Chandler Carruth c4d6fd5b03 Make sysroot only apply to baked in paths which start with a '/'.

Rafael Espindola 240028d11d Move the logic to decide with which symbol we produce a relocation (if any) to 
a central location. This also makes us a bit more compatible with gas.

Chris Lattner df8e17d80b implement support for the MO_DARWIN_STUB TargetOperand flag, 
and have isel apply to to call operands as required.  This allows
us to get $stub suffixes on label references on ppc/tiger with the
new instprinter, fixing two tests.  Only 2 to go.

Chris Lattner b7c67f6c17 with the picbase nonsense starting to be figured out, implement 
lowering support for MovePCtoLR[8].  Down to 4 failures again.

 2010-11-14 22:56:43 +00:00
Chris Lattner 7077efe894 move the pic base symbol stuff up to MachineFunction 
since it is trivial and will be shared between ppc and x86.
This substantially simplifies the X86 backend also.

Chris Lattner 239f9a35ed simplify getPICBaseSymbol a bit.

Chris Lattner 94f0c14cb0 reimplement ppc asmprinter "toc" handling to use a VariantKind 
on the operand, required for .o file writing and fixing 
the PowerPC/mult-alt-generic-powerpc64.ll failure with the new
instprinter.

Greg Clayton 83c5cd9dfd Just like functions can have a basename and a mangled/demangled name, variable 
can too. So now the lldb_private::Variable class has support for this.

Variables now have support for having a basename ("i"), and a mangled name 
("_ZN12_GLOBAL__N_11iE"), and a demangled name ("(anonymous namespace)::i").

Nowwhen searching for a variable by name, users might enter the fully qualified
name, or just the basename. So new test functions were added to the Variable 
and Mangled classes as:

	bool NameMatches (const ConstString &name);
	bool NameMatches (const RegularExpression &regex);

I also modified "ClangExpressionDeclMap::FindVariableInScope" to also search
for global variables that are not in the current file scope by first starting
with the current module, then moving on to all modules.

Fixed an issue in the DWARF parser that could cause a varaible to get parsed
more than once. Now, once we have parsed a VariableSP for a DIE, we cache
the result even if a variable wasn't made so we don't do any re-parsing. Some
DW_TAG_variable DIEs don't have locations, or are missing vital info that 
stops a debugger from being able to display anything for it, we parse a NULL
variable shared pointer for these DIEs so we don't keep trying to reparse it.

Chris Lattner 2f9f63af0b lower PPC::MFCRpseud when transforming to MC, avoiding calling 
the aborting printSpecial() method.  This gets us to 8 failures.

Chris Lattner cfb6287487 make the stubbed-out printer methods abort instead of 
printing nothing.  This gets us back up to 24 failures.

among others.  Down to 20 failures.

Chris Lattner c2ac86e261 Wire up symbol hi/lo printing. We don't print hi()/lo(), but this gets 
us further along.  Only 28 failures now.

llvm-svn: 119071
 2010-11-14 21:00:02 +00:00
Chris Lattner c5afd12557 even more simplifications. ARM MCInstLowering is now just 
a single function instead of a class.  It doesn't need the
complexity that X86 does.

 2010-11-14 20:11:21 +00:00
Chris Lattner 7a5c57ecf4 Implement support for printing register and immediate operands, 
add support for darwin vs aix syntax.  We now can print instructions
like this:

	add r3, r3, r4
	blr 

and (in aix mode):
	add 3, 3, 4
	blr

Chris Lattner 686a095d89 stub out PPCMCInstLowering, add a new option that uses it and the new 
instprinter when -enable-ppc-inst-printer is passed to llc.

 2010-11-14 19:12:57 +00:00
Chris Lattner 287766075f fix the autoconf script to detect "has asmprinter"ness of a target by 
looking for lib/Target/*AsmPrinter.cpp.  Fix llvm-config to handle targets
that don't have an explicit AsmPrinter library.

llvm-svn: 119057
 2010-11-14 19:10:47 +00:00
Chris Lattner 66031ed839 move all the target's asmprinters into the main target. The piece 
that should be split out is the InstPrinter (if a target is mc'ized).
This change makes all the targets be consistent.

llvm-svn: 119052
 2010-11-14 18:25:50 +00:00
Chris Lattner 9007c368c6 remove JIT support from the Alpha backend. The JIT will be moving to MC, 
and the Alpha backend isn't MCized yet.  Approved by Andrew.

Ted Kremenek 0526f52a49 Revert r119045. It was failing on Windows. 
llvm-svn: 119048
 2010-11-14 17:53:34 +00:00
Ted Kremenek ca817a3c0c "Fix" some unintentional fallout from converting 
the Stmt* visitation in CursorVisitor to be
data-recursive.

Since AnnotationTokensWorker explicitly calls
CursorVisitor::VisitChildren(), it essentially
transforms the data-recursive algorithm in
CursorVisitor back into a non-data recursive one.
This is particularly bad because the data-recursive
algorithm uses more stack space per stack frame,
which can cause us to blow the stack in some cases.

"Fix" this by making the stack that AnnotationTokensWorker
runs in really huge.  The real fix is to modify
AnnotationTokensWorker not to do the explicit
recursive call.

Ted Kremenek 96b329c428 Clean up initialization of LangOptions object by splitting part of it into a parent class 
'LangOptionsBase' that default initializes all flags to 0.  Now the ctor of LangOptions
only initializes the flags that might be non-zero (significantly simplifying things).

This also appeases Valgrind on Mac OS X, which no longer reports that one of the flags
may be uninitialized.
