Chris Lattner 8811e12314 factor some labels, simplify some code. 
llvm-svn: 98429
 2010-03-13 07:40:56 +00:00
Chris Lattner 2c3f478c0b various cleanups. 
llvm-svn: 98426
 2010-03-13 07:26:18 +00:00
Chris Lattner b7aa9527ef reimplement the string pool used for inlined function 
entries to not thrash std::strings and MCSymbols.

llvm-svn: 98415
 2010-03-13 02:17:42 +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
Jeffrey Yasskin 35b4e4f641 Free DbgScopes in DwarfDebug::endFunction(). Also increased the const-ness of 
several fields to make it easier to figure out where bugs might be creeping in.

llvm-svn: 98358
 2010-03-12 17:45:06 +00:00
Devang Patel f5c2a6b371 There is no need to create specification DIE for definitions at DIFile level. 
llvm-svn: 98302
 2010-03-11 23:44:52 +00:00
Jeffrey Yasskin 0708de1f97 Avoid leaking CompileUnits in DwarfDebug.cpp. 
llvm-svn: 98268
 2010-03-11 18:29:55 +00:00
Chris Lattner a26fbe4d68 add missing filename! 
llvm-svn: 98125
 2010-03-10 02:29:31 +00:00
Chris Lattner b245dfb408 inline away a form of IsPCRelative, eliminating the 
dead IsPCRel argument.

llvm-svn: 98117
 2010-03-10 01:17:49 +00:00
Chris Lattner 7e998b7363 add some fixme's for MCizing. EH still has a few things that 
need to be MCized, but the last debug info thing are LEB and
cygwin specific (which the MC api doesn't support yet) and
one specific form of EmitReference which I'll tackle next.

llvm-svn: 98116
 2010-03-10 01:04:13 +00:00
Chris Lattner 566cae9086 eliminate EOL, adding all comments with the OutStreamer.AddComment 
method.  With this, comments should end up on the same lines as the .byte
directives (for example) and we now get no output with:

$ llc CodeGen/X86/2009-02-12-DebugInfoVLA.ll -o - -filetype=null -asm-verbose

woot.

llvm-svn: 98105
 2010-03-09 23:52:58 +00:00
Chris Lattner 3d72a678de eliminate a bunch of \n's that are being printed to O. Next up is to kill 
off "EOL".

llvm-svn: 98102
 2010-03-09 23:38:23 +00:00
Chris Lattner ba35a67062 reapply r98035: 
Now that setStartLabel takes an MCSymbol, we can de-ID'ize
beginScope and RecordSourceLine.

llvm-svn: 98047
 2010-03-09 04:54:43 +00:00
Chris Lattner 54a6876821 add some extra checks. I'm not sure why, but this does unbreak a 
failure remaining on mainline.

llvm-svn: 98046
 2010-03-09 04:48:35 +00:00
Eric Christopher 66194fbf86 Speculatively revert r98035. It appears to have caused a set of buildbot 
failures.

llvm-svn: 98039
 2010-03-09 02:36:31 +00:00
Chris Lattner 06c5e9060c Now that setStartLabel takes an MCSymbol, we can de-ID'ize 
beginScope and RecordSourceLine.

llvm-svn: 98035
 2010-03-09 02:08:02 +00:00
Chris Lattner e13c37232a change DbgScope to keep track of the start/end label as MCSymbol* 
now that the dependence on ID is removed from MMI.

llvm-svn: 98034
 2010-03-09 01:58:53 +00:00
Chris Lattner a552246b3d remove a useless optimization: now that label replacement never 
happens, the start/end of a scope can never be the same.

llvm-svn: 98032
 2010-03-09 01:52:43 +00:00
Chris Lattner c3b70f636f strength reduce MMI::MappedLabel to MMI::isLabelDeleted, 
and add a FIXME about how we are eventually going to zap this
lookup table once mc world domination is complete.

llvm-svn: 98031
 2010-03-09 01:51:43 +00:00
Chris Lattner 9e57c676dd mcstreamerize AsmPrinter::printLabel. 
llvm-svn: 98025
 2010-03-09 01:02:30 +00:00
Chris Lattner b14490d912 add a EmitSymbolValue convenience method to MCStreamer. 
llvm-svn: 98017
 2010-03-09 00:39:24 +00:00
Chris Lattner 085b65283c make InlineInfoLabels hold MCSymbol*'s, avoiding 
recomputation of the labels.

llvm-svn: 98016
 2010-03-09 00:31:02 +00:00
Chris Lattner 53d6d1e87d mc'ize the last use of PrintLabelName and eliminate PrintLabelName. 
llvm-svn: 98015
 2010-03-09 00:26:09 +00:00
Chris Lattner 4d728127fb now that the debug and eh emitters use a common .set counter, 
we can eliminate "flavor".

llvm-svn: 98011
 2010-03-09 00:00:15 +00:00
Chris Lattner 27a9732450 simplify EmitSectionOffset to always use .set if it is 
available, the only thing this affects is that we produce
.set in one case we didn't before, which shouldn't harm
anything.  Make EmitSectionOffset call EmitDifference
instead of duplicating it.

llvm-svn: 98005
 2010-03-08 23:23:25 +00:00
Chris Lattner 449a9ff14b Remove a version of EmitDifference.

llvm-svn: 97995
 2010-03-08 22:31:46 +00:00
Chris Lattner bc9210cb70 elimiante the DWLabel class, using MCSymbol instead. Start 
switching some stuff over to passing around MCSymbol* instead
of stem+ID.

llvm-svn: 97993
 2010-03-08 22:23:36 +00:00

Jim Grosbach bf6d35893f Add getFrameIndexReference() to TargetRegisterInfo, which allows targets to 
tell debug info which base register to use to reference a frame index on a
per-index basis. This is useful, for example, in the presence of dynamic
stack realignment when local variables are indexed via the stack pointer and
stack-based arguments via the frame pointer.

Devang Patel 92e8c655b2 There is no need to use FoldingSet to unique DIEs. 
DIEs are created from MDNode, which are already uniqued. And DwarfDebug already uses ValueMaps to find and use existing DIE for a given MDNode.
