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.

 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.

Daniel Dunbar c5ddbad237 MC: Provide MCAssembler with a TargetAsmBackend. 
llvm-svn: 98222
 2010-03-11 01:34:27 +00:00
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.

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.

llvm-svn: 94164
 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. 
llvm-svn: 94129

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.

 2009-12-28 01:34:57 +00:00
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

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 
    ^

llvm-svn: 91896
 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
 2009-12-22 06:37:58 +00:00
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.

llvm-svn: 91579
 2009-12-17 01:49:59 +00:00
Nick Lewycky e0856c5f40 Line this up as well. 
llvm-svn: 85748

 2009-11-01 22:07:54 +00:00
Chandler Carruth 56869f22c4 Move DataTypes.h to include/llvm/System, update all users. This breaks the last 
direct inclusion edge from System to Support.

Daniel Dunbar 5f339244fb MC: Tweak variable assignment diagnostics, and make reassignment of non-absolute 
variables and symbols invalid.

llvm-svn: 84232
 2009-10-16 01:57:39 +00:00
Daniel Dunbar d20cda028a MC: When parsing a variable reference, substitute absolute variables immediately 
since they are allowed to be redefined.

llvm-svn: 84230
 2009-10-16 01:34:54 +00:00
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.

llvm-svn: 82926

Chris Lattner 10a1cfd0f9 avoid copying MCAsmInfo by value, add an (extremely low prio) fixme. 
llvm-svn: 82911
 2009-09-27 19:38:39 +00:00
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"

llvm-svn: 82385
 2009-09-20 07:17:49 +00:00
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().

llvm-svn: 82059
 2009-09-16 18:08:00 +00:00
Chris Lattner c6a889d0b6 use an accessor to simplify code. 
llvm-svn: 81997
 2009-09-16 04:12:47 +00:00
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.

llvm-svn: 81754
 2009-09-14 03:02:37 +00:00
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.

llvm-svn: 81461
 2009-09-10 20:51:44 +00:00
Daniel Dunbar a944234a1e MC: Give target specific parsers access to the MCStreamer. 
llvm-svn: 81416

Benjamin Kramer 63951ada31 Fix an integer truncation noticed by MSVC. 
llvm-svn: 81109
 2009-09-06 09:35:10 +00:00
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
 2009-09-04 22:40:31 +00:00
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.

llvm-svn: 81046
 2009-09-04 21:45:34 +00:00
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.

Chris Lattner 41bf56de79 TAI -> MAI 
llvm-svn: 80899
 2009-09-03 06:13:54 +00:00
Daniel Dunbar 897ffadd2d llvm-mc: Pass values to MCStreamer as MCExprs, not MCValues. 
llvm-svn: 80578
 2009-08-31 08:09:28 +00:00
Daniel Dunbar b7b2097aac llvm-mc: Simplify EmitAssignment ('.set' is identical to '='). 
llvm-svn: 80577
 2009-08-31 08:09:09 +00:00
Daniel Dunbar b12b33051d llvm-mc: Remove MCAsmParser::Parse[Paren]RelocatableExpression. 
llvm-svn: 80576
 2009-08-31 08:08:50 +00:00
Daniel Dunbar 7c82d56930 llvm-mc: Add MCAsmParser::Parse[Paren]Expression forms which return an MCExpr. 
llvm-svn: 80574
 2009-08-31 08:08:17 +00:00
Daniel Dunbar 940cda2590 llvm-mc: Add MCAsmParser::getContext. 
llvm-svn: 80571
 2009-08-31 08:07:44 +00:00
Daniel Dunbar f363645da2 llvm-mc: Switch MCExpr construction to using static member functions, and taking the MCContext (which now owns all MCExprs). 
llvm-svn: 80569
 2009-08-31 08:07:22 +00:00
Daniel Dunbar 115e4d6d7b llvm-mc: Move AsmExpr into MC lib (as MCExpr). 
llvm-svn: 80567
 2009-08-31 08:06:59 +00:00
Daniel Dunbar 6a715dccdf llvm-mc: MCStreamer cleanups. - Remove EmitLocalSymbol, this is unsupported for now. 
- Switch Emit{CommonSymbol,Zerofill} to take alignment in bytes (for consistency).

llvm-svn: 80484
 2009-08-30 06:17:16 +00:00
Daniel Dunbar 96abad185d llvm-mc: Emit .lcomm as .zerofill.

