* Fix bug: CodeExtractor/2004-03-17-MissedLiveIns.llChris Lattner2004-03-181-0/+5
| | | | | | | With this fix we now successfully extract all 149 loops from 256.bzip2 without crashing or miscompiling the program! llvm-svn: 12493
* Fix CodeExtractor/2004-03-17-UpdatePHIsOutsideRegion.llChris Lattner2004-03-181-0/+13

* Seriously simplify and correct the PHI node handling code.Chris Lattner2004-03-181-162/+28

* Fix CodeExtractor/2004-03-17-OutputMismatch.llChris Lattner2004-03-181-3/+7

* Fix several bugs in the extractor:Chris Lattner2004-03-181-45/+52
| | | | | | | | | | | | 1. Names were not put on the new arguments created (ok, this just helps sanity :) 2. Fix outgoing pointer values 3. Do not insert stores for values that had not been computed 4. Fix some wierd problems with the outset calculation This fixes CodeExtractor/2004-03-14-DominanceProblem.ll, making the extractor work on at least one simple case! llvm-svn: 12484
* Prune #includes, moving the module interface to the front. Note that thisChris Lattner2004-03-181-2/+1
| | | | | | | exposed the fact that the header was not self-contained. There is a reason we do things :) llvm-svn: 12481
* Mostly cosmetic improvements. Do fix the bug where a global value was ↵Chris Lattner2004-03-151-35/+23

* Assert that input blocks meet the invariants we expectChris Lattner2004-03-151-42/+38
| | | | | | | | Simplify the input/output finder. All elements of a basic block are instructions. Any used arguments are also inputs. An instruction can only be used by another instruction. llvm-svn: 12405
* No correctness fixes here, just minor qoi fixes:Chris Lattner2004-03-141-30/+26
| | | | | | | | | | | | | * Don't insert a branch to the switch instruction after the call, just make it a single block. * Insert the new alloca instructions in the entry block of the original function instead of having them execute dynamically * Don't make the default edge of the switch instruction go back to the switch. The loop extractor shouldn't create new loops! * Give meaningful names to the alloca slots and the reload instructions * Some minor code simplifications llvm-svn: 12402
* Simplify code a bit, and fix bug CodeExtractor/2004-03-14-NoSwitchSupport.llChris Lattner2004-03-141-62/+34
| | | | | | | | | | This also implements a two minor improvements: * Don't insert live-out stores IN the region, insert them on the code path that exits the region * If the region is exited to the same block from multiple paths, share the switch statement entry, live-out store code, and the basic block. llvm-svn: 12401
* Simplify the code a bit by making the collection of basic blocks to extractChris Lattner2004-03-141-57/+39
