* Update SetVector to rely on the underlying set's insert to return a ↵David Blaikie2014-11-191-4/+4
| | | | | | | | | | | | | pair<iterator, bool> This is to be consistent with StringSet and ultimately with the standard library's associative container insert function. This lead to updating SmallSet::insert to return pair<iterator, bool>, and then to update SmallPtrSet::insert to return pair<iterator, bool>, and then to update all the existing users of those functions... llvm-svn: 222334

* [C++11] Replace llvm::next and llvm::prior with std::next and std::prev.Benjamin Kramer2014-03-021-2/+2
| | | | | | Remove the old functions. llvm-svn: 202636
* Move an assertion so it doesn't dereference end().Jakob Stoklund Olesen2013-01-041-4/+3
| | | | | | The R600 target has test cases that exercises this code. llvm-svn: 171538
* Use the new MI bundling API in MachineInstrBundle itself.Jakob Stoklund Olesen2012-12-131-4/+5
| | | | | | | The new API is higher level than just manipulating the bundle flags directly, and the setIsInsideBundle() function will disappear soon. llvm-svn: 170159
* 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
* Fix physical register liveness calculations:Tim Northover2012-11-201-2/+4
| | | | | | | + Take account of clobbers + Give outputs priority over inputs since they happen later. llvm-svn: 168360
* Increase the static sizes of some SmallSets. finalizeBundle() is very ↵Michael Ilseman2012-09-171-4/+4

* Add an analyzePhysReg() function to MachineOperandIteratorBase that analyses ↵James Molloy2012-09-121-2/+52
| | | | | | | | an instruction's use of a physical register, analogous to analyzeVirtReg. Rename RegInfo to VirtRegInfo so as not to be confused with the new PhysRegInfo. llvm-svn: 163694
* Switch all register list clients to the new MC*Iterator interface.Jakob Stoklund Olesen2012-06-011-2/+2
| | | | | | | | | | | | | No functional change intended. Sorry for the churn. The iterator classes are supposed to help avoid giant commits like this one in the future. The TableGen-produced register lists are getting quite large, and it may be necessary to change the table representation. This makes it possible to do so without changing all clients (again). llvm-svn: 157854
* Avoid finalizeBundles infinite looping.Evan Cheng2012-03-061-0/+2

* Convert more GenRegisterInfo tables from unsigned to uint16_t to reduce ↵Craig Topper2012-03-051-1/+1
| | | | | | static data size. llvm-svn: 152016
* Add an analyzeVirtReg() function.Jakob Stoklund Olesen2012-02-291-0/+33
| | | | | | | | | | | | | | This function does more or less the same as MI::readsWritesVirtualRegister(), but it supports bundles as well. It also determines if any constraint requires reading and writing operands to use the same register. Most clients want to know. Use the more modern MO.readsReg() instead of trying to sort out undefs and partial redefines. Stop supporting the extra full <imp-def> operand as an alternative to <def,undef> sub-register defines. llvm-svn: 151690
* Codegen pass definition cleanup. No functionality.Andrew Trick2012-02-081-8/+2
| | | | | | | | | | | | | Moving toward a uniform style of pass definition to allow easier target configuration. Globally declare Pass ID. Globally declare pass initializer. Use INITIALIZE_PASS consistently. Add a call to the initializer from CodeGen.cpp. Remove redundant "createPass" functions and "getPassName" methods. While cleaning up declarations, cleaned up comments (sorry for large diff). llvm-svn: 150100
* More bundle related API additions.Evan Cheng2012-01-191-1/+52

* Enhance finalizeBundle to return end of bundle iterator because it makes sense.Evan Cheng2012-01-191-3/+6
| | | | llvm-svn: 148462
* - Slight change to finalizeBundle() interface. LastMI is not exclusive (pointingEvan Cheng2012-01-191-3/+18
| | | | | | | | | | | to instruction right after the last instruction in the bundle. - Add a finalizeBundle() variant that doesn't specify LastMI. Instead, the code will find the last instruction in the bundle by following the 'InsideBundle' marker. This is useful in case bundles are formed early (i.e. during MI scheduling) but finalized later (i.e. after register allocator has finished rewriting virtual registers with physical registers). llvm-svn: 148444
* Rename Finalizebundle to finalizeBundle to conform to coding guideline.Evan Cheng2012-01-191-2/+2
| | | | llvm-svn: 148440
* - Add MachineInstrBundle.h and MachineInstrBundle.cpp. This includes a functionEvan Cheng2011-12-141-0/+180
to finalize MI bundles (i.e. add BUNDLE instruction and computing register def and use lists of the BUNDLE instruction) and a pass to unpack bundles. - Teach more of MachineBasic and MachineInstr methods to be bundle aware. - Switch Thumb2 IT block to MI bundles and delete the hazard recognizer hack to prevent IT blocks from being broken apart. llvm-svn: 146542