Daniel Dunbar ba33ff294e llvm-mc: Unique sections in .zerofill. 
llvm-svn: 80305
 2009-08-27 23:45:06 +00:00
Daniel Dunbar c7c5f9fa86 llvm-mc/Mach-O: Add MCCodeEmitter support, for encoding instructions. 
- No relocations yet, of course.

llvm-svn: 80235
 2009-08-27 08:17:51 +00:00
Daniel Dunbar d18dd1d5f8 llvm-mc: Only show instruction encodings with --show-encoding. 
llvm-svn: 80230
 2009-08-27 07:56:39 +00:00
Daniel Dunbar 81cb753298 llvm-mc: Tweak MCCodeEmitter skeleton. 
llvm-svn: 80193
 2009-08-27 01:34:22 +00:00
Daniel Dunbar 65105174a6 Sketch TargetRegistry support for MCCodeEmitter abstract interface. 
- Of course, nothing actually can provide this interface yet.

llvm-svn: 80188
 2009-08-27 00:51:57 +00:00
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.

llvm-svn: 80168
 2009-08-26 22:49:51 +00:00
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).

llvm-svn: 80162
 2009-08-26 22:13:22 +00:00
Daniel Dunbar 90398bd222 llvm-mc: Make MCValue take const MCSymbol*s. 
llvm-svn: 80078
 2009-08-26 09:16:46 +00:00
Daniel Dunbar 18f3c9b994 llvm-mc: Make non-sensical max bytes to .align an error. 
Also, warn about overflow in alignment values.

llvm-svn: 80077
 2009-08-26 09:16:34 +00:00
Dan Gohman 61a8796ddb Make LLVM command-line tools overwrite their output files without -f. 
This is conventional command-line tool behavior. -f now just means
"enable binary output on terminals".

Add a -f option to llvm-extract and llvm-link, for consistency.

Remove F_Force from raw_fd_ostream and enable overwriting and
truncating by default. Introduce an F_Excl flag to permit users to
enable a failure when the file already exists. This flag is
currently unused.

Update Makefiles and documentation accordingly.

llvm-svn: 79990
 2009-08-25 15:34:52 +00:00
Chris Lattner 9e6f1f160a Change raw_fd_ostream to take flags as an optional bitmask 
instead of as two bools.  Use this to add a F_Append flag
which has the obvious behavior.

Other unrelated changes conflated into this patch:

1. REmove EH stuff from llvm-dis and llvm-as, the try blocks
   are dead.
2. Simplify the filename inference code in llvm-as/llvm-dis,
   because raw_fd_ostream does the right thing with '-'.
3. Switch machine verifier to use raw_ostream instead of ostream
   (Which is the thing that needed append in the first place).

llvm-svn: 79807
 2009-08-23 02:51:22 +00:00
Chris Lattner 7b26fce23e Rename TargetAsmInfo (and its subclasses) to MCAsmInfo. 
llvm-svn: 79763
 2009-08-22 20:48:53 +00:00
Daniel Dunbar 6860ac7375 llvm-mc: Clean up some handling of symbol/section association to be more correct 
(external was really undefined and there wasn't an explicit representation for
absolute symbols).
 - This still needs some cleanup to how the absolute "pseudo" section is dealt
   with, but I haven't figured out the nicest approach yet.

llvm-svn: 79733
 2009-08-22 07:22:36 +00:00
Daniel Dunbar 67dfb1de23 llvm-mc: Improve handling of implicit alignment for magic section directives 
(e.g., .objc_message_refs).
 - Just emit a .align when we see the directive; this isn't exactly what 'as'
   does but in practice it should be ok, at least for now. See FIXME.

llvm-svn: 79697
 2009-08-21 23:30:15 +00:00
Daniel Dunbar 4abcccb965 llvm-mc: In a .fill directive, still honor .align even if invalid maximum bytes 
count is given (this matches 'as').

llvm-svn: 79683
 2009-08-21 23:01:53 +00:00
Daniel Dunbar 8e5edd81bb llvm-mc: Accept .fill size of 8. 
llvm-svn: 79635
 2009-08-21 15:43:35 +00:00
Daniel Dunbar 3016db39dd llvm-mc: Start MCAssembler and MCMachOStreamer. 
- Together these form the (Mach-O) back end of the assembler.

