* TableGen'erate mapping physical registers to encoding values.Jim Grosbach2012-05-15
| | | | | | | | | | | Many targets always use the same bitwise encoding value for physical registers in all (or most) instructions. Add this mapping to the .td files and TableGen'erate the information and expose an accessor in MCRegisterInfo. patch by Tom Stellard. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156829 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove the expensive BitVector::operator~().Jakob Stoklund Olesen2012-05-14
| | | | | | | Returning a temporary BitVector is very expensive. If you must, create the temporary explicitly: Use BitVector(A).flip() instead of ~A. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156768 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove BitVector binops.Jakob Stoklund Olesen2012-05-14
| | | | | | | | | | | These operators were crazy slow, calling malloc to return a temporary result. At the same time, they look very innocent when used in code. If you need temporary BitVectors to compute your thing, create them explicitly, and use the inplace logical operators. This makes the high cost explicit in the code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156767 91177308-0d34-0410-b5e6-96231b3b80d8

* Recommited r156374 with critical fixes in BitcodeReader/Writer:Stepan Dyatkovskiy2012-05-12
| | | | | | | | | | Ordinary patch for PR1255. Added new case-ranges orientated methods for adding/removing cases in SwitchInst. After this patch cases will internally representated as ConstantArray-s instead of ConstantInt, externally cases wrapped within the ConstantRangesSet object. Old methods of SwitchInst are also works well, but marked as deprecated. So on this stage we have no side effects except that I added support for case ranges in BitcodeReader/Writer, of course test for Bitcode is also added. Old "switch" format is also supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156704 91177308-0d34-0410-b5e6-96231b3b80d8

* Add an MF argument to TRI::getPointerRegClass() and TII::getRegClass().Jakob Stoklund Olesen2012-05-07
| | | | | | | | | | | | | The getPointerRegClass() hook can return register classes that depend on the calling convention of the current function (ptr_rc_tailcall). So far, we have been able to infer the calling convention from the subtarget alone, but as we add support for multiple calling conventions per target, that no longer works.

* Rename the Region::block_iterator to Region::block_node_iterator, andChandler Carruth2012-05-04
| | | | | | | | | | | | | | | | | | | | | | | | add a new Region::block_iterator which actually iterates over the basic blocks of the region. The old iterator, now call 'block_node_iterator' iterates over RegionNodes which contain a single basic block. This works well with the GraphTraits-based iterator design, however most users actually want an iterator over the BasicBlocks inside these RegionNodes. Now the 'block_iterator' is a wrapper which exposes exactly this interface. Internally it uses the block_node_iterator to walk all nodes which are single basic blocks, but transparently unwraps the basic block to make user code simpler. While this patch is a bit of a wash, most of the updates are to internal users, not external users of the RegionInfo. I have an accompanying patch to Polly that is a strict simplification of every user of this interface, and I'm working on a pass that also wants the same simplified interface. This patch alone should have no functional impact. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156202 91177308-0d34-0410-b5e6-96231b3b80d8

* Factor the computation of input and output sets into a public interfaceChandler Carruth2012-05-04
| | | | | | | | | | | | | | | | of the CodeExtractor utility. This allows speculatively computing input and output sets to measure the likely size impact of the code extraction. These sets cannot be reused sadly -- we mutate the function prior to forming the final sets used by the actual extraction. The interface has been revamped slightly to make it easier to use correctly by making the interface const and sinking the computation of the number of exit blocks into the full extraction function and away from the rest of this logic which just computed two output parameters. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156168 91177308-0d34-0410-b5e6-96231b3b80d8
