Bill Wendling d749aefbd5 Comment the changes for r98218 and friends inside the source code. 
llvm-svn: 100033
 2010-03-31 18:48:58 +00:00
Jakob Stoklund Olesen 9986ba954c Replace V_SET0 with variants for each SSE execution domain.

Chris Lattner 9897043928 Rip out the 'is temporary' nonsense from the MCContext interface to 
create symbols.  It is extremely error prone and a source of a lot
of the remaining integrated assembler bugs on x86-64.

This fixes rdar://7807601.

llvm-svn: 99902
 2010-03-30 18:10:53 +00:00
Chris Lattner aed00fa039 fix GetOrCreateTemporarySymbol to require a name, clients 
should use CreateTempSymbol() if they don't care about the
name.

Daniel Dunbar 5599256415 MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr. 
- Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue.
 - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol.

Chris Lattner 87dd2d6388 comment fix. 
llvm-svn: 98494
 2010-03-14 17:10:52 +00:00
Chris Lattner 28aae17fee shrink 4-byte branches to 1-byte branches when lowering from 
MachineInstr -> MCInst.  This is what the assembler backend wants,
it relaxes from smaller to larger things.  This fixes rdar://7750815

llvm-svn: 98493
 2010-03-14 17:04:18 +00:00
Chris Lattner 29bdac4928 eliminate the now-unneeded context argument of MBB::getSymbol() 
llvm-svn: 98451
 2010-03-13 21:04:28 +00:00
Chris Lattner e468f88b26 rearrange MCContext ownership. Before LLVMTargetMachine created it 
and passing off ownership to AsmPrinter.  Now MachineModuleInfo
creates it and owns it by value.  This allows us to use MCSymbols
more consistently throughout the rest of the code generator, and
simplifies a bit of code.  This also allows MachineFunction to 
keep an MCContext reference handy, and cleans up the TargetRegistry
interfaces for AsmPrinters.

 2010-03-13 20:55:24 +00:00
Chris Lattner 81fe45d911 switch to the text section at the start of the .s file for darwin/x86 
targets.  This is a temporary hack for the .o file writer that Daniel
wants :)

Jeffrey Yasskin 9eeda13a52 Fix LLVM build when the user specifies CPPFLAGS on the make command line.

llvm-svn: 98391
 2010-03-12 21:21:19 +00:00
Chris Lattner 0b822ab447 inline GetGlobalValueSymbol into the rest its callers and 
remove it.

llvm-svn: 98390
 2010-03-12 21:19:23 +00:00
Chris Lattner 9e4cafe6f1 inline the now-trivial implementation of GetGlobalValueSymbol into 
some of its callers.

llvm-svn: 98388
 2010-03-12 21:09:07 +00:00
Chris Lattner e80055f8fc eliminate the X86 version of GetGlobalValueSymbol, allowing 
it to be non-virtual and soon disappear.

 2010-03-12 21:06:41 +00:00
Chris Lattner 8d99c764d3 move fastcall/stdcall mangling up into Mangler. 
llvm-svn: 98384

llvm-svn: 98377
 2010-03-12 20:43:52 +00:00
Chris Lattner 74026ffcae minor tidying, only do work if a function is 
actually X86_StdCall or X86_FastCall.

llvm-svn: 98374
 2010-03-12 19:48:03 +00:00

definitions.

llvm-svn: 98368
 2010-03-12 19:14:18 +00:00
Chris Lattner 6428db5089 use Mang->getSymbol instead of duplicating the logic, reduce indentation. 
llvm-svn: 98367
 2010-03-12 19:04:14 +00:00
Chris Lattner d75813970a simplify code to use OutContext.GetOrCreateTemporarySymbol with 
no arguments instead of having to come up with a unique name.
This also makes the code less fragile.

llvm-svn: 98364
 2010-03-12 18:47:50 +00:00
Bill Wendling a810bdfcca Add a bit along with the MCSymbols stored in the MachineModuleInfo maps that 
indicates that an MCSymbol is external or not. (It's true if it's external.)
This will be used to specify the correct information to add to non-lazy
pointers. That will be explained further when this bit is used.

llvm-svn: 98199
 2010-03-10 22:34:10 +00:00
Chris Lattner ac2361a9b0 set the temporary bit on MCSymbols correctly.

Chris Lattner b1913c4df9 enhance llvm-mc -show-inst to print the enum of an instruction, like so: 
testb	%al, %al                ## <MCInst #2412 TEST8rr
                                        ##   <MCOperand Reg:2>
                                        ##   <MCOperand Reg:2>>
	jne	LBB1_7                  ## <MCInst #938 JNE_1
                                        ##   <MCOperand Expr:(LBB1_7)>>

Chris Lattner 482bf69bfe Add ability for MCInstPrinters to add comments for instructions. 
Enhance the x86 backend to show the hex values of immediates in
comments when they are large.  For example:

        movl    $1072693248, 4(%esp)    ## imm = 0x3FF00000

 2010-02-10 00:10:18 +00:00
Chris Lattner b06015aa69 move target-independent opcodes out of TargetInstrInfo 
into TargetOpcodes.h.  #include the new TargetOpcodes.h
into MachineInstr.  Add new inline accessors (like isPHI())
to MachineInstr, and start using them throughout the 
codebase.

instead of textually.

Chris Lattner 082f484074 make MachineModuleInfoMachO hold non-const MCSymbol*'s instead 
of const ones.  non-const ones aren't very useful, because you can't
even, say, emit them.
