them for consistency.

Chris Lattner c334d80b0d minor tidying. 
llvm-svn: 100338
 2010-04-04 18:16:38 +00:00
Chris Lattner 4a4710a055 clean up the asmprinter interface a bit, rename a few 
"Print" methods to "Emit".  Emit is something that goes
to an mc streamer, Print is something that goes to a
raw_ostream (for inline asm) 

llvm-svn: 100337
 2010-04-04 18:14:01 +00:00
Chris Lattner 21dc46e256 remove TargetMachine.h #include, also, TRI isn't used frequently 
enough to warrant caching in AsmPrinter, so remove it.

llvm-svn: 100336
 2010-04-04 18:06:11 +00:00
Chris Lattner 2cf5f9ec05 lazily allocate the GCMetadataPrinters map and remove DenseMap 
from the AsmPrinter interface.

 2010-04-04 17:57:56 +00:00
Chris Lattner d20699bc87 Momentous day: remove the "O" member from AsmPrinter. Now all 
"asm printering" happens through MCStreamer.  This also 
Streamerizes PIC16 debug info, which escaped my attention.

This removes a leak from LLVMTargetMachine of the 'legacy'
output stream.

llvm-svn: 100327
 2010-04-04 08:18:47 +00:00
Chris Lattner 462720b1b6 now that all operand printing happens to specified streams, we can 
print function level inline asm with EmitInlineAsm instead of writing
it directly to "O".

llvm-svn: 100326
 2010-04-04 07:50:12 +00:00
Chris Lattner 1198002c81 remove the raw_ostream from various dwarf printing things. 
The only thing left is LEB printing, which uses EmitRawText
for now.

llvm-svn: 100325
 2010-04-04 07:48:20 +00:00
Chris Lattner ef8240bbac mcize the gc metadata printing stuff. 
llvm-svn: 100324
 2010-04-04 07:39:04 +00:00
Chris Lattner dd89ce9a82 use EmitRawText instead of O in DwarfPrinter. 
llvm-svn: 100323
 2010-04-04 07:25:52 +00:00
Chris Lattner 3bb09768cb fix PrintAsmOperand and PrintAsmMemoryOperand to pass down 
raw_ostream to print to.

llvm-svn: 100313
 2010-04-04 05:29:35 +00:00
Chris Lattner 0124fe38a6 change this back too

 2010-04-04 05:08:10 +00:00
Chris Lattner f64c982943 MMI is always available, rename O -> OS in printInlineAsm. 
llvm-svn: 100308
 2010-04-04 05:07:45 +00:00
Chris Lattner 76c564b1bb change a ton of code to not implicitly use the "O" raw_ostream 
member of AsmPrinter.  Instead, pass it in explicitly.

llvm-svn: 100306
 2010-04-04 04:47:45 +00:00
Chris Lattner f33c7fcc28 asmstreamerize the .size directive for function bodies, force clients 
of printOffset to pass in a stream to print to.

llvm-svn: 100296

Chris Lattner c6d67d4ca5 emit the cygwin stub thing through mcstreamer. 
llvm-svn: 100295
 2010-04-03 22:19:41 +00:00
Chris Lattner 1716721df1 add a twine form of MCStreamer::EmitRawText, and mc'ize 
a few more things in AsmPrinter.cpp.

llvm-svn: 100294
 2010-04-03 22:12:35 +00:00
Chris Lattner 86d61b5837 start moving towards emitting inline asm statements with 
EmitInlineAsm.  However, this attempt is foiled by operands
being emitted directly to "O" so I'll have to do some surgery
and finish MCizing the world.

llvm-svn: 100291
 2010-04-03 22:01:50 +00:00
Chris Lattner 8a87fb7633 add a new EmitInlineAsm function to asmprinter to handle inline asm. 
If we have an MCAsmStreamer, we continue to emit asm textually, 
otherwise we (currently) emit an error to errs and ignore it.

llvm-svn: 100289
 2010-04-03 21:35:55 +00:00
Chris Lattner fed39fa7b3 mc'ize comment printing around file scope inline asm. 
llvm-svn: 100288
 2010-04-03 21:13:18 +00:00
Chris Lattner 915c5f9862 Switch the code generator (except the JIT) onto the new DebugLoc 
representation.  This eliminates the 'DILocation' MDNodes for 
file/line/col tuples from -O0 -g codegen.

