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.

Chris Lattner 76c564b1bb change a ton of code to not implicitly use the "O" raw_ostream 
member of AsmPrinter.  Instead, pass it in explicitly.

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.

Sanjiv Gupta 7828ff9535 Currently in LLVM, names of libcalls are assigned during TargetLowering 
object construction. There is no provision to change them when the 
code for a function generated. 
So we have to change these names while printing assembly.

Sanjiv Gupta adcee844ea The code section for an ISR has a specific address. 
Currently, whether a function is ISR or not is encoded in the section attribute for that function.

Chris Lattner b0d44c3807 refactor code so that LLVMTargetMachine creates the asmstreamer and 
mccontext instead of having AsmPrinter do it.  This allows other 
types of MCStreamer's to be passed in.

Chris Lattner d051af7551 add a new MachineBasicBlock::getSymbol method, replacing 
the AsmPrinter::GetMBBSymbol.

Chris Lattner 170442fa12 don't bother setting the AsmPrinter::MF ivar, now that 
AsmPrinter::SetupMachineFunction sets it.  Note that systemz
and msp430 didn't.  Yay for reduced inconsistency! :)

 2010-01-26 04:38:11 +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.

David Greene 659c1a9d78 Move DebugInfo checks into EmitComments and remove them from 
target-specific AsmPrinters.  Not all comments need DebugInfo.

Re-enable the line numbers comment test.

Chris Lattner 1448799377 fix warning. 
llvm-svn: 84826
 2009-10-22 03:42:27 +00:00
Sanjiv Gupta 47ea743618 Add a pass to overlay pic16 data sections for function frame and automatic 
variables. This pass can be invoked by llvm-ld or opt to traverse over the call graph 
to detect what function frames and their automatic variables can be overlaid.
Currently this builds an archive , but needs to be changed to a loadable module.

Dan Gohman 10d3dc569b Instead of printing unnecessary basic block labels as labels in 
verbose-asm mode, print comments instead. This eliminates a non-comment
difference between verbose-asm mode and non-verbose-asm mode.

Also, factor out the relevant code out of all the targets and into
target-independent code.

Devang Patel 051454a16f Update processDebugLoc() so that it can be used to process debug info before and after printing an instruction. 
llvm-svn: 83363
 2009-10-06 02:19:11 +00:00
Devang Patel e0709cfc92 Use MachineInstr as an processDebugLoc() argument. 
This will allow processDebugLoc() to handle scopes for DWARF debug info.

Chris Lattner 1d04aa78f3 replace printBasicBlockLabel with EmitBasicBlockStart, 
now that printBasicBlockLabel is only used for starting
a MBB.  This allows elimination of a bunch of arguments.

llvm-svn: 81684
 2009-09-13 18:25:37 +00:00
Chris Lattner 4cd449813a convert some uses of printBasicBlockLabel to use GetMBBSymbol 
instead.

Chris Lattner 321bc99a74 remove DebugLoc from MCInst and eliminate "Comment printing" from 
the MCInst path of the asmprinter.  Instead, pull comment printing
out of the autogenerated asmprinter into each target that uses the
autogenerated asmprinter.  This causes code duplication into each
target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.

This also fixes an xcore strangeness where it inserted two tabs
before every instruction.

Sanjiv Gupta 9ae3bcb79e Add a pass to do call graph analyis to overlay the autos and frame sections of 
leaf functions. This pass will be extended to color other nodes of the call tree 
as well in future.

Sanjiv Gupta 686e9f55dc Implement support for ISRs. 
Clone functions that are shared between the Main thread and Interrupt thread.
CallSites are changed in AsmPrinter currently. A better solution would have been to modify the legalizer (SoftenFloat) to allow targets to change the name of libcalls for float operations. But that currently breaks other targets.
Also, cloing of automatic variables is done AsmPrinter, a better approach would
be to use the ValueMap in CloneFunction itself.

llvm-svn: 79562
 2009-08-20 19:28:24 +00:00
Chris Lattner 4b7dadb76e eliminate AsmPrinter::SwitchToSection and just have clients 
talk to the MCStreamer directly instead.
