2011-06-28- Rename TargetInstrDesc, TargetOperandInfo to MCInstrDesc and MCOperandInfo andEvan Cheng
sink them into MC layer. - Added MCInstrInfo, which captures the tablegen generated static data. Chang TargetInstrInfo so it's based off MCInstrInfo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134021 91177308-0d34-0410-b5e6-96231b3b80d8

into XXXGenRegisterInfo.inc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133922 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-24Starting to refactor Target to separate out code that's needed to fully describeEvan Cheng
target machine from those that are only needed by codegen. The goal is to sink the essential target description into MC layer so we can start building MC based tools without needing to link in the entire codegen. First step is to refactor TargetRegisterInfo. This patch added a base class MCRegisterInfo which TargetRegisterInfo is derived from. Changed TableGen to separate register description from the rest of the stuff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133782 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-15Use set operations instead of plain lists to enumerate register classes.Jakob Stoklund Olesen
This simplifies many of the target description files since it is common for register classes to be related or contain sequences of numbered registers. I have verified that this doesn't change the files generated by TableGen for ARM and X86. It alters the allocation order of MBlaze GPR and Mips FGR32 registers, but I believe the change is benign. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133105 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-09Remove custom allocation order boilerplate that is no longer needed.Jakob Stoklund Olesen
The register allocators automatically filter out reserved registers and place the callee saved registers last in the allocation order, so custom methods are no longer necessary just for that. Some targets still use custom allocation orders: ARM/Thumb: The high registers are removed from GPR in thumb mode. The NEON allocation orders prefer to use non-VFP2 registers first. X86: The GR8 classes omit AH-DH in x86-64 mode to avoid REX trouble. SystemZ: Some of the allocation orders are omitting R12 aliases without explanation. I don't understand this target well enough to fix that. It looks like all the boilerplate could be removed by reserving the right registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132781 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-21Revert r124611 - "Keep track of incoming argument's location while emitting ↵Devang Patel
LiveIns." In other words, do not keep track of argument's location. The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body. This requires some coordination with debugger to get this working. - The debugger needs to be aware of prolog_end attribute attached with line table entries. - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126155 91177308-0d34-0410-b5e6-96231b3b80d8
