Chris Lattner 9f59b3dd9b remove some extraneous casts 
llvm-svn: 100287
 2010-04-03 21:03:50 +00:00
Daniel Dunbar d821f4ac60 llvm-mc: Add a -mc-relax-all option, which relaxes every fixup. We always need 
exactly two passes in that case, and don't ever need to recompute any layout,
so this is a nice baseline for relaxation performance.

llvm-svn: 99563
 2010-03-25 22:49:09 +00:00
Daniel Dunbar b09b8906cb llvm-mc: Support -filetype=null, for timing purposes. 
llvm-svn: 99349
 2010-03-23 23:47:12 +00:00
Daniel Dunbar d9d5b315ab llvm-mc: Fix MCInstPrinter memory leaks. 
llvm-svn: 99101
 2010-03-20 22:36:35 +00:00
Daniel Dunbar c5621ed07a llvm-mc: Fix memory leak of MCAsmInfo. 
llvm-svn: 99098
 2010-03-20 22:36:25 +00:00
Daniel Dunbar abf6e3657e llvm-mc: Fix target selection for --disassemble to use GetTarget. 
llvm-svn: 98973
 2010-03-19 18:07:50 +00:00
Chris Lattner 90a7859ebc fix an MCInstPrinter leak that jyasskin pointed out: 
createAsmStreamer now takes ownership of the instprinter.

llvm-svn: 98939
 2010-03-19 05:48:53 +00:00
Daniel Dunbar 144873437c llvm-mc: Delete output files on error. 
llvm-svn: 98445
 2010-03-13 19:31:47 +00:00
Daniel Dunbar 322fec671b llvm-mc: Support -n, useful for comparing -integrated-as output since the 
compiler may not lead with the text section.

llvm-svn: 98418
 2010-03-13 02:20:57 +00:00
Daniel Dunbar 4689211583 llvm-mc: Support -arch as a simplified form of -triple. 
llvm-svn: 98417
 2010-03-13 02:20:38 +00:00
Chris Lattner ac77bf5d1e remove MAI argument from createAsmStreamer since it 
can get it from the context now.

llvm-svn: 98361
 2010-03-12 18:28:53 +00:00
Chris Lattner 768ea2add2 change MCContext to always have an MCAsmInfo.

Chris Lattner 741580a5bd give MCCodeEmitters access to the current MCContext. 
llvm-svn: 96038
 2010-02-12 23:12:47 +00:00
Daniel Dunbar 75c9a4eeae llvm-mc: Remove --show-fixups and always show as part of --show-encoding. 
Also, fix a silly memory leak.

llvm-svn: 95752
 2010-02-10 01:41:14 +00:00
Daniel Dunbar 9a0a46163d llvm-mc: Add --show-fixups option, for displaying the instruction fixup information in the asm comments. 
llvm-svn: 95710
 2010-02-09 23:00:14 +00:00
Daniel Dunbar e3ee332fe0 llvm-mc: Add --show-inst option, for showing the MCInst inline with the assembly 
output.

llvm-svn: 95227
 2010-02-03 18:18:30 +00:00
Sean Callanan 6a6f9cc634 Fixed the disassembler so it accepts multiple 
instructions on a single line.  Also made it a
bit more forgiving when it reports errors.

 2010-02-03 03:46:41 +00:00
Chris Lattner 823aed16f9 make -fno-rtti the default unless a directory builds with REQUIRES_RTTI. 
llvm-svn: 94378
 2010-01-24 20:43:08 +00:00
Chris Lattner 0522eb2160 pass "-fasm-verbose" into createAsmStreamer. 
llvm-svn: 94165
 2010-01-22 07:06:15 +00:00
Chris Lattner 7ba0661f27 Stop building RTTI information for *most* llvm libraries. Notable 
missing ones are libsupport, libsystem and libvmcore.  libvmcore is
currently blocked on bugpoint, which uses EH.  Once it stops using
EH, we can switch it off.

This #if 0's out 3 unit tests, because gtest requires RTTI information.
Suggestions welcome on how to fix this.

 2010-01-22 06:49:46 +00:00
Chris Lattner 5b0e01c54e move some files out of the llvm-mc tool into the MCParser library so 
other tools can link it.

llvm-svn: 94131
 2010-01-22 01:58:08 +00:00
Chris Lattner 00646cfbd4 create a new MCParser library and move some stuff into it.

