2012-08-18PR41111, PR5925, PR13210: Teach tentative parsing to annotate identifiers andRichard Smith
nested names as id-expressions, using the annot_primary_expr annotation, where possible. This removes some redundant lookups, and also allows us to typo-correct within tentative parsing, and to carry on disambiguating past an identifier which we can determine will fail lookup as both a type and as a non-type, allowing us to disambiguate more declarations (and thus offer improved error recovery for such cases). This also introduces to the parser the notion of a tentatively-declared name, which is an identifier which we *might* have seen a declaration for in a tentative parse (but only if we end up disambiguating the tokens as a declaration). This is necessary to correctly disambiguate cases where a variable is used within its own initializer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162159 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

2012-07-30Improvements to vexing-parse warnings. Make the no-parameters case moreRichard Smith
accurate by asking the parser whether there was an ambiguity rather than trying to reverse-engineer it from the DeclSpec. Make the with-parameters case have better diagnostics by using semantic information to drive the warning, improving the diagnostics and adding a fixit. Patch by Nikola Smiljanic. Some minor changes by me to suppress diagnostics for declarations of the form 'T (*x)(...)', which seem to have a very high false positive rate, and to reduce indentation in 'warnAboutAmbiguousFunction'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160998 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-09Better parser recovery in Objective-C containers.Jordan Rose
Previously it was possible to get an infinite-loop-on-invalid with a namespace decl within @interface. Since 'namespace' is normally a safe place to retry top-level parsing, we just didn't consume the token. This adds a flag that tracks whether we have temporarily left Objective-C scope to parse a C-like declaration, and uses that to better recover from parse problems by stopping at possible method declarations and at @end. To fix the original problem, we do /not/ stop at 'namespace' when in an Objective-C @interface or @protocol context (but still do in @implementation). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159941 91177308-0d34-0410-b5e6-96231b3b80d8

very simple semantic analysis that just builds the AST; minor changes for lexer to pick up source locations I didn't think about before.

2012-07-04Drop the ASTContext.h include from Stmt.h and fix up transitive users.Benjamin Kramer
This required moving the ctors for IntegerLiteral and FloatingLiteral out of line which shouldn't change anything as they are usually called through Create methods that are already out of line. ASTContext::Deallocate has been a nop for a long time, drop it from ASTVector and make it independent from ASTContext.h Pass the StorageAllocator directly to AccessedEntity so it doesn't need to have a definition of ASTContext around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159718 91177308-0d34-0410-b5e6-96231b3b80d8
