* Add a getBundleEnd() function to go with the existing getBundleStart().Jakob Stoklund Olesen2013-01-091-2/+20
| | | | | | This is easier implemented now that bundle flags are symmetric. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171927 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix physical register liveness calculations:Tim Northover2012-11-201-4/+1
| | | | | | | + Take account of clobbers + Give outputs priority over inputs since they happen later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168360 91177308-0d34-0410-b5e6-96231b3b80d8
* Add an analyzePhysReg() function to MachineOperandIteratorBase that analyses ↵James Molloy2012-09-121-3/+37
| | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163694 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove 'static' from inline functions defined in header files.Chandler Carruth2012-06-201-2/+2
| | | | | | | | | | | | | | | | | There is a pretty staggering amount of this in LLVM's header files, this is not all of the instances I'm afraid. These include all of the functions that (in my build) are used by a non-static inline (or external) function. Specifically, these issues were caught by the new '-Winternal-linkage-in-inline' warning. I'll try to just clean up the remainder of the clearly redundant "static inline" cases on functions (not methods!) defined within headers if I can do so in a reliable way. There were even several cases of a missing 'inline' altogether, or my personal favorite "static bool inline". Go figure. ;] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158800 91177308-0d34-0410-b5e6-96231b3b80d8
* Move getBundleStart() into MachineInstrBundle.h.Jakob Stoklund Olesen2012-03-011-1/+17
| | | | | | | | | This allows the function to be inlined, and makes it suitable for use in getInstructionIndex(). Also provide a const version. C++ is great for touch typing practice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151782 91177308-0d34-0410-b5e6-96231b3b80d8
* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151690 91177308-0d34-0410-b5e6-96231b3b80d8
* Move the operand iterator into MachineInstrBundle.h where it belongs.Jakob Stoklund Olesen2012-02-291-0/+108
| | | | | | | | | Extract a base class and provide four specific sub-classes for iterating over const/non-const bundles/instructions. This eliminates the mystery bool constructor argument. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151684 91177308-0d34-0410-b5e6-96231b3b80d8
* More bundle related API additions.Evan Cheng2012-01-191-0/+4

* Enhance finalizeBundle to return end of bundle iterator because it makes sense.Evan Cheng2012-01-191-2/+3

* - Slight change to finalizeBundle() interface. LastMI is not exclusive (pointingEvan Cheng2012-01-191-1/+8
| | | | | | | | | | | | 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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148444 91177308-0d34-0410-b5e6-96231b3b80d8

* - Add MachineInstrBundle.h and MachineInstrBundle.cpp. This includes a functionEvan Cheng2011-12-141-0/+34
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146542 91177308-0d34-0410-b5e6-96231b3b80d8
