PR4841.  Patch by Craig Smith!

 2010-03-14 18:31:44 +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 87dd2d6388 comment fix.

 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

Chris Lattner 6e52e9db31 get MMI out of the label uniquing business, just go to MCContext 
to get unique assembler temporary labels.

Chris Lattner d5e8d9f29a Now that DBG_LABEL is updated, we can finally make MachineMove 
contain an MCSymbol instead of a label index.

 2010-03-14 08:12:40 +00:00
Chris Lattner c26f44fb07 change the DBG_LABEL MachineInstr to always be created 
with an MCSymbol instead of an immediate.

Daniel Dunbar aa8f95eb56 MC: Fix a crash on invalid, attempting to evaluate undefined symbols. 
llvm-svn: 98464
 2010-03-14 03:10:40 +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 07293da97e eliminate InvalidateLabel and LabelIDList from MMI and replace 
them with a counter.

llvm-svn: 98462
 2010-03-14 02:24:55 +00:00
Chris Lattner ee95d4c61c use Label->isDefined() instead of isLabelDeleted() now that we 
consistently use MCSymbol and only call this predicate after
they should have been emitted.

llvm-svn: 98461

Chris Lattner f7aa541107 fix some pointless layering violations. 
llvm-svn: 98460
 2010-03-14 01:56:06 +00:00
Chris Lattner 34adc8d225 change EH related stuff (other than EH_LABEL) to use MCSymbol 
instead of label ID's.  This cleans up and regularizes a bunch 
of code and makes way for future progress.

Unfortunately, this pointed out to me that JITDwarfEmitter.cpp
is largely copy and paste from DwarfException/MachineModuleInfo
and other places.  This is very sad and disturbing. :(

One major change here is that TidyLandingPads moved from being
called in DwarfException::BeginFunction to being called in
DwarfException::EndFunction.  There should not be any 
functionality change from doing this, but I'm not an EH expert.

David Chisnall 2bfc50bf68 Fixed copy-and-paste error causing categories to contain the protocols declared on the class, not the protocols declared on the category.

Benjamin Kramer f156b9d55d Revert 98439. There is a bad race condition in sys::Path::makeUnique on win32.

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.
