2012-11-20	Fix physical register liveness calculations:	Tim Northover	1	-2/+4
	+ Take account of clobbers + Give outputs priority over inputs since they happen later. llvm-svn: 168360
2012-09-17	Increase the static sizes of some SmallSets. finalizeBundle() is very ↵	Michael Ilseman	1	-4/+4
	frequently called for some backends, and growing into an std::set is overkill for these numbers. llvm-svn: 164044
2012-09-17	whitespace	Michael Ilseman	1	-1/+1
	llvm-svn: 164043
2012-09-12	Add an analyzePhysReg() function to MachineOperandIteratorBase that analyses ↵	James Molloy	1	-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
2012-06-01	Switch all register list clients to the new MC*Iterator interface.	Jakob Stoklund Olesen	1	-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
2012-03-06	Avoid finalizeBundles infinite looping.	Evan Cheng	1	-0/+2
	llvm-svn: 152089
2012-03-05	Convert more GenRegisterInfo tables from unsigned to uint16_t to reduce ↵	Craig Topper	1	-1/+1
	static data size. llvm-svn: 152016
2012-02-29	Add an analyzeVirtReg() function.	Jakob Stoklund Olesen	1	-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
2012-02-08	Codegen pass definition cleanup. No functionality.	Andrew Trick	1	-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
2012-01-19	More bundle related API additions.	Evan Cheng	1	-1/+52
	llvm-svn: 148465
2012-01-19	Enhance finalizeBundle to return end of bundle iterator because it makes sense.	Evan Cheng	1	-3/+6
	llvm-svn: 148462
2012-01-19	- Slight change to finalizeBundle() interface. LastMI is not exclusive (pointing	Evan Cheng	1	-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
2012-01-19	Rename Finalizebundle to finalizeBundle to conform to coding guideline.	Evan Cheng	1	-2/+2
	llvm-svn: 148440
2011-12-14	- Add MachineInstrBundle.h and MachineInstrBundle.cpp. This includes a function	Evan Cheng	1	-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