 2010-01-22 01:44:57 +00:00
Chris Lattner 6401c883c4 remove some confused code that used strtoull 
llvm-svn: 94128

Sean Callanan 7a77eae2f3 Moved handling of inclusion from the AsmLexer to 
the AsmParser, breaking AsmLexer's dependence on
SourceMgr.

llvm-svn: 94054
 2010-01-21 00:19:58 +00:00
Sean Callanan 177934e021 Changed the AsmParser to handle error messages itself 
rather than passing them off to the AsmLexer to handle.
This means the AsmLexer no longer requires a SourceMgr
to do error handling.

llvm-svn: 94047
 2010-01-20 23:19:55 +00:00
Sean Callanan 1a0eeb6e06 Promoted the reference to the SourceMgr from AsmLexer 
into AsmParser, in preparation for making AsmLexer
independent of the SourceMgr

llvm-svn: 94043
 2010-01-20 22:45:23 +00:00
Sean Callanan 70855e42e6 Modified MCAsmLexer to return error information upward 
rather than printing it locally, reducing its dependence
on SourceMgr.

llvm-svn: 94041
 2010-01-20 22:18:24 +00:00
Chris Lattner 38caaf14c1 give createAsmStreamer an 'isLittleEndian' argument. 
llvm-svn: 93986
 2010-01-20 06:39:07 +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 686ed8d248 Added a Lex function to the AsmParser, to allow handling 
of include directives to occur within the parser itself.
This will break the lexer's dependency on a SourceMgr as
input.

llvm-svn: 93899
 2010-01-19 20:22:31 +00:00
Chris Lattner c35681b298 Generalize mcasmstreamer data emission APIs to take an address space 
identifier.  There is no way to work around it.

llvm-svn: 93896
 2010-01-19 19:46:13 +00:00
Chris Lattner 0c65fd4902 add a "MCStreamer::EmitFill" method, and move the default implementation 
(which just iteratively emits bytes) to MCStreamer.

llvm-svn: 93888
 2010-01-19 18:45:47 +00:00
Chris Lattner ab9cd3e132 fix parsing .comm directives on systems which do not represent alignments 
as a power of 2.  This fixes MC/AsmParser/directive_comm.s

llvm-svn: 93867
 2010-01-19 06:22:22 +00:00
Chris Lattner e17df0b7f0 fix a bug in range information for $42, eliminate an 
unneeded argument from ParseExpression.

llvm-svn: 93536
 2010-01-15 19:39:23 +00:00
Chris Lattner 528d00b913 extend MCAsmParser::ParseExpression and ParseParenExpression 
to return range information for subexpressions.  Use this to
provide range info for several new X86Operands.

llvm-svn: 93534
 2010-01-15 19:28:38 +00:00
Chris Lattner 14bf521792 add virtual methods to get the start/end of a MCParsedAsmOperand, 
the default implementation returns "unknown".

llvm-svn: 93470
 2010-01-14 22:29:57 +00:00
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.

llvm-svn: 93457
 2010-01-14 21:32:45 +00:00
Bill Wendling ae606a1d1d Mark some debug variables as 'unused' to quiet compiler and analyzer.

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

llvm-svn: 91934
 2009-12-22 22:50:29 +00:00
Chris Lattner e3437b33f5 just discard the debug output from the disassembler. 
llvm-svn: 91933

Chris Lattner 778f92ab02 specify what is invalid about it 
llvm-svn: 91901
 2009-12-22 07:03:21 +00:00
Chris Lattner 502f0f11e0 reject invalid input with a caret, e.g.: 
simple-tests.txt:16:1: error: invalid instruction
0xff 0xff
^

llvm-svn: 91898
 2009-12-22 06:58:29 +00:00
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 
    ^

 2009-12-22 06:56:51 +00:00
Chris Lattner 8879918722 If you thought that it didn't make sense for the disassembler 
to not produce caret diagnostics, you were right!

llvm-svn: 91895
 2009-12-22 06:45:48 +00:00
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

llvm-svn: 91894

Chris Lattner 72cbaa2ecb don't crash on blank lines, rename some variables.

Chandler Carruth 187220e3f5 Update CMake build to include HexDisassembler.cpp. 
llvm-svn: 91589
 2009-12-17 06:35:17 +00:00
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.
