2013-05-03Move parsing of identifiers in MS-style inline assembly intoJohn McCall
the actual parser and support arbitrary id-expressions. We're actually basically set up to do arbitrary expressions here if we wanted to. Assembly operands permit things like A::x to be written regardless of language mode, which forces us to embellish the evaluation context logic somewhat. The logic here under template instantiation is incorrect; we need to preserve the fact that an expression was unevaluated. Of course, template instantiation in general is fishy here because we have no way of delaying semantic analysis in the MC parser. It's all just fishy. I've also fixed the serialization of MS asm statements. This commit depends on an LLVM commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180976 91177308-0d34-0410-b5e6-96231b3b80d8

This patch implements parsing ‘#pragma clang __debug’ as a first step for implementing captured statements.

2012-09-20If the range in a for range statement doesn't have a viable begin/end function,Richard Smith
but can be dereferenced to form an expression which does have viable begin/end functions, then typo-correct the range, even if something else goes wrong with the statement (such as inaccessible begin/end or the wrong type of loop variable). In order to ensure we recover correctly and produce any followup diagnostics in this case, redo semantic analysis on the for-range statement outside of the diagnostic trap, after issuing the typo-correction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164323 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-21Better diagnostics for range-based for loops with bad range types.Sam Panzer
The old error message stating that 'begin' was an undeclared identifier is replaced with a new message explaining that the error is in the range expression, along with which of the begin() and end() functions was problematic if relevant. Additionally, if the range was a pointer type or defines operator*, attempt to dereference the range, and offer a FixIt if the modified range works. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162248 91177308-0d34-0410-b5e6-96231b3b80d8
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
