* MC: Don't assume incoming StringRef's are null terminated.Will Dietz2013-10-131-3/+1
| | | | | | | | | | This can happen when processing command line arguments, which are often stored as std::string's and later turned into StringRef's via std::string::data(). Unfortunately this is not guaranteed to return a null-terminated string until C++11, causing breakage on platforms that don't do this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192558 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix X86 subtarget to not overwrite the autodetected features by calling ↵Craig Topper2013-09-181-0/+5
| | | | | | InitMCProcessorInfo right after detecting them. Instead add a new function that only updates the scheduling model and call that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190919 91177308-0d34-0410-b5e6-96231b3b80d8
* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-2/+2
| | | | | | | | | | | | | | | | | 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. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

* Replaced ReInitMCSubtargetInfo with InitMCProcessor.Andrew Trick2012-09-181-14/+15
| | | | | | | | Now where we used to call ReInitMCSubtargetInfo, we actually recompute the same information as InitMCSubtargetInfo instead of only setting the feature bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164105 91177308-0d34-0410-b5e6-96231b3b80d8

* I'm introducing a new machine model to simultaneously allow simpleAndrew Trick2012-07-071-14/+19
| | | | | | | | | | | | | | | | | | | | | | | subtarget CPU descriptions and support new features of MachineScheduler. MachineModel has three categories of data: 1) Basic properties for coarse grained instruction cost model. 2) Scheduler Read/Write resources for simple per-opcode and operand cost model (TBD). 3) Instruction itineraties for detailed per-cycle reservation tables. These will all live side-by-side. Any subtarget can use any combination of them. Instruction itineraries will not change in the near term. In the long run, I expect them to only be relevant for in-order VLIW machines that have complex contraints and require a precise scheduling/bundling model. Once itineraries are only actively used by VLIW-ish targets, they could be replaced by something more appropriate for those targets. This tablegen backend rewrite sets things up for introducing MachineModel type #2: per opcode/operand cost model. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159891 91177308-0d34-0410-b5e6-96231b3b80d8

* - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfoEvan Cheng2011-07-111-8/+11
| | | | | | | | | | | | | and MCSubtargetInfo. - Added methods to update subtarget features (used when targets automatically detect subtarget features or switch modes). - Teach X86Subtarget to update MCSubtargetInfo features bits since the MCSubtargetInfo layer can be shared with other modules. - These fixes .code 16 / .code 32 support since mode switch is updated in MCSubtargetInfo so MC code emitter can do the right thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134884 91177308-0d34-0410-b5e6-96231b3b80d8
