Chris Lattner b257d24f62 rename HexDisassembler -> Disassembler, it works on any input
integer encoding (0123, 0b10101, 42, etc).

Chris Lattner e3437b33f5 just discard the debug output from the disassembler.

Chris Lattner 502f0f11e0 reject invalid input with a caret, e.g.:
simple-tests.txt:16:1: error: invalid instruction
0xff 0xff

Chris Lattner dd0c01b5de various cleanups, make the disassemble reject lines with too much
data on them, for example:

	addb	%al, (%rax)
simple-tests.txt:11:5: error: excess data detected in input
0 0 0 0 0 
    ^

Chris Lattner 8879918722 If you thought that it didn't make sense for the disassembler
to not produce caret diagnostics, you were right!

Chris Lattner dc9845b79a rewrite the file parser for the disassembler, implementing support for
comments.  Also, check in a simple testcase for the disassembler,
including a test for r91864

Sean Callanan 7e64550747 Test harness for the LLVM disassembler. When invoked
with -disassemble, llvm-mc now accepts lines of the
form
0x00 0x00
and passes the resulting bytes to the disassembler for
the chosen (or default) target, printing the result.

variables and symbols invalid.

Daniel Dunbar d20cda028a MC: When parsing a variable reference, substitute absolute variables immediately
since they are allowed to be redefined.

Chris Lattner 351a7ef01a add a new DirectiveMap stringmap, which allows more efficient dispatching
to directive handlers and allows for easier extensibility.

I only switched a few over for now.

Chris Lattner 4479034537 Add an intel syntax MCInstPrinter implementation. You can now
transcode from AT&T to intel syntax with "llvm-mc foo.s -output-asm-variant=1"

Kevin Enderby ecd879a2d5 Fixed some problems with the logic of parsing line comments by adding
isAtStartOfComment and using that instead in two places where a loop
to check if the char was in MAI.getCommentString().

Chris Lattner 11b2fc9ea4 Change MCAsmStreamer to take an MCInstPrinter instead of a
full AsmPrinter, and change TargetRegistry to keep track
of registered MCInstPrinters.

llvm-mc is still linking in the entire
target foo to get the code emitter stuff, but this is an
important step in the right direction.

Kevin Enderby ce4bec8e0c Added the ParseInstruction() hook for target specific assembler directives so
that things like .word can be parsed as target specific.  Moved parsing .word
out of AsmParser.cpp into X86AsmParser.cpp as it is 2 bytes on X86 and 4 bytes
for other targets that support the .word directive.

Kevin Enderby 9c0f7fc746 Added AsmToken enum constants to MCAsmLexer.h for '[', ']', '{', and '}' in
preparation of supporting other targets. Then changed the lexer to parse these
as tokens.

llvm-svn: 81050

Kevin Enderby f92f9909c4 Added the AsmToken::Hash enum constant to MCAsmLexer.h in preparation of
supporting other targets.  Changed the code to pass MCAsmInfo to the parser
and the lexer.  Then changed the lexer to use CommentString from MCAsmInfo
instead of a literal '#' character.

Kevin Enderby 7d91218c75 Removed the non-target independent AsmToken::Register enum constant
from MCAsmLexer.h in preparation of supporting other targets.  Changed the
X86AsmParser code to reflect this by removing AsmLexer::LexPercent and looking
for AsmToken::Percent when parsing in places that used AsmToken::Register.
Then changed X86ATTAsmParser::ParseRegister to parse out registers as an
AsmToken::Percent followed by an AsmToken::Identifier.

Daniel Dunbar 4d7b2e3307 llvm-mc/Mach-O: Unique sections properly, so we don't get duplicate text
sections, etc.
 - The quick and dirty way, just clone the TargetLoweringObjectFile
   code. Eventually this should be shared... somehow.

Daniel Dunbar e73b267301 llvm-mc/Mach-O: Don't put assembler temporary labels in the symbol table.
- I moved section creation back into AsmParser. I think policy decisions like
   this should be pushed higher, not lower, when possible (in addition the
   assembler has flags which change this behavior, for example).
