Chris Lattner 1edfeb2c46 don't forget to initialize an instance variable! 
llvm-svn: 94021
 2010-01-20 20:48:59 +00:00
Chris Lattner 9fc980403e use getGlobalDirective(), don't hardcode .globl. PR6093 
llvm-svn: 94006
 2010-01-20 17:50:30 +00:00
Chris Lattner 45eeffcc2a make mcasmstreamer handle expanding 8 byte integer constants to 
4-byte constants if .quad isn't supported.  Switch a bunch of
methods used by the dwarf writer to use OutStreamer.EmitIntValue.

llvm-svn: 93987
 2010-01-20 06:45:39 +00:00
Chris Lattner 38caaf14c1 give createAsmStreamer an 'isLittleEndian' argument. 
llvm-svn: 93986
 2010-01-20 06:39:07 +00:00
Chris Lattner 2b4364fe03 revert 93934, removing the MCAsmInfo endianness bit. I can't 
stomache MCAsmInfo having this, and I found a better solution to
this layering issue.

llvm-svn: 93985
 2010-01-20 06:34:14 +00:00
Chris Lattner 003b5c8472 give MCAsmInfo a 'has little endian' bit. This is unfortunate, but 
I really want clients of the streamer to be able to say "emit this
64-bit integer" and have it get broken down right by the streamer.

I may change this in the future, we'll see how it works out.

llvm-svn: 93934
 2010-01-19 22:42:28 +00:00
Chris Lattner dc50e5d128 add a new EmitIntValue method that MCStreamer impls can optionally define 
and that clients can use.

llvm-svn: 93923
 2010-01-19 22:03:38 +00:00
Sean Callanan 936b0d3144 Promoted the getTok() method to MCAsmParser so that 
the two token accessor functions are declared consistently.
Modified the clients of MCAsmParser to reflect this change.

llvm-svn: 93916
 2010-01-19 21:44:56 +00:00
Chris Lattner c35681b298 Generalize mcasmstreamer data emission APIs to take an address space 
identifier.  There is no way to work around it.

llvm-svn: 93896
 2010-01-19 19:46:13 +00:00
Chris Lattner ed89f60f5e mcstreamerize AsmPrinter::EmitZeros, at least when emitting to the 
default address space.

llvm-svn: 93890
 2010-01-19 18:58:52 +00:00
Chris Lattner 4340cb3246 add an MCAsmStreamer::EmitFill specialization of EmitFill that 
emits one directive instead of N.  Not doing this would be a
significant regression on the # bytes generated by .fill.

llvm-svn: 93889
 2010-01-19 18:52:28 +00:00
Chris Lattner 0c65fd4902 add a "MCStreamer::EmitFill" method, and move the default implementation 
(which just iteratively emits bytes) to MCStreamer.

llvm-svn: 93888
 2010-01-19 18:45:47 +00:00
Chris Lattner 9c31b0c695 remove MAI::ZeroDirectiveSuffix, which is only used by MASM, 
which we don't support anymore.

llvm-svn: 93886
 2010-01-19 18:37:01 +00:00
Chris Lattner cd2915e467 stop using the .lcomm pseudoop on darwin, instead, directly use the 
.zerofill directive.  Streamerize its generation.

llvm-svn: 93868
 2010-01-19 06:25:51 +00:00
Chris Lattner 95b98959b0 mc'ize some stuff, don't comment out .lcomm directive in -fverbose-asm mode. 
llvm-svn: 93860
 2010-01-19 06:01:04 +00:00
Chris Lattner b1f2934fc7 hookize the cygwin ".linkonce" directive. 
llvm-svn: 93855
 2010-01-19 05:08:13 +00:00
Chris Lattner dccbb28bca add a bool for whether .lcomm takes an alignment instead of basing this on "isdarwin". 
llvm-svn: 93852
 2010-01-19 04:48:20 +00:00
Chris Lattner e9d28b19cf move production of .reference directives for static ctor/dtor list on 
darwin into common code.

llvm-svn: 93849
 2010-01-19 04:34:02 +00:00
Chris Lattner 1d371882b6 Cleanup handling of .zerofill on darwin: 
1. TargetLoweringObjectFileMachO should decide if something
   goes in zerofill instead of having every target do it.
2. TargetLoweringObjectFileMachO should assign said symbols to
   the right MCSection, the asmprinters should just emit to the
   right section.
3. Since all zerofill stuff goes through mcstreamer anymore,
   MAI can have a bool "haszerofill" instead of having the textual
   directive to emit.

Nate Begeman e945172ba4 Remove this fixme, looking at the linker source, all targets pad to 4 bytes. 
llvm-svn: 93835
 2010-01-19 01:32:44 +00:00
Chris Lattner c8f7717808 remove the MAI argument to MCExpr::print and switch overthing to use << when printing them. 
llvm-svn: 93699
 2010-01-18 00:37:40 +00:00
Chris Lattner 8b5d55ed06 now that MCSymbol::print doesn't use it's MAI argument, we can 
remove it and change all the code that prints MCSymbols to use 
<< instead, which is much simpler and cleaner.

llvm-svn: 93695
 2010-01-17 21:43:43 +00:00
Chris Lattner 043e656797 rename NameNeedsEscaping -> NameNeedsQuoting, eliminate the check 
for first character which is a digit, mangler would have taken care
of this already.

llvm-svn: 93694
 2010-01-17 20:11:03 +00:00
Chris Lattner 83e872e1c4 Get MCSymbol out of the mangling business, and move all the logic 
to Mangler.  Now MCSymbol just decides whether to slap quotes around
a symbol when printing it.

This also fixes some weirdness where two MCSymbols could be created
for the same symbol, if one needed to be mangled and got mangled to
the other one.

llvm-svn: 93690
 2010-01-17 19:23:46 +00:00
Nate Begeman 660d979ad9 Add a note for the macho streamer and remove a used of the mangler from the soon to be defunct machowriter pass.

Chris Lattner 528d00b913 extend MCAsmParser::ParseExpression and ParseParenExpression 
to return range information for subexpressions.  Use this to
provide range info for several new X86Operands.

Chandler Carruth 56869f22c4 Move DataTypes.h to include/llvm/System, update all users. This breaks the last 
direct inclusion edge from System to Support.

Kevin Enderby 818b6b96cb Fixed MCSectionMachO::ParseSectionSpecifier to allow an attribute of "none" so 
that a symbol stub section with no attributes can be parsed as in:
.section __TEXT,__picsymbolstub4,symbol_stubs,none,16

Anton Korobeynikov 592638ae05 Allow symbols to start from the digit if target requests it. This allows, e.g. pinning 
variables to specified absolute address. Make use of this feature for MSP430.
This unbreaks PR4776.

Chris Lattner b866602f06 Big change #1 for personality function references: 
Eliminate the PersonalityPrefix/Suffix & NeedsIndirectEncoding
fields from MAI: they aren't part of the asm syntax, they are
related to the structure of the object file.

To replace their functionality, add a new 
TLOF::getSymbolForDwarfGlobalReference method which asks targets
to decide how to reference a global from EH in a pc-relative way.

The default implementation just returns the symbol.  The default
darwin implementation references the symbol through an indirect
$non_lazy_ptr stub.  The bizarro x86-64 darwin specialization
handles the weird "foo@GOTPCREL+4" hack.

DwarfException.cpp now uses this to emit the reference to the
symbol in the right way, and this also eliminates another 
horrible hack from DwarfException.cpp:

-    if (strcmp(MAI->getPersonalitySuffix(), "+4@GOTPCREL"))
-      O << "-" << MAI->getPCSymbol();

llvm-svn: 81991
