2011-07-13Flesh out ARM Parser support for shifted-register operands.Jim Grosbach
Now works for parsing register shifted register and register shifted immediate arithmetic instructions, including the 'rrx' rotate with extend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135049 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-13Update MCParsedAsmOperand debug methods.Jim Grosbach
Update the debug output interface for MCParsedAsmOperand to have a print() method which takes an output stream argument, an << operator which invokes the print method using the given stream, and a dump() method which prints the operand to the dbgs() stream. This makes the interface more consistent with the rest of LLVM, and more convenient to use at the debugger command line. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135043 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-11Fix recognition of ARM 'adcs' mnemonic.Jim Grosbach
The 'CS' is not a predication suffix in this case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134903 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-09Change createAsmParser to take a MCSubtargetInfo instead of triple,Evan Cheng
CPU, and feature string. Parsing some asm directives can change subtarget state (e.g. .code 16) and it must be reflected in other modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance must be shared. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134795 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-08TargetAsmParser doesn't need reference to Target.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134721 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-08Eliminate asm parser's dependency on TargetMachine:Evan Cheng
- Each target asm parser now creates its own MCSubtatgetInfo (if needed). - Changed AssemblerPredicate to take subtarget features which tablegen uses to generate asm matcher subtarget feature queries. e.g. "ModeThumb,FeatureThumb2" is translated to "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134678 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-30Thumb1 register to register MOV instruction is predicable.Jim Grosbach
Fix a FIXME and allow predication (in Thumb2) for the T1 register to register MOV instructions. This allows some better codegen with if-conversion (as seen in the test updates), plus it lays the groundwork for pseudo-izing the tMOVCC instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134197 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-30Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name toEvan Cheng
be the first encoded as the first feature. It then uses the CPU name to look up features / scheduling itineray even though clients know full well the CPU name being used to query these properties. The fix is to just have the clients explictly pass the CPU name! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134127 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-27ARM Assembly support for Thumb mov-immediate.Jim Grosbach
Correctly parse the forms of the Thumb mov-immediate instruction: 1. 8-bit immediate 0-255. 2. 12-bit shifted-immediate. The 16-bit immediate "movw" form is also legal with just a "mov" mnemonic, but is not yet supported. More parser logic necessary there due to fixups. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133966 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-27ARM Asm parsing of Thumb2 move immediate.Jim Grosbach
Thumb2 MOV mnemonic can accept both cc_out and predication. We don't (yet) encode the instruction properly, but this gets the parsing part. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133945 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-30- Implement asm parsing support for LDRT, LDRBT, STRT, STRBT andBruno Cardoso Lopes
{STR,LDC}{2}_PRE. - Fixed the encoding in some places. - Some of those instructions were using am2offset and now use addrmode2. Codegen isn't affected, instructions which use SelectAddrMode2Offset were not touched. - Teach printAddrMode2Operand to check by the addressing mode which index mode to print. - This is a work in progress, more work to come. The idea is to change places which use am2offset to use addrmode2 instead, as to unify assembly parser. - Add testcases for assembly parser git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128585 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-14Fix encoding and add parsing support for the arm/thumb CPS instruction:Bruno Cardoso Lopes
- Add custom operand matching for imod and iflags. - Rename SplitMnemonicAndCC to SplitMnemonic since it splits more than CC from mnemonic. - While adding ".w" as an operand, don't change "Head" to avoid passing the wrong mnemonic to ParseOperand. - Add asm parser tests. - Add disassembler tests just to make sure it can catch all cps versions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125489 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-12AsmMatcher custom operand parser failure enhancements.Jim Grosbach
Teach the AsmMatcher handling to distinguish between an error custom-parsing an operand and a failure to match. The former should propogate the error upwards, while the latter should continue attempting to parse with alternative matchers. Update the ARM asm parser accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125426 91177308-0d34-0410-b5e6-96231b3b80d8
