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.

828984ff4e MC/AsmParser: Add .macros_{off,on} support, not that makes sense since we don't 
support macros.

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.

classes which want to extend the basic asm parser.

e233dda2e2 Added the darwin .secure_log_unique and .secure_log_reset directives.

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

ec9d6faef0 Add support for parsing the ELF .type assembler directive.

5c87be766d Make EmitTBSSSymbol take a section argument so that we can find it later. 
Fix up callers and users.

9635b3da6b More data/parsing support for tls directives. Add a few more testcases 
and cleanup comments as well.

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

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.

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

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.
