2013-01-04Move an assertion so it doesn't dereference end().Jakob Stoklund Olesen
The R600 target has test cases that exercises this code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171538 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-13Use the new MI bundling API in MachineInstrBundle itself.Jakob Stoklund Olesen
The new API is higher level than just manipulating the bundle flags directly, and the setIsInsideBundle() function will disappear soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170159 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
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
2012-11-20Fix physical register liveness calculations:Tim Northover

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
2012-06-01Switch all register list clients to the new MC*Iterator interface.Jakob Stoklund Olesen
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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157854 91177308-0d34-0410-b5e6-96231b3b80d8

static data size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152016 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-29Add an analyzeVirtReg() function.Jakob Stoklund Olesen
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
2012-02-08Codegen pass definition cleanup. No functionality.Andrew Trick
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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150100 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-19Enhance finalizeBundle to return end of bundle iterator because it makes sense.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148462 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-19- Slight change to finalizeBundle() interface. LastMI is not exclusive (pointingEvan Cheng
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

2011-12-14- Add MachineInstrBundle.h and MachineInstrBundle.cpp. This includes a functionEvan Cheng
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