 - MCAssembler is the actual assembler backend, which is designed to have a
   reasonable API. This will eventually grow to support multiple object file
   implementations, but for now its Mach-O/i386 only.

 - MCMachOStreamer adapts the MCStreamer "actions" API to the MCAssembler API,
   e.g. converting the various directives into fragments, managing state like
   the current section, and so on.

 - llvm-mc will use the new backend via '-filetype=obj', which may eventually
   be, but is not yet, since I hear that people like assemblers which actually
   assemble.

 - The only thing that works at the moment is changing sections. For the time
   being I have a Python Mach-O dumping tool in test/scripts so this stuff can
   be easily tested, eventually I expect to replace this with a real LLVM tool.

 - More doxyments to come.

I assume that since this stuff doesn't touch any of the things which are part of
2.6 that it is ok to put this in not so long before the freeze, but if someone

Daniel Dunbar 9df5f33818 llvm-mc: Various section parsing fixes. 
- Add missing flags for various Objective-C sections.

 - Fix names for [non_]lazy_symbol_pointer (these are misspelled in the manual).

 - .symbol_stub does not have the self modifying code flag set (this appears to
   be wrong in the manual?).

 - Add implicit alignment values; not yet used.

Also, call MCStreamer::Finish at the end of a successful parse.

 2009-08-14 18:19:52 +00:00
Daniel Dunbar 80d484e7cc Update llvm-mc / MCAsmStreamer to print the instruction using the actual target 
specific printer (this only works on x86, for now).
 - This makes it possible to do some correctness checking of the parsing and
   matching, since we can compare the results of 'as' on the original input, to
   those of 'as' on the output from llvm-mc.

 - In theory, we could now have an easy ATT -> Intel syntax converter. :)

Daniel Dunbar 9af747b421 llvm-mc: Fix darwin .section parsing. It was skipping the section name and a ','

Chris Lattner 97189e5d04 add a fixme 
llvm-svn: 78575
 2009-08-10 18:05:55 +00:00
Chris Lattner cb307a27bf Make the big switch: Change MCSectionMachO to represent a section *semantically* 
instead of syntactically as a string.  This means that it keeps track of the 
segment, section, flags, etc directly and asmprints them in the right format.
This also includes parsing and validation support for llvm-mc and 
"attribute(section)", so we should now start getting errors about invalid 
section attributes from the compiler instead of the assembler on darwin.

Still todo: 
1) Uniquing of darwin mcsections
2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h]
3) there are a few FIXMEs, for example what is the syntax to get the
   S_GB_ZEROFILL segment type?

Kevin Enderby d9f952948e Added Mac OS X assembler style conditional assembly. I may come back and see if 
I can clean this up a bit more and do way with the TheCondState and just use
the top element on the TheCondStack if not empty.  Also may tweak the code
around ParseConditionalAssemblyDirectives() to simplify the AsmParser code.

Daniel Dunbar 47d679151b Add TargetRegistry::lookupTarget. 
- This is a simplified mechanism which just looks up a target based on the
   target triple, with a few additional flags.

 - Remove getClosestStaticTargetForModule, the moral equivalent is now:
     lookupTarget(Mod->getTargetTriple, true, false, ...);

 - This no longer does the fuzzy matching with target data (based on endianness
   and pointer width) that getClosestStaticTargetForModule was doing, but this
   was deemed unnecessary.

   the old style.

 - NIFC.

Kevin Enderby ee5513582d Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API as 
the parsing of the .dump and .load should be done in the assembly parser and

just produce an error saying these specific directives are not yet implemented
since they are likely no longer used and may never need to be implemented.
