a vector of predecessors to an arbitrary sequential input. This allows us to switch LoopSimplify to use a SmallVector for various temporary vectors that it passed into SplitBlockPredecessors. llvm-svn: 50020
* Move domtree/frontier updating earlier, allowing us to use it to update phi Chris Lattner2008-04-211-31/+18

* Factor dominator tree and frontier updating into SplitBlockPredecessorsChris Lattner2008-04-211-18/+14

* Update the block cloner which fixes bugpoint on code using unwind_to (phew!)Nick Lewycky2008-03-091-7/+13

* Remove attribution from file headers, per discussion on llvmdev.Chris Lattner2007-12-291-2/+2
| | | | llvm-svn: 45418
* Make LoopInfoBase more generic, in preparation for having MachineLoopInfo. ↵Owen Anderson2007-11-271-4/+4
| | | | | | This involves a small interface change. llvm-svn: 44348
* Fix PR1752 and LoopSimplify/2007-10-28-InvokeCrash.ll: terminators Chris Lattner2007-10-291-4/+6
| | | | | | can have uses too. Wouldn't it be nice if invoke didn't exist? :) llvm-svn: 43426

| | | | | | | | | | DominatorInternals.h in CodeExtractor and LoopSimplify unnecessary. Hartmut, could you confirm that this fixes the issues you were seeing? llvm-svn: 43115
* Fixed linker errors (unresolved externals: split<>(...)) when compiling with ↵Hartmut Kaiser2007-10-171-0/+1

* Update LoopSimplify to require and preserve DominatorTree only.Devang Patel2007-06-081-32/+26

| | | | llvm-svn: 36662
* Use 'static const char' instead of 'static const int'.Devang Patel2007-05-021-2/+2
| | | | | | | Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. llvm-svn: 36652

* Remove ImmediateDominator analysis. The same information can be obtained ↵Owen Anderson2007-04-151-26/+0

* For PR786:Reid Spencer2006-11-021-1/+0
| | | | | | | | | | Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting fall out by removing unused variables. Remaining warnings have to do with unused functions (I didn't want to delete code without review) and unused variables in generated code. Maintainers should clean up the remaining issues when they see them. All changes pass DejaGnu tests and Olden. llvm-svn: 31380
