2012-08-17darwin/driver: Support using SDKROOT to define the default for -isysroot.Daniel Dunbar
- The SDKROOT environment variable is the de facto way to set the default SDK for a number of tools, join forces with them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162116 91177308-0d34-0410-b5e6-96231b3b80d8

GCC documents these as unsigned, but defines them as signed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162106 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-17[ms-inline asm] Instantiate the MCStreamer as a NullStream. We're parsingChad Rosier

2012-08-17Warn about self-initialization of references.Hans Wennborg
Initializing a reference with itself, e.g. "int &a = a;" seems like a very bad idea. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162093 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-17When we need the complete set of visible declarations from aDouglas Gregor
declaration context, check whether the primary context---not the current context---has any external visible declarations. Fixes PR13616. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162083 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-17Don't do jump-scope checking when code completion is enabled. It'sDouglas Gregor
both a waste of time, and prone to crash due to the use of the error-recovery path in parser. Fixes <rdar://problem/12103608>, which has been driving me nuts. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162081 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-17Fix undefined behavior in debug info emission: operator* on WeakVH returns aRichard Smith
reference, so &* on an empty WeakVH binds a reference to a dereferenced null pointer. So don't do that; we have a perfectly good implicit conversion to Value*. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162079 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-17[analyzer] Add an internal reference document describing IPA and CallEvent.Jordan Rose
This attempts to be a higher-level description of our inlining heuristics and decision trees than the source, where the work is spread out between ExprEngine (mostly in ExprEngineCallAndReturn.cpp) and CallEvent, with a few other classes participating as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162073 91177308-0d34-0410-b5e6-96231b3b80d8

elaborated type specifier in template instantiation: such a specifier is always valid because it must be specified within the definition of the type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162068 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-17Add support for "type safety" attributes that allow checking that 'void *'Dmitri Gribenko
function arguments and arguments for variadic functions are of a particular type which is determined by some other argument to the same function call. Usecases include: * MPI library implementations, where these attributes enable checking that buffer type matches the passed MPI_Datatype; * for HDF5 library there is a similar usecase as MPI; * checking types of variadic functions' arguments for functions like fcntl() and ioctl(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162067 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-16[ms-inline asm] Add a helper function, isMSAsmKeyword().Chad Rosier
These require special handling, which we don't currently handle. This is being put in place to ensure we don't do invalid symbol table lookups or try to parse invalid assembly.

2012-08-16Remove #if 0 that has been around for a long time.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162030 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-16Remove "range_iterator" from PathDiagnosticPiece and just use ↵Ted Kremenek
ArrayRef<SourceRange> for ranges. This removes conceptual clutter, and can allow us to easy migrate to C++11 style for-range loops if we ever move to using C++11 in Clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162029 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-16Allow multiple PathDiagnosticConsumers to be used with a BugReporter at the ↵Ted Kremenek
same time. This fixes several issues: - removes egregious hack where PlistDiagnosticConsumer would forward to HTMLDiagnosticConsumer, but diagnostics wouldn't be generated consistently in the same way if PlistDiagnosticConsumer was used by itself. - emitting diagnostics to the terminal (using clang's diagnostic machinery) is no longer a special case, just another PathDiagnosticConsumer. This also magically resolved some duplicate warnings, as we now use PathDiagnosticConsumer's diagnostic pruning, which has scope for the entire translation unit, not just the scope of a BugReporter (which is limited to a particular ExprEngine). As an interesting side-effect, diagnostics emitted to the terminal also have their trailing "." stripped, just like with diagnostics emitted to plists and HTML. This required some tests to be updated, but now the tests have higher fidelity with what users will see. There are some inefficiencies in this patch. We currently generate the report graph (from the ExplodedGraph) once per PathDiagnosticConsumer, which is a bit wasteful, but that could be pulled up higher in the logic stack. There is some intended duplication, however, as we now generate different PathDiagnostics (for the same issue) for different PathDiagnosticConsumers. This is necessary to produce the diagnostics that a particular consumer expects. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162028 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-16[ms-inline asm] Start tracking which tokens are registers and which areChad Rosier
variables, function or label references. The former is a potential clobber. The latter is either an input or an output. Unfortunately, it's difficult to test this patch at the moment, but the added test case will eventually do so. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162026 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-16Store SourceManager pointer on PrintingPolicy in the case where we're dumping,Richard Smith
and remove ASTContext reference (which was frequently bound to a dereferenced null pointer) from the recursive lump of printPretty functions. In so doing, fix (at least) one case where we intended to use the 'dump' mode, but that failed because a null ASTContext reference had been passed in. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162011 91177308-0d34-0410-b5e6-96231b3b80d8
