llvm-svn: 121072
 2010-12-06 23:57:07 +00:00
Rafael Espindola 0f30fec0bd Remove the instruction fragment to data fragment lowering since it was causing 
freed data to be read. I will open a bug to track it being reenabled.

Jason W Kim 29805961d8 ARM/MC/ELF relocation "hello world" for movw/movt. 
Lifted adjustFixupValue() from Darwin for sharing w ELF.
Test added
TODO:
  refactor ELFObjectWriter::RecordRelocation more.
  Possibly share more code with Darwin?
  Lots more relocations...

Jim Grosbach 2d3e5c1aec Fix handling of ARM negative pc-relative fixups for loads and stores.

Daniel Dunbar a5f50c16f7 MC/Mach-O: Switch to using MachOFormat.h. 
- I'm leaving MachO.h, because I believe it has external consumers, but I would really like to eliminate it (we have stylistic disagreements with one another).

Rafael Espindola bf4a4e4ad9 Remove the unused TheTarget member.

Rafael Espindola 7a2cd8b540 make isVirtualSection a virtual method on MCSection. Chris' suggestion.

Daniel Dunbar fe0c28f4db MC: Simplify Mach-O and ELF object writer implementations. 
- What was I thinking?????

Jim Grosbach 20b6fd7d5d Start of support for binary emit of 16-it Thumb instructions. 
llvm-svn: 118859
 2010-11-11 23:41:09 +00:00
Jim Grosbach 9d6d77a9f4 Encoding of destination fixup for ARM branch and conditional branch 
instructions.

llvm-svn: 118801
 2010-11-11 18:04:49 +00:00
Jim Grosbach 9b973490c9 ARM .word data fixups don't need an adjustment. 
llvm-svn: 118586
 2010-11-09 17:36:59 +00:00
Jim Grosbach 9098714f8b Add support for a few simple fixups to the ARM Darwin asm backend. This allows 
constant pool references and global variable refernces to resolve properly
for object file generation. For example,

int x;
void foo(unsigned a, unsigned *p) {
  p[a] = x;
}

can now be successfully compiled directly to an (ARM mode) object file.

Jim Grosbach 2bab7570f5 Enable MachO writing for ARM/Darwin. Lots of stuff still doesn't work 
(relocations, e.g.), but this will allow simple things to flow through.

llvm-svn: 118289
 2010-11-05 18:50:35 +00:00
Jim Grosbach 46c2acbcb4 Allow targets to specify the MachO CPUType/CPUSubtype information. 
llvm-svn: 118288
 2010-11-05 18:48:58 +00:00
Rafael Espindola 0ed1543d4e Add support for emitting ARM file attributes. 
llvm-svn: 117275
 2010-10-25 17:50:35 +00:00
Wesley Peck 1851090515 Making the e_machine configurable by the target backend in ELFObjectWriter. 
llvm-svn: 117099
 2010-10-22 15:52:49 +00:00
Rafael Espindola 4262a22225 Add a MCObjectFormat class so that code common to all targets that use a 
single object format can be shared.

This also adds support for

mov zed+(bar-foo), %eax

on ELF and COFF targets.

 2010-10-16 18:23:53 +00:00
Jim Grosbach 7e872969ce Move getPointerSize() to the base class since it's not dependent on MachO 
vs. ELF

llvm-svn: 115180
 2010-09-30 17:45:51 +00:00
Jim Grosbach 5a5ddc402e Remove extraneous ';' 
llvm-svn: 115176
 2010-09-30 17:19:17 +00:00
Kevin Enderby bad267fa05 Adds getPointerSize() to the AsmBackend which will be needed by the final patch 
for the dwarf .loc support to emit dwarf line number tables.

Jason W Kim 6c233c141e Fix two tiny issues (ARM does not need COFF) and comment sanity. 
llvm-svn: 115147
 2010-09-30 14:58:19 +00:00
Jim Grosbach 689651c767 trailing whitespace 
llvm-svn: 115136
 2010-09-30 03:21:00 +00:00
Jim Grosbach 58bce99385 Remove misplaced ';'. Make buildbots happy, hopefully. 
llvm-svn: 115135
 2010-09-30 03:20:34 +00:00
Jason W Kim b32124545b I added a new file ARMAsmBackend which stubs out in similar ways to 
the eqv X86 class.
For now, I split the ELFARMAsmBackend from the DarwinARMAsmBackend
(also mimicking X86)

Tested against -r115126
