* Fix PPC branch selection for counter-based branchesHal Finkel2013-05-211-3/+9
| | | | | | | | | | | | Although I had added some support for the BDZ/BDNZ branches into the selector (in r158204), I had not correctly adjusted the condition at the top of the loop. As a result, these branches were still essentially unsupported. This fixes PR16086. Unfortunately, any test case would be very large (because it would need to force the loop backedge to exceed the range of the 16-bit immediate). llvm-svn: 182385

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-3/+3
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131
* Add the PPCCTRLoops pass: a PPC machine-code-level optimization pass to form ↵Hal Finkel2012-06-081-12/+24
| | | | | | | | | | CTR-based loop branching code. This pass is derived from the Hexagon HardwareLoops pass. The only significant enhancement over the Hexagon pass is that PPCCTRLoops will also attempt to delete the replaced add and compare operations if they are no longer otherwise used. Also, invalid preheader DebugLoc is not used. llvm-svn: 158204

* Add new shorter predicates for testing machine operands for various types: Chris Lattner2007-12-301-1/+1
| | | | | | | | | | | | e.g. MO.isMBB() instead of MO.isMachineBasicBlock(). I don't plan on switching everything over, so new clients should just start using the shorter names. Remove old long accessors, switching everything over to use the short accessor: getMachineBasicBlock() -> getMBB(), getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc. llvm-svn: 45464

* Rewrite the branch selector to be correct in the face of large functions.Chris Lattner2006-11-181-84/+101
| | | | | | | | | | | | | | | The algorithm it used before wasn't 100% correct, we now use an iterative expansion model. This fixes assembler errors when compiling 403.gcc with tail merging enabled. Change the way the branch selector works overall: Now, the isel generates PPC::BCC instructions (as it used to) directly, and these BCC instructions are emitted to the output or jitted directly if branches don't need expansion. Only if branches need expansion are instructions rewritten and created. This should make branch select faster, and eliminates the Bxx instructions from the .td file. llvm-svn: 31837
* convert PPC::BCC to use the 'pred' operand instead of separate predicateChris Lattner2006-11-171-2/+2
