Bruno Cardoso Lopes 1f927ccaa2 Support x86 AVX 256-bit instructions built-ins. Right now support all of them, but 
as soon as we properly codegen the simple vector operations, remove the
unnecessary built-ins/intrinsics from clang and llvm. Also add tests for the new
built-ins

Tom Care 44081fbc6c Changed GRExprEngine to pass down a reference to itself when checkers are doing postanalysis. This allows the checker to gather information about the state of the engine when it has finished. 
- Exposed the worklist and BlockAborted flag in GRCoreEngine
- Changed postanalysis checkers to use the new infrastructure

are unknown.

Greg Clayton b0b9fe610a Added support for objective C built-in types: id, Class, and SEL. This 
involved watching for the objective C built-in types in DWARF and making sure
when we convert the DWARF types into clang types that we use the appropriate
ASTContext types.

Added a way to find and dump types in lldb (something equivalent to gdb's 
"ptype" command):

    image lookup --type <TYPENAME>

This only works for looking up types by name and won't work with variables.
It also currently dumps out verbose internal information. I will modify it
to dump more appropriate user level info in my next submission.

Hookup up the "FindTypes()" functions in the SymbolFile and SymbolVendor so
we can lookup types by name in one or more images.

Fixed "image lookup --address <ADDRESS>" to be able to correctly show all
symbol context information, but it will only show this extra information when
the new "--verbose" flag is used.

Updated to latest LLVM to get a few needed fixes.

Sean Callanan 4cf04d209b Set a CodeGenOption in Clang to inhibit insertion 
of profiling code into expressions.

Modified IRForTarget to emit array and record
member accesses correctly.  (Reading and writing
both work.)

Ted Kremenek 4a2b237967 Add -cc1 option '-unoptimized-cfg' to toggle using a CFG (for static analysis) that doesn't prune CFG edges. 
llvm-svn: 110087
 2010-08-03 00:09:51 +00:00
Dan Gohman 7cac95778f Make SCEVUnknown a CallbackVH, so that it can be notified directly 
of Value deletions and RAUWs, instead of relying on ScalarEvolution's
Scalars map being notified, as that's complicated at best, and
insufficient in general.

This means SCEVUnknown needs a non-trivial destructor, so introduce
a mechanism to allow ScalarEvolution to locate all the SCEVUnknowns.

llvm-svn: 110086
 2010-08-02 23:49:30 +00:00
Ted Kremenek dc03bd0894 Add 'AnalysisContext::getUnoptimizedCFG()' to allow clients to get access to the original 
CFG without any edges pruned out because of trivially solvable conditions (e.g., 'if (0)').

llvm-svn: 110085

John McCall 4a33fa95c0 Labels (and case statement) don't create independent scope parents for the 
purposes of the jump checker.  Also extend Ted's iteration fix to labels.

Fixes PR7789.

Oscar Fuentes e53004b188 explicit_map_components_to_libraries now does not complain when there 
is a dependence on an LLVM target that is not included on the build.

When LLVM_TARGETS_TO_BUILD didn't include all the targets, the
function emitted an error like

"Library LLVMArmParser not found in list of llvm libraries."
