Rafael Espindola 3c227b0b89 Add basic CFI methods to the streamer interface. 
llvm-svn: 119972
 2010-11-22 14:27:24 +00:00
Kevin Enderby 8be14414f6 Added support for the Mach-O .symbol_resolver directive. rdar://8673046

Rafael Espindola 92ca933f6e Fix llvm-gcc boostrap on OS X by avoiding printing sleb and uleb when 
possible.

llvm-svn: 119785
 2010-11-19 04:10:13 +00:00
Rafael Espindola b58867ccba Change some methods in MCDwarf.cpp to be able to handle an arbitrary 
MCStreamer instead of just MCObjectStreamer. Address changes cannot
be as efficient as we have to use DW_LNE_set_addres, but at least
most of the logic is shared.

This will be used so that, with CodeGen still using EmitDwarfLocDirective,
llvm-gcc is able to produce debug_line sections without needing an
assembler that supports .loc.

llvm-svn: 119777
 2010-11-19 02:26:16 +00:00
Rafael Espindola c653a895c8 Add .loc methods to the streamer. 
Next: Add support for the !HasDotLocAndDotFile case to the MCAsmStreamer
and then switch codegen to use it.

Small test for sanity check of resulting ARM .s file.
Tested against -r115129.

llvm-svn: 115133
 2010-09-30 02:45:56 +00:00
Chris Lattner 7bce0596a7 allow target-specific label suffixes, patch by Yuri Gribov! 
llvm-svn: 114592
 2010-09-22 22:19:53 +00:00
Jim Grosbach 6ebd728067 grammar tweakage 
llvm-svn: 114561
 2010-09-22 18:18:30 +00:00
Jim Grosbach 3bde49aa29 remove trailing whitespace 
llvm-svn: 114560
 2010-09-22 18:16:55 +00:00
Rafael Espindola f667d929ce Add a InitSections method to the streamer interface. 
The ELF implementation now creates text, data and bss to match the gnu as
behavior.

The text streamer still has the old MachO specific behavior since
the testsuite checks that it will error when a directive is given
before a setting the current section for example.

A nice benefit is that -n is not required anymore when producing
ELF files.

llvm-svn: 114027
 2010-09-15 21:48:40 +00:00
Benjamin Kramer e39017cb97 Add AsmParser support for the ELF .previous directive. Patch by Roman Divacky. 
llvm-svn: 112849
 2010-09-02 18:53:37 +00:00
Benjamin Kramer a3e0ddb564 Plug the remaining MC leaks by giving MCObjectStreamer/MCAsmStreamer ownership of the TargetAsmBackend and the MCCodeEmitter. 
llvm-svn: 109767
 2010-07-29 17:48:06 +00:00
Kevin Enderby 082d0fd7ad Added the darwin .weak_def_can_be_hidden directive. 
llvm-svn: 107886
 2010-07-08 17:22:42 +00:00
Chris Lattner 79d2075e4a "This is just a cosmetic change in MCAsmStreamer.cpp/EmitSymbolAttribute: all attributes have now a \t before and after, as done for '.type'. 
This makes the output look consistent, as well as help some third party assemblers expecting the attributes to be in the second column."

Patch by Arnaud de Grandmaison!

llvm-svn: 106469
 2010-06-21 20:35:01 +00:00
Dan Gohman a76715fc88 Don't call flush() at a library level which isn't checking for errors 
and doesn't know where the output is going.

llvm-svn: 105274
 2010-06-01 16:31:34 +00:00
Daniel Dunbar 3627af5da4 MC: Change MCInst::dump_pretty to not include a trailing newline. 
llvm-svn: 104696
 2010-05-26 15:18:13 +00:00
Eric Christopher 5c87be766d Make EmitTBSSSymbol take a section argument so that we can find it later. 
Fix up callers and users.

llvm-svn: 104057
 2010-05-18 21:16:04 +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. 
Nothing uses this yet.

