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 2eca0252c3 llvm-mc: Add -show-inst-operands, for dumping the parsed instruction representation before matching. 
llvm-svn: 110791
 2010-08-11 06:37:09 +00:00
Daniel Dunbar d215976208 MC/AsmParser: Fix a bug in macro argument parsing, which was dropping 
parentheses from argument lists.

llvm-svn: 110692
 2010-08-10 17:38:52 +00:00
Daniel Dunbar b759a13da8 MC: Destroy Macro instances. 
llvm-svn: 109720
 2010-07-29 01:51:55 +00:00
Kevin Enderby e5930f142a Added first bit of support for the dwarf .file directive. This patch collects 
the info from the .file directive and makes file and directory tables that
will eventually be put out as part of the dwarf info in the output file.

llvm-svn: 109651
 2010-07-28 20:55:35 +00:00
Eli Friedman 20b026464e Make .align parse correctly on platforms where .align is measured in bytes.

 2010-07-19 04:17:25 +00:00
Daniel Dunbar 8897d479b5 MC/AsmParser: Stop playing unsafe member function pointer calls, this isn't 
portable enough.
 - Downside is we now double dispatch through a stub function, but this isn't
   performance critical.

llvm-svn: 108661
 2010-07-18 22:22:07 +00:00
Daniel Dunbar 40a564f09f MC/AsmParser: Fix .abort and .secure_log_unique to accept arbitrary token 
sequences, not just strings.

 2010-07-18 18:47:21 +00:00
Daniel Dunbar 828984ff4e MC/AsmParser: Add .macros_{off,on} support, not that makes sense since we don't 
support macros.

llvm-svn: 108649
 2010-07-18 18:38:02 +00:00
Daniel Dunbar d8a1845c31 MC/AsmParser: Use Error() instead of calling PrintMessage() directly. 
llvm-svn: 108648
 2010-07-18 18:31:45 +00:00
Daniel Dunbar 2a2c6cf5f9 MC/AsmParser: Hide the AsmParser implementation.

 2010-07-18 18:31:38 +00:00

Daniel Dunbar c5011088cd MC/AsmParser: Add a DarwinAsmParser extension. 
- Currently initialization is a bit of a hack, but harmless. We need to rework
   various parts of target initialization to clean this up.

llvm-svn: 104467
 2010-05-23 18:36:38 +00:00
Daniel Dunbar 8271d1bb4a llvm-mc: Use AddBlankLine in asm parser. This makes transliteration match the input much more closely, and also makes the API calls from the AsmParser and CodeGen line up better.

Daniel Dunbar bb166bed40 MC/Mach-O/x86: Optimal nop sequences should only be used for the .text sections, not all sections in the text segment. 
llvm-svn: 103981
 2010-05-17 21:54:30 +00:00
Daniel Dunbar 9b4a824217 llvm-mc: Support reassignment of variables in one special case, when the 
variable has not yet been used in an expression. This allows us to support a few
cases that show up in real code (mostly because gcc generates it for Objective-C
on Darwin), without giving up a reasonable semantic model for assignment.

llvm-svn: 103950
 2010-05-17 17:46:23 +00:00
Eric Christopher 68b1bbe66a Assume that we'll handle mangling the symbols earlier and just put the 
symbol to the file as we have it.  Simplifies out tbss handling.

llvm-svn: 103928
 2010-05-17 02:13:02 +00:00
Eric Christopher 9fb6bb07ca Add AsmParser support for darwin tbss directive.

 2010-05-14 01:38:54 +00:00
Chris Lattner 8cb4728a15 fix rdar://7965971 and a fixme: use ParseIdentifier in 
ParseDirectiveDarwinZerofill instead of hard coding the
check for identifier. This allows quoted symbol names to
be used.

Daniel Dunbar deb7ba9cc0 MC: Reject attempts to define a variable symbol.

Daniel Dunbar ce0c1e11ce llvm-mc: Fix case were we would skip a line in the .s file after an instruction 
match failure.

