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

Kevin Enderby ea9207cd7a Revert some unneeded parts of the change in r107886 for the 
.weak_def_can_be_hidden directive.  Chris pointed out that the MCAsmInfo.h/.cpp
chunks aren't needed for this until the compiler starts generating these.  And
when that happens it will be more convenient for it to be a bool than a const
char*.

llvm-svn: 107906
 2010-07-08 20:30:44 +00:00
Kevin Enderby 082d0fd7ad Added the darwin .weak_def_can_be_hidden directive.

Bill Wendling 3632171750 Revert r107205 and r107207. 
llvm-svn: 107215
 2010-06-29 22:34:52 +00:00
Bill Wendling 1767723dbe Introducing the "linker_weak" linkage type. This will be used for Objective-C 
metadata types which should be marked as "weak", but which the linker will
remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is
defined like this:

       .globl l_objc_msgSend_fixup_alloc
       .weak_definition l_objc_msgSend_fixup_alloc
       .section __DATA, __objc_msgrefs, coalesced
       .align 3
l_objc_msgSend_fixup_alloc:
        .quad   _objc_msgSend_fixup
        .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".

llvm-svn: 107205
 2010-06-29 21:24:00 +00:00
Duncan Sands a85a90773c The variable ValueSize is set to 1 on both code paths, and then 
ignored!  Remove it.

llvm-svn: 107138
 2010-06-29 13:30:08 +00:00
Duncan Sands 1245e4c07d The variable "Value" is carefully set to Layout.getSymbolAddress, 
but then not actually used - maybe a bug?  Remove the variable.

llvm-svn: 107137
 2010-06-29 13:26:33 +00:00
Duncan Sands 5667a08468 Remove unused calls to Lexer.getLoc and the pointless variable HasFillExpr. 
llvm-svn: 107136
 2010-06-29 13:24:40 +00:00

Thanks Daniel!

llvm-svn: 106608
 2010-06-22 23:51:47 +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

llvm-svn: 104651
 2010-05-26 00:02:12 +00:00
Daniel Dunbar 6738a2e39e llvm-mc: Use EmitIntValue where possible, which makes the API calls from the AsmParser and CodeGen line up better. 
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. 
llvm-svn: 104466
 2010-05-23 18:36:34 +00:00
Daniel Dunbar 3ff1a06de6 MC: Add an MCLoggingStreamer, for use in debugging integrated-as mismatches.

Fix up callers and users.

llvm-svn: 104057
 2010-05-18 21:16:04 +00:00
Kevin Enderby 7bcc9e9450 Incorporate Daniel's suggestion and use !isdigit(CurPtr[0]) and not 
CurPtr[0] == '\n' when testing the character after a "0b" when looking
to see if it part of a something like "jmp 0b".

llvm-svn: 104039
 2010-05-18 18:09:20 +00:00
Kevin Enderby 53e0631516 Fixed the problem with a branch to "0b" that was not parsed by llvm-mc 
correctly.  The Lexer was incorrectly eating the newline casusing it to branch
to address 0.  Updated the test case to use a "0:" label and a branch to "0b".

llvm-svn: 104038
 2010-05-18 17:51:35 +00:00
Daniel Dunbar d5563f420a MC/Mach-O: Implement support for setting indirect symbol table offset in section header. 
Also, create symbol data for LHS of assignment, to match 'as' symbol ordering better.

llvm-svn: 104033
 2010-05-18 17:28:24 +00:00
Daniel Dunbar f16c12d7a1 MC/Mach-O: Remove some FIXMEs. 
llvm-svn: 104032
 2010-05-18 17:28:20 +00:00
Daniel Dunbar 39617bb08a MC/Mach-O: Fail faster/harder when we see .file, which isn't yet supported. 
llvm-svn: 104031
 2010-05-18 17:28:17 +00:00
Benjamin Kramer ab7be75e3f Simplify MCContext::(Next|Get)Instance 
- Allocate MCLabels in the context so they don't leak.
- Avoid duplicated densemap lookup.

llvm-svn: 104020
 2010-05-18 12:15:34 +00:00
Kevin Enderby 0510b48fd9 Added support in MC for Directional Local Labels. 
llvm-svn: 103989
 2010-05-17 23:08:19 +00:00
Eric Christopher 9635b3da6b More data/parsing support for tls directives. Add a few more testcases 
and cleanup comments as well.

llvm-svn: 103985
 2010-05-17 22:53:55 +00:00
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 ce5e1bb326 MC: Add dyn_cast support to MCSection. 
- Of questionable utility, since in general anything which wants to do this should probably be within a target specific hook, which can rely on the sections being of the appropriate type. However, it can be useful for short term hacks.

llvm-svn: 103980
 2010-05-17 21:54:26 +00:00
Daniel Dunbar b7b796cc11 MC/Mach-O: Reverse order of SymbolData scanning when emitting instructions. 
- This fixes a string table mismatch with 'as' when two new symbols are defined
   in a single instruction.

llvm-svn: 103979
 2010-05-17 21:19:59 +00:00
Eric Christopher bf79238599 Add some section and constant support for darwin TLS. 
llvm-svn: 103974
 2010-05-17 21:02:07 +00:00
Daniel Dunbar 0211a96989 MC/Mach-O: Fix some differences in symbol flag handling. 
- Don't clear weak reference flag, 'as' was only "trying" to do this, it wasn't
   actually succeeding.
 - Clear the "lazy bound" bit when we mark something external. This corresponds
   roughly to the lazy clearing of the bit that 'as' implements in
   symbol_table_lookup.
 - The exact meaning of these flags appears pretty loose, since 'as' isn't very
   consistent. For now we just try to match 'as', we will clean this up one day
   hopefully.

llvm-svn: 103964
 2010-05-17 20:12:31 +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
Daniel Dunbar 2493ddfe42 MC/Mach-O/x86_64: Darwin's special "signed_N" relocation types should only be 
used to replace a normal relocation, not a reference to a GOT entry.

llvm-svn: 103789
 2010-05-14 18:53:40 +00:00
Eric Christopher 9fb6bb07ca Add AsmParser support for darwin tbss directive. 
Nothing uses this yet.

- The eliminates the last major algorithmic problem with MC.

llvm-svn: 103754
 2010-05-14 00:51:14 +00:00
Daniel Dunbar 9abade1017 MC: Extend MCAsmLayout to explicitly track which fragments have been layed out, and enforce several invariants to LayoutFragment to ensure we only do layout in a sensible order. 
llvm-svn: 103753
 2010-05-14 00:37:21 +00:00
Daniel Dunbar 3eedc26e18 MC: Implicitly assign section addresses when the previous fragment is layed out. 
llvm-svn: 103752
 2010-05-14 00:37:17 +00:00
Daniel Dunbar 8f9d2266e6 MC: Switch MCFragment to storing the layout order index, not its index in the file. 
llvm-svn: 103751
 2010-05-14 00:37:14 +00:00
Daniel Dunbar a99a23b061 MC: Change LayoutSection() to only do the section initializiation. 
Also, elimminate MCAsmLayout::set*, which are no longer needed.

llvm-svn: 103750
 2010-05-14 00:37:11 +00:00
Daniel Dunbar b9f6ac094a MC: Move Layout{Fragment,Section} into MCAsmLayout, and add LayoutFile(). 
llvm-svn: 103738
 2010-05-13 20:40:12 +00:00
Daniel Dunbar 454ea716a3 MC: Factor out MCAssembler::ComputeFragmentSize. 
llvm-svn: 103724
 2010-05-13 18:35:06 +00:00