This remove the old DebugLoc class, making it a typedef for DebugLoc,
I'll rename NewDebugLoc next.

I didn't update the JIT to use the new apis, so it will continue to
work, but be as slow as before.  Someone should eventually do this
or, better yet, rip out the JIT debug info stuff and build the JIT
on top of MC.

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
Devang Patel bd477bef25 Refactor code to push DILocation prcessing into DwarfDebug.cpp from AsmPrinter.cpp. 
This is same as r99772 (which was reverted) with just one meaningful difference where two source lines exchanged their positions.

llvm-svn: 99816
 2010-03-29 17:20:31 +00:00
Devang Patel 1e8ccb5f8b Revert 99772.

Devang Patel 32bdaef3fe Refactoring. Push DILocation processing in to DwarfDebug from AsmPrinter.

Chris Lattner 8fce3dddfa reapply r98656 unmodified, which exposed the asmprinter not 
handling constant unions.

llvm-svn: 98680
 2010-03-16 21:25:55 +00:00
Daniel Dunbar 3a374da973 Revert r98656, its breaking all over the place. 
llvm-svn: 98662
 2010-03-16 19:35:34 +00:00
Chris Lattner 9ae99e0df5 improve support for uniontype and ConstantUnion, patch by Tim Northover! 
llvm-svn: 98656
 2010-03-16 19:15:03 +00:00
Chris Lattner db035a0af2 Fix the third (and last known) case of code update problems due 
to LLVM IR changes with addr label weirdness.  In the testcase, we
generate references to the two bb's when codegen'ing the first
function:

_test1:                                 ## @test1
	leaq	Ltmp0(%rip), %rax
..
	leaq	Ltmp1(%rip), %rax

Then continue to codegen the second function where the blocks
get merged.  We're now smart enough to emit both labels, producing
this code:

_test_fun:                              ## @test_fun
## BB#0:                                ## %entry
Ltmp1:                                  ## Block address taken
Ltmp0:
## BB#1:                                ## %ret
	movl	$-1, %eax
	ret

Rejoice.

Chris Lattner 561334a81f Implement support for the case when a reference to a addr-of-bb 
label is generated, but then the block is deleted.  Since the
value is undefined, we just emit the label right after the entry 
label of the function.  It might matter that the label is in the
same section as the function was afterall.

 2010-03-15 20:39:00 +00:00
Devang Patel a3e9c9ca7b Emit dwarf variable info communicated by code generator through DBG_VALUE machine instructions. 
This is a work in progress.

llvm-svn: 98526
 2010-03-15 00:00:42 +00:00
Chris Lattner 9efbbcbe45 fix AsmPrinter::GetBlockAddressSymbol to always return a unique 
label instead of trying to form one based on the BB name (which
causes collisions if the name is empty).  This fixes PR6608

llvm-svn: 98495
 2010-03-14 17:53:23 +00:00
Chris Lattner c26f44fb07 change the DBG_LABEL MachineInstr to always be created 
with an MCSymbol instead of an immediate.

llvm-svn: 98481
 2010-03-14 07:56:48 +00:00
Chris Lattner 1065f49ad9 switch GC_LABEL to use an MCSymbol operand instead of a label ID operand. 
llvm-svn: 98474
 2010-03-14 07:27:07 +00:00
Chris Lattner ee2fbbc978 change the LabelSDNode to be EHLabelSDNode and make it hold 
an MCSymbol.  Make the EH_LABEL MachineInstr hold its label
with an MCSymbol instead of ID.  Fix a bug in MMI.cpp which
would return labels named "Label4" instead of "label4".

llvm-svn: 98463
 2010-03-14 02:33:54 +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.

Chris Lattner 9e4cafe6f1 inline the now-trivial implementation of GetGlobalValueSymbol into 
some of its callers.

Chris Lattner c7b46f9d9c give Mangler access to TargetData. 
llvm-svn: 98378
 2010-03-12 20:47:28 +00:00
Chris Lattner be3242b523 finally give Mangler a getSymbol method, which returns an MCSymbol 
for a global instead of messing around with string buffers.

llvm-svn: 98366
 2010-03-12 18:55:20 +00:00
Chris Lattner 2eff505fba make the mangler take an MCContext instead of an MAI. 
No functionality change.
