* fix PR6811 by not parsing 'super' as a magic expression inChris Lattner2010-04-113-27/+45
| | | | | | | | | | | | | LookupInObjCMethod. Doing so allows all sorts of invalid code to slip through to codegen. This patch does not change the AST representation of super, though that would now be a natural thing to do since it can only be in the receiver position and in the base of a ObjCPropertyRefExpr. There are still several ugly areas handling super in the parser, but this is definitely a step in the right direction. llvm-svn: 100959
* Diagnose misordered initializers in constructor templates immediately instead ofJohn McCall2010-04-102-5/+16

Don't crash in the parser when a constructor's initializers end in a comma and there's no body; the recovery here is still terrible, but anything's better than a crash. llvm-svn: 100922

* Fix an amusing typo that completely the re-introduction of parametersDouglas Gregor2010-03-021-1/+1
| | | | | | | | | | | for the purposes of parsing default arguments. In effect, we would re-introduce the parameter with a default argument N times (where N is the number of parameters preceding the parameter with a default argument). This showed up when a defaulted parameter of a member function of a local class shadowed a parameter of the enclosing function. Fixes PR6383. llvm-svn: 97534

* When we're parsing template names as part of base-specifiers, we areDouglas Gregor2010-03-011-1/+1

* Keep an explicit stack of function and block scopes, each element ofDouglas Gregor2010-03-011-0/+1
| | | | | | | | | | | | | | | | | | | | which has the label map, switch statement stack, etc. Previously, we had a single set of maps in Sema (for the function) along with a stack of block scopes. However, this lead to funky behavior with nested functions, e.g., in the member functions of local classes. The explicit-stack approach is far cleaner, and we retain a 1-element cache so that we're not malloc/free'ing every time we enter a function. Fixes PR6382. Also, tweaked the unused-variable warning suppression logic to look at errors within a given Scope rather than within a given function. The prior code wasn't looking at the right number-of-errors count when dealing with blocks, since the block's count would be deallocated before we got to ActOnPopScope. This approach works with nested blocks/functions, and gives tighter error recovery. llvm-svn: 97518
* Robustify instantiation of templates when there are errors in theDouglas Gregor2010-03-011-4/+4
| | | | | | | | | template definition. Do this both by being more tolerant of errors in our asserts and by not dropping a variable declaration completely when its initializer is ill-formed. Fixes the crash-on-invalid in PR6375, but not the original issue. llvm-svn: 97463

* Fix an assertion-on-error during tentative constructor parsing byJohn McCall2010-02-266-75/+107
| | | | | | | | | | propagating error conditions out of the various annotate-me-a-snowflake routines. Generally (but not universally) removes redundant diagnostics as well as, you know, not crashing on bad code. On the other hand, I have just signed myself up to fix fiddly parser errors for the next week. Again. llvm-svn: 97221

| | | | | | | | | class types, dependent types, and namespaces. I had previously weakened this invariant while working on parsing pseudo-destructor expressions, but recent work in that area has made these changes unnecessary. llvm-svn: 97112

* ActOnPseudoDestructorExpr now performs all semantic analysis forDouglas Gregor2010-02-241-2/+6
| | | | | | | | | | | | | | | | pseudo-destructor expressions, and builds the CXXPseudoDestructorExpr node directly. Currently, this only affects pseudo-destructor expressions when they are parsed, but not after template instantiation. That's coming next... Improve parsing of pseudo-destructor-names. When parsing the nested-name-specifier and we hit the sequence of tokens X :: ~, query the actual module to determine whether X is a type-name (in which case the X :: is part of the pseudo-destructor-name but not the nested-name-specifier) or not (in which case the X :: is part of the nested-name-specifier). llvm-svn: 97058
* Rework parsing of pseudo-destructor expressions and explicitDouglas Gregor2010-02-242-20/+144
| | | | | | | | | | | | | | | | | | | | | | | | | | | | destructor calls, e.g., p->T::~T We now detect when the member access that we've parsed, e.g., p-> or x. may be a pseudo-destructor expression, either because the type of p or x is a scalar or because it is dependent (and, therefore, may become a scalar at template instantiation time). We then parse the pseudo-destructor grammar specifically: ::[opt] nested-name-specifier[opt] type-name :: ∼ type-name and hand those results to a new action, ActOnPseudoDestructorExpr, which will cope with both dependent member accesses of destructors and with pseudo-destructor expressions. This commit affects the parsing of pseudo-destructors, only; the semantic actions still go through the semantic actions for member access expressions. That will change soon. llvm-svn: 97045
