* Fixed more best practices, and explicit/implicit style guide issues.Garrison Venn2011-04-101-131/+128

* Reword instructions for running tests on Visual Studio.Oscar Fuentes2011-04-101-1/+3
| | | | | | Suggested by Maël Hörz. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129237 91177308-0d34-0410-b5e6-96231b3b80d8
* Beginning of the Great Exception Handling Rewrite.Bill Wendling2011-04-1010-16/+87
| | | | | | | | | | | | | | * Add a "landing pad" attribute to the BasicBlock. * Modify the bitcode reader and writer to handle said attribute. Later: The verifier will ensure that the landing pad attribute is used in the appropriate manner. I.e., not applied to the entry block, and applied only to basic blocks that are branched to via a `dispatch' instruction. (This is a work-in-progress.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129235 91177308-0d34-0410-b5e6-96231b3b80d8

* Build the Hopfield network incrementally when splitting global live ranges.Jakob Stoklund Olesen2011-04-097-84/+183
| | | | | | | | | It is common for large live ranges to have few basic blocks with register uses and many live-through blocks without any uses. This approach grows the Hopfield network incrementally around the use blocks, completely avoiding checking interference for some through blocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129188 91177308-0d34-0410-b5e6-96231b3b80d8
* Precompute interference for neighbor blocks as long as there is no interference.Jakob Stoklund Olesen2011-04-092-22/+37