Also, fixes a few memory leak FIXMEs.

llvm-svn: 102986
 2010-05-04 00:33:07 +00:00
Chris Lattner 926885c090 refactor .if handling code a bit. 
llvm-svn: 101659
 2010-04-17 18:14:27 +00:00
Chris Lattner 6b55cb9cd8 implement mc asmparser support for '.', which gets the 
current PC.  rdar://7834775

We now produce an identical .o file compared to the cctools
assembler for something like this:

_f0:
L0:
        jmp L1
        .long . - L0
L1:
        jmp A
        .long . - L1

        .zerofill __DATA,_bss,A,0

 2010-04-14 04:40:28 +00:00
Chris Lattner 2073112fc0 move macho section uniquing from MCParser and TLOF to MCContext where 
the compiler and asmparser now unique to the same sections.  This fixes
rdar://7835021.

llvm-svn: 100807
 2010-04-08 20:30:37 +00:00
Chris Lattner 3b21e4d404 Give AsmParser an option to control whether it finalizes 
the stream.  New demo:

$ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
$ otool -tv t.o
t.o:
(__TEXT,__text) section
_foo:
0000000000000000	subq	$0x08,%rsp
0000000000000004	movl	%edi,(%rsp)
0000000000000007	movl	%edi,%eax
0000000000000009	incl	%eax
000000000000000b	movl	%eax,(%rsp)
000000000000000e	movl	%eax,0x04(%rsp)
0000000000000012	addq	$0x08,%rsp
0000000000000016	ret

llvm-svn: 100492
 2010-04-05 23:15:42 +00:00
Chris Lattner 9897043928 Rip out the 'is temporary' nonsense from the MCContext interface to 
create symbols.  It is extremely error prone and a source of a lot
of the remaining integrated assembler bugs on x86-64.

This fixes rdar://7807601.

llvm-svn: 99902
 2010-03-30 18:10:53 +00:00
Daniel Dunbar 5599256415 MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr. 
- Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue.
 - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol.

llvm-svn: 98592
 2010-03-15 23:51:06 +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 7e3283c055 Remove unneeded includes. 
llvm-svn: 98167
 2010-03-10 17:56:05 +00:00
Chris Lattner b973ea88b5 eliminate MCContext::CreateSymbol and CreateTemporarySymbol. 
Add a new GetOrCreateTemporarySymbol method and a version that
takes a twine.

llvm-svn: 98118
 2010-03-10 01:29:27 +00:00
Chris Lattner bb592eb9d0 pass in more section kinds, enough to get the .align 0x90 
stuff to emit optimal nops in the right places.

llvm-svn: 97233
 2010-02-26 18:32:26 +00:00
Kevin Enderby 7f99302dc9 This is a patch to the assembler frontend to detect when aligning a text 
section with TextAlignFillValue and calls EmitCodeAlignment() instead of
calling EmitValueToAlignment().  This allows x86 assembly code to be aligned
with optimal nops.

llvm-svn: 97158
 2010-02-25 18:46:04 +00:00
Daniel Dunbar d0c6d361fe MC/AsmParser: Attempt to constant fold expressions up-front. This ensures we avoid fixups for obvious cases like '-(16)'. 
llvm-svn: 96064
 2010-02-13 01:28:07 +00:00
Chris Lattner d45adf28de wirte up .file and .file to the mc asmparser. 
llvm-svn: 94438
 2010-01-25 19:02:58 +00:00
Chris Lattner 807a3bcbbb fix a parsing problem on instructions like: 
movw	$8, (_cost_table_-L97$pb)+66(%eax)

After the parens, we could still have a binop.

llvm-svn: 94345
 2010-01-24 01:07:33 +00:00
Chris Lattner 685508cf49 move the various directive enums out of the MCStreamer class 
into a new MCDirectives.h file.

llvm-svn: 94294
 2010-01-23 06:39:22 +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