 2010-05-14 01:50:28 +00:00
Chris Lattner 72afa956db break coff symbol definition stuff out into proper MCStreamer callbacks, 
patch by Nathan Jeffords!

llvm-svn: 103346
 2010-05-08 19:54:22 +00:00
Daniel Dunbar f3a53baf00 MC/Mach-O: Mark absolute variable's appropriately, and add Mach-O support for 
writing them.
 - <rdar://problem/7885351> integrated assembler broken for i386 objc code

llvm-svn: 103112
 2010-05-05 19:01:05 +00:00

llvm-svn: 103111
 2010-05-05 19:01:00 +00:00
Daniel Dunbar 7a989da0af MC: Rename MCSymbol::{g,s}etValue -> MCSymbol::{g,s}etVariableValue. 
llvm-svn: 103095
 2010-05-05 17:41:00 +00:00
Chris Lattner 7012916275 fix an ugly wart in the MCInstPrinter api where the 
raw_ostream to print an instruction to had to be specified
at MCInstPrinter construction time instead of being able
to pick at each call to printInstruction.

llvm-svn: 100307
 2010-04-04 05:04:31 +00:00
Chris Lattner aca014e24e allow attaching comments to raw text. 
llvm-svn: 100292
 2010-04-03 22:06:56 +00:00
Chris Lattner 8a87fb7633 add a new EmitInlineAsm function to asmprinter to handle inline asm. 
If we have an MCAsmStreamer, we continue to emit asm textually, 
otherwise we (currently) emit an error to errs and ignore it.

llvm-svn: 100289
 2010-04-03 21:35:55 +00:00
Daniel Dunbar 04047fbe14 MCInst: Add ::dump_pretty. 
llvm-svn: 99216
 2010-03-22 21:49:34 +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
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 eebaf6a76f genericize MCAsmStreamer::EmitCodeAlignment to support other targets 
so that it doesn't break them when the code generator starts using it.

llvm-svn: 96966
 2010-02-23 18:44:31 +00:00
Kevin Enderby e83d74f626 This is the first patch to put the needed bits in place to eventually allow code 
to be aligned with optimal nops.  This patch does not change any functionality
and when the compiler is changed to use EmitCodeAlignment() it should also not
change the resulting output.  Once the compiler change is made and everything
looks good the next patch with the table of optimal X86 nops will be added to
WriteNopData() changing the output.  There are many FIXMEs in this patch which
will be removed when we have better target hooks (coming soon I hear).

llvm-svn: 96963
 2010-02-23 18:26:34 +00:00
Chris Lattner 524138176d add a new MCInstPrinter::getOpcodeName interface, when it is 
implemented, llvm-mc --show-inst now uses it to print the
instruction opcode as well as the number.

llvm-svn: 95929
 2010-02-11 22:39:10 +00:00
Chris Lattner ddeceae839 make getFixupKindInfo return a const reference, allowing 
the tables to be const.  Teach MCCodeEmitter to handle
the target-indep kinds so that we don't crash on them.

llvm-svn: 95924
 2010-02-11 21:27:18 +00:00
Daniel Dunbar 605474463f MC: Switch MCFixup to just hold an MCExpr pointer instead of index into the 
MCInst it came from.

llvm-svn: 95767
 2010-02-10 04:47:08 +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

Chris Lattner 69920c5c8a daniel *really* likes fixups! 
llvm-svn: 95742
 2010-02-10 01:05:28 +00:00
Chris Lattner 482bf69bfe Add ability for MCInstPrinters to add comments for instructions. 
Enhance the x86 backend to show the hex values of immediates in
comments when they are large.  For example:

        movl    $1072693248, 4(%esp)    ## imm = 0x3FF00000

 2010-02-09 22:59:55 +00:00
Chris Lattner 89261502cb make -show-inst be formatted a bit nicer. Before: 
movl	$3735928559, a          ## inst: <MCInst 1273 <MCOperand Reg:0> <MCOperand Imm:1> <MCOperand Reg:0> <MCOperand Expr:(a)> <MCOperand Reg:0> <MCOperand Expr:(3735928559)>>

after:

	movl	$3735928559, a          ## <MCInst #1273
                                        ##   <MCOperand Reg:0>

Chris Lattner 175629608e print encodings like this: 
pslld	69, %mm3                ## encoding: [0x0f,0xf2,0x1c,0x25,0x45,0x00,0x00,0x00]

instead of like this:
	pslld	69, %mm3                ## encoding: [0x0f,0xf2,0x1c,0x25,0x45,0000,0000,0000]

this only affects 0.

llvm-svn: 95441

Dan Gohman 77fe07a93a Use a tab instead of space after .type, for consistency. 
llvm-svn: 95272
