Daniel Dunbar 96d812a68d build: Tidy up a bunch of tool Makefiles, and simplify where possible using the 
new all-targets pseudo-component.

Nick Lewycky 40f8f2ff24 Add support for a new extension to the .file directive: 
.file filenumber "directory" "filename"

This removes one join+split of the directory+filename in MC internals. Because
bitcode files have independent fields for directory and filenames in debug info,
this patch may change the .o files written by existing .bc files.

Chandler Carruth 2d71c421f9 Move the registered target printing in version strings completely out of 
the Support library. Now its part of the TargetRegistry, and the three
commands that care about this explicitly register this extra bit of
version information.

The set of commands which care was computed by intersecting those which
use the Support library's version string printing and those that
initialize all the registered targets in a way that produces
a meaningful list. The only odd ball out is that 'clang -cc1as -version'
no longer prints the registered targets. I don't think anyone is really
interested in that (especially as the fact that llvm-mc does so is under
a FIXME), but if someone really does want this back I'll happily apply
the same patch there.

Evan Cheng bbf3b0de8b Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc. 
There is still a bit more refactoring left to do in Targets. But we are now very
close to fixing all the layering issues in MC.

Evan Cheng efd9b4240f - Move CodeModel from a TargetMachine global option to MCCodeGenInfo. 
- Introduce JITDefault code model. This tells targets to set different default
  code model for JIT. This eliminates the ugly hack in TargetMachine where
  code model is changed after construction.

 2011-07-11 20:40:56 +00:00
Evan Cheng c5e6d2f519 - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfo 
and MCSubtargetInfo.
- Added methods to update subtarget features (used when targets automatically
  detect subtarget features or switch modes).
- Teach X86Subtarget to update MCSubtargetInfo features bits since the
  MCSubtargetInfo layer can be shared with other modules.
- These fixes .code 16 / .code 32 support since mode switch is updated in
  MCSubtargetInfo so MC code emitter can do the right thing.

 2011-07-11 03:57:24 +00:00
Evan Cheng 91111d2706 Change createAsmParser to take a MCSubtargetInfo instead of triple, 
CPU, and feature string. Parsing some asm directives can change
subtarget state (e.g. .code 16) and it must be reflected in other
modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance
must be shared.

llvm-svn: 134795
 2011-07-09 05:47:46 +00:00
Evan Cheng 4d1ca96bfc Eliminate asm parser's dependency on TargetMachine: 
- Each target asm parser now creates its own MCSubtatgetInfo (if needed).
- Changed AssemblerPredicate to take subtarget features which tablegen uses
  to generate asm matcher subtarget feature queries. e.g.
  "ModeThumb,FeatureThumb2" is translated to
  "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0".

Evan Cheng fe6e405e8c Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name to 
be the first encoded as the first feature. It then uses the CPU name to look up
features / scheduling itineray even though clients know full well the CPU name
being used to query these properties.

The fix is to just have the clients explictly pass the CPU name!

Bill Wendling b74b9de151 Use the verbose asm flag instead of a new flag for decoding the LSDA. 
llvm-svn: 133292
 2011-06-17 20:55:01 +00:00
Bill Wendling e303114b3c Add an option that allows one to "decode" the LSDA. 
The LSDA is a bit difficult for the non-initiated to read. Even with comments,
it's not always clear what's going on. This wraps the ASM streamer in a class
that retains the LSDA and then emits a human-readable description of what's
going on in it.

So instead of having to make sense of:

Lexception1:
        .byte   255
        .byte   155
        .byte   168
        .space  1
        .byte   3
        .byte   26
Lset0 = Ltmp7-Leh_func_begin1
      .long     Lset0
Lset1 = Ltmp812-Ltmp7
      .long     Lset1
Lset2 = Ltmp913-Leh_func_begin1
      .long     Lset2
      .byte     3
Lset3 = Ltmp812-Leh_func_begin1
      .long     Lset3
Lset4 = Leh_func_end1-Ltmp812
      .long     Lset4
      .long     0
      .byte     0
      .byte     1
      .byte     0
      .byte     2
      .byte     125
      .long     __ZTIi@GOTPCREL+4
      .long     __ZTIPKc@GOTPCREL+4

you can read this instead:

## Exception Handling Table: Lexception1
##  @LPStart Encoding: omit
##    @TType Encoding: indirect pcrel sdata4
##        @TType Base: 40 bytes
## @CallSite Encoding: udata4
## @Action Table Size: 26 bytes

## Action 1:
##   A throw between Ltmp7 and Ltmp812 jumps to Ltmp913 on an exception.
##     For type(s):  __ZTIi@GOTPCREL+4 __ZTIPKc@GOTPCREL+4
## Action 2:
##   A throw between Ltmp812 and Leh_func_end1 does not have a landing pad.

Chris Lattner 979634bbb0 start straightening out libedis's dependencies and make it fit 
better in the llvm world.  Among other things, this changes:

1. The guts of libedis are now moved into lib/MC/MCDisassembler
2. llvm-mc now depends on lib/MC/MCDisassembler, not tools/edis,
   so edis and mc don't have to be built in series.
3. lib/MC/MCDisassembler no longer depends on the C api, the C
   API depends on it.
4. Various code cleanup changes. 

There is still a lot to be done to make edis fit with the llvm
design, but this is an incremental step in the right direction.

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,

EH, we can switch it off.

Sean Callanan 177934e021 Changed the AsmParser to handle error messages itself

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

This requires new/deleting all the operands, but it also gives 
targets the ability to use polymorphic operands if they want to.
