John McCall 68cc3350a8 Fix a -Wuninitialized warning; it's actually a false positive, 
but it's not reasonable for the diagnostic to figure that out.
Pointed out by Benjamin Kramer.

Also clarify the logic here.

John McCall 8377967543 Warn about code that uses variables and functions with internal linkage 
without defining them.  This should be an error, but I'm paranoid about
"uses" that end up not actually requiring a definition.  I'll revisit later.

Also, teach IR generation to not set internal linkage on variable
declarations, just for safety's sake.  Doing so produces an invalid module
if the variable is not ultimately defined.

Also, fix several places in the test suite where we were using internal
functions without definitions.

Jim Ingham 85e8b81492 - Changed all the places where CommandObjectReturn was exporting a StreamString to just exporting 
a Stream, and then added GetOutputData & GetErrorData to get the accumulated data.
- Added a StreamTee that will tee output to two provided lldb::StreamSP's.
- Made the CommandObjectReturn use this so you can Tee the results immediately to
the debuggers output file, as well as saving up the results to return when the command
is done executing.
- HandleCommands now uses this so that if you have a set of commands that continue the target
you will see the commands come out as they are processed.
- The Driver now uses this to output the command results as you go, which makes the interface
more reactive seeming.

Argyrios Kyrtzidis 21f347e729 [analyzer] Fix crash when analyzing C++ code. 
llvm-svn: 126013

Ted Kremenek fda3687515 Add 'StoreRef' smart pointer to allow more fine-grain memory lifetime control of Store objects. 
This yields a minor memory reduction (for larger functions) on Sqlite at the cost of slightly
higher memory usage on some functions because of the increased size of GRState (which can be optimized).

I expect the real memory savings from this enhancement will come when we aggressively
canabilize more of the ExplodedGraph.

Ted Kremenek f66e5b695f Add ImmutableMap methods 'manualRetain()', 'manualRelease()', and 'getRootWithoutRetain()' to help more aggressively reclaim memory in the static analyzer.

Johnny Chen ce0dec7597 Make the helper method ReadCoreReg(uint32_t reg, bool *success) more generic 
which now handles R0-R12, SP, LR, as well as PC.  And refactored a lot of
calls to ReadRegisterUnsigned() to now funnel through ReadCoreReg(), instead.

Douglas Gregor 3a69eafa88 When code-completing a case statement for a switch on a value of

provide completions for any other expressions. Fixes <rdar://problem/7283668>.

Chris Lattner 7e5d8aa6f9 Now that -loop-idiom uses TargetLibraryInfo properly, it doesn't 
need to be pulled out of the pass manager when the user specifies 
-fno-builtin.  It can intelligently determine which libcalls to
optimize based on what is enabled in TargetLibraryInfo.  This 
allows -fno-builtin-foo to work someday.

Jakob Stoklund Olesen 4376d67b6f Use VirtRegMap's Virt2SplitMap to keep track of the original live range before splitting.

Douglas Gregor af2a6ae429 Selector::getIdentifierInfoForSlot() can return NULL values, a fact 
that was ignored in a few places (most notably, code
completion). Introduce Selector::getNameForSlot() for the common case
where we only care about the name. Audit all uses of
getIdentifierInfoForSlot(), switching many over to getNameForSlot(),
fixing a few crashers.

Fixed <rdar://problem/8939352>, a code-completion crasher.
