Bill Wendling 193961bb1a Some instructions end with an "ls" prefix, but it doesn't indicate that they are 
conditional. Check for those instructions explicitly.

Jim Grosbach 305ec65927 Revert 117660. Apparently it's not as trivial as that...

Eric Christopher 91d7b90185 Add an unreachable to silence warning - the switch is actually 
fully enumerated.

llvm-svn: 117647
 2010-10-29 09:26:59 +00:00
Chris Lattner 5d6f6a061b add simple support for addrmode5 operands, allowing 
vldr.64 to work.  I have no idea if this is fully right, but 
it is in the right direction.

llvm-svn: 117626
 2010-10-29 00:27:31 +00:00
Chris Lattner d27b05e54a give better error diagnostics, for example: 
t.s:1:14: error: invalid operand for instruction
vldr.64	d17, [r0]   
       	     ^

instead of:

t.s:1:1: error: unrecognized instruction
vldr.64	d17, [r0]   
^

Chandler Carruth 1898262a33 Remove remaining uses of ATTRIBUTE_UNUSED on variables, and delete three 
#includes in the process.

Chris Lattner a63292a3ca implement rdar://8456378 and PR7557 - support for the fstsw, 
an instruction that requires a WHOLE NEW wonderful kind of alias.

llvm-svn: 115015
 2010-09-29 01:50:45 +00:00
Chris Lattner b44fd24fc1 change the protocol TargetAsmPArser::MatchInstruction method to take an 
MCStreamer to emit into instead of an MCInst to fill in.  This allows the
matcher extra flexibility and is more convenient.

llvm-svn: 115014
 2010-09-29 01:42:58 +00:00
Chris Lattner a2a9d16b78 fix the asmparser so that the target is responsible for skipping to 
the end of the line on a parser error, allowing skipping to happen
for syntactic errors but not for semantic errors.  Before we would
miss emitting a diagnostic about the second line, because we skipped
it due to the semantic error on the first line:

  foo %eax
  bar %al

This fixes rdar://8414033 - llvm-mc ignores lines after an invalid instruction mnemonic errors

llvm-svn: 113688
 2010-09-11 16:18:25 +00:00
Chris Lattner 91689c1d0f change the MC "ParseInstruction" interface to make it the 
implementation's job to check for and lex the EndOfStatement
marker.

llvm-svn: 113347
 2010-09-08 05:10:46 +00:00
Chris Lattner 339cc7bfef in the case where an instruction only has one implementation 
of a mneumonic, report operand errors with better location
info.  For example, we now report:

t.s:6:14: error: invalid operand for instruction
        cwtl $1
             ^

but we fail for common cases like:

t.s:11:4: error: invalid operand for instruction
   addl $1, $1
   ^

because we don't know if this is supposed to be the reg/imm or imm/reg
form.

Chris Lattner a22a368e7c change MatchInstructionImpl to return an enum instead of bool.

 2010-09-06 19:22:17 +00:00
Chris Lattner 3e4582ada5 have AsmMatcherEmitter.cpp produce the hunk of code that gets included 
into the middle of the class, and rework how the different sections of
the generated file are conditionally included for simplicity.

Daniel Dunbar 2ecc3bb4f7 MC/AsmParser: Push the burdon of emitting diagnostics about unmatched 
instructions onto the target specific parser, which can do a better job.

llvm-svn: 110889
 2010-08-12 00:55:38 +00:00
Daniel Dunbar 167b9d7f30 tblgen/AsmMatcher: Always emit the match function as 'MatchInstructionImpl', 
target specific parsers can adapt the TargetAsmParser to this.

llvm-svn: 110888
 2010-08-12 00:55:32 +00:00
Daniel Dunbar 188b47b214 MC/ARM: Add basic support for handling predication by parsing it out of the mnemonic into a separate operand form.

llvm-svn: 110792
 2010-08-11 06:37:12 +00:00
Daniel Dunbar ebace2248f MCAsmParser: Add dump() hook to MCParsedAsmOperand. 
llvm-svn: 110790
 2010-08-11 06:37:04 +00:00
Daniel Dunbar d8042b7bd7 MC/ARM: Add an ARMOperand class for condition codes. 
llvm-svn: 110788
 2010-08-11 06:36:53 +00:00
Daniel Dunbar 5cd4d0f9ac MC/ARM: Switch to using the generated match functions instead of stub implementations. 
llvm-svn: 110783
 2010-08-11 05:24:50 +00:00
Daniel Dunbar 419197cc4d Target: Give the TargetAsmParser access to the TargetMachine. 
- Unfortunate, but necessary for now to handle subtarget instruction matching. Eventually we should factor out the lower level target machine information so we don't need to do this.

and thumb_mode.

Sean Callanan 643a55708f Added an AsmLexer for the ARM target, which uses 
a simple mapping of register names to IDs to
identify register tokens.

llvm-svn: 100685
 2010-04-07 20:29:34 +00:00
Sean Callanan 7ad0ad0b9a Added support for reporting operand token ranges 
to the ARM AsmParser.

llvm-svn: 100232
 2010-04-02 22:27:05 +00:00
Chris Lattner 00646cfbd4 create a new MCParser library and move some stuff into it. 
llvm-svn: 94129
 2010-01-22 01:44:57 +00:00
Sean Callanan 936b0d3144 Promoted the getTok() method to MCAsmParser so that 
the two token accessor functions are declared consistently.
Modified the clients of MCAsmParser to reflect this change.

llvm-svn: 93916
 2010-01-19 21:44:56 +00:00
Sean Callanan a83fd7d52c Propagated the parser-side Lex function's declaration to 
MCAsmParser, and changed the target-specific AsmParsers
to use it.

Chris Lattner c35681b298 Generalize mcasmstreamer data emission APIs to take an address space 
identifier.  There is no way to work around it.

Chris Lattner f29c0b6880 Split the TargetAsmParser "ParseInstruction" interface in half: 
the new ParseInstruction method just parses and returns a list of
target operands.  A new MatchInstruction interface is used to
turn the operand list into an MCInst.

This requires new/deleting all the operands, but it also gives 
targets the ability to use polymorphic operands if they want to. 

llvm-svn: 93469
 2010-01-14 22:21:20 +00:00
Chris Lattner 77fd677111 prune #includes in TargetAsmParser.h 
Pass in SMLoc of instr opcode into ParseInstruction.
Make AsmToken be a class, not a struct.

Bill Wendling b8d960d615 Add an "ATTRIBUTE_UNUSED" macro (and use it). It's for variables which are 
mainly used in debugging and/or assert situations. It should make the compiler
and the static analyzer stop nagging us about them.
