2011-07-27ARM assembly parsing and encoding for UMLAL.Jim Grosbach
Fix parsing of the 's' suffix for the mnemonic. Add tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136274 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-27ARM parsing and encoding of SBFX and UBFX.Jim Grosbach
Encode the width operand as it encodes in the instruction, which simplifies the disassembler and the encoder, by using the imm1_32 operand def. Add a diagnostic for the context-sensitive constraint that the width must be in the range [1,32-lsb]. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136264 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-27ARM assembly parsing and encoding for extend instructions.Jim Grosbach
Assembly parser handling for extend instruction rotate operands. Add tests for the sign extend instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136252 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-26Fix over-zealous rename from r136095.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136132 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-26ARM diagnostics for ldrexd/stredx out of order paired register operands.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136110 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-26Clean up the ARM asm parser a bit.Jim Grosbach
No intendeded functional change. Just cleaning up a bit to make things more self-consistent in layout and style. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136095 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-26ARM parsing and encoding for SVC instruction.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136090 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-26Rename TargetAsmParser to MCTargetAsmParser and TargetAsmLexer to ↵Evan Cheng
MCTargetAsmLexer; rename createAsmLexer to createMCAsmLexer and createAsmParser to createMCAsmParser. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136027 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-25ARM assembly parsing and encoding for SSAT16 instruction.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136006 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-25ARM assembly parsing and encoding for SSAT instruction.Jim Grosbach
Fix the Rn register encoding for both SSAT and USAT. Update the parsing of the shift operand to correctly handle the allowed shift types and immediate ranges and issue meaningful diagnostics when an illegal value or shift type is specified. Add aliases to parse an ommitted shift operand (default value of 'lsl #0'). Add tests for diagnostics and proper encoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135990 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-25Fix more MC layering violations.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135979 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-25ARM asm operand renaming. Make things a bit more explicit.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135959 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-25Make assembly parser method names more consistent.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135950 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-23Move TargetAsmParser.h TargetAsmBackend.h and TargetAsmLexer.h to MC where ↵Evan Cheng
they belong. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135833 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-22ARM SSAT instruction 5-bit immediate handling.Jim Grosbach
The immediate is in the range 1-32, but is encoded as 0-31 in a 5-bit bitfield. Update the representation such that we store the operand as 0-31, allowing us to remove the encoder method and the special case handling in the disassembler. Update the assembly parser and the instruction printer accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135823 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-22ARM assembly parsing and encoding updates.Jim Grosbach
Tests for SMULBB, SMLALBT, SMLALTB, SMLALTT, and SMULL. Fix parsing of SMULLS. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135817 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-22ARM assembly parsing and encoding of SMLAL instruction.Jim Grosbach
Fix parsing of carry-setting variant SMLALS and add tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135797 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-22ARM assembly parsing and encoding for SETEND instruction.Jim Grosbach
Add parsing and diagnostics for malformed inputs. Tests for diagnostics and for correct encodings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135776 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-21Get rid of the extraneous GPR operand on so_reg_imm operands, which in turn ↵Owen Anderson
necessitates a lot of changes to related bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135722 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-21ARM Asm parser range checking for [0,31] immediates.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135719 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-21Tidy up.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135706 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-21Split up the ARM so_reg ComplexPattern into so_reg_reg and so_reg_imm, ↵Owen Anderson
allowing us to distinguish the encodings that use shifted registers from those that use shifted immediates. This is necessary to allow the fixed-length decoder to distinguish things like BICS vs LDRH. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135693 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-21ARM assembly parsing and encoding for PKHBT and PKHTB instructions.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135682 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-20Sink ARMMCExpr and ARMAddressingModes into MC layer. First step to separate ↵Evan Cheng
ARM MC code from target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135636 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-20ARM assembly parsing of MUL instruction.Jim Grosbach
Correctly handle 's' bit and predication suffices. Add parsing and encoding tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135596 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-19Tweak ARM assembly parsing and printing of MSR instruction.Jim Grosbach
The system register spec should be case insensitive. The preferred form for output with mask values of 4, 8, and 12 references APSR rather than CPSR. Update and tidy up tests accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135532 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-19ARM assembly parsing for MOV (register).Jim Grosbach
Correct the handling of the 's' suffix when parsing ARM mode. It's only a truly separate opcode in Thumb. Add test cases to make sure we handle the s and condition suffices correctly, including diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135513 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-19Tidy up.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135507 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-19Tighten conditional for 'mov' cc_out.Jim Grosbach
Make sure we only clobber the cc_out operand if it is indeed a default non-setting operand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135506 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-19ARM assembly parsing for MOV (immediate).Jim Grosbach
Add range checking for the immediate operand and handle the "mov" mnemonic choosing between encodings based on the value of the immediate. Add tests for fixups, encoding choice and values, and diagnostic for out of range values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135500 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-19Remove unused code.Jim Grosbach
cc_out and pred operands are added during parsing via custom C++ now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135497 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-19ARM range checking for so_imm operands in assembly parsing.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135489 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14ARM diagnostic when 's' suffix on mnemonic that can't set flags.Jim Grosbach
For example, "mlss r0, r1, r2, r3". The MLS instruction does not have a flag-setting variant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135203 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14Next round of MC refactoring. This patch factor MC table instantiations, MCEvan Cheng
registeration and creation code into XXXMCDesc libraries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135184 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14Don't leak operands when putting them into a shift.Benjamin Kramer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135169 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-13ARM Assembler support for DMB instruction.Jim Grosbach
Flesh out the options supported for the instruction. Shuffle tests a bit and add entries for the rest of the options. Add an alias to handle the default operand of "sy". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135109 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-13Range checking for CDP[2] immediates.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135092 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-13Range checking for 16-bit immediates in ARM assembly.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135071 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-13Improve ARM assembly parsing diagnostics a bit.Jim Grosbach
Catch potential cascading errors on a malformed so_reg operand and bail after the first error. Add some tests for the diagnostics we do want. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135055 91177308-0d34-0410-b5e6-96231b3b80d8
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
2011-07-08Fix indentation.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134764 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-08Add support for ARM / Thumb mode switching with .code 16 and .code 32.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134760 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-08Plug a leak by giving the AsmParser ownership of the MCSubtargetInfo.Benjamin Kramer
Found by valgrind. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134738 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
