John McCall [Tue, 25 May 2010 04:30:21 +0000 (04:30 +0000)]
If a function definition has any sort of weak linkage, its static local
variables should have that linkage.  Otherwise, its static local
variables should have internal linkage.  To avoid computing this excessively,
set a function's linkage before we emit code for it.

Previously we were assigning weak linkage to the static variables of
static inline functions in C++, with predictably terrible results.  This
fixes that and also gives better linkage than 'weak' when merging is required.

Improve our handling of reference binding for subobjects of

  - When converting an object to a base class, it's only an lvalue
  cast when the original object was an lvalue and we aren't casting
  pointer-to-derived to pointer-to-base. Previously, we were
  misclassifying derived-to-base casts of class rvalues as lvalues,
  causing various oddities (including problems with reference binding
  not extending the lifetimes of some temporaries).

  - Teach the code for emitting a reference binding how to look
  through no-op casts and parentheses directly, since
  Expr::IgnoreParenNoOpCasts is just plain wrong for this. Also, make
  sure that we properly look through multiple levels of indirection
  from the temporary object, but destroy the actual temporary object;
  this fixes the reference-binding issue mentioned above.

  - Teach Objective-C message sends to bind the result as a temporary
    when needed. This is actually John's change, but it triggered the
    reference-binding problem above, so it's included here. Now John
    can actually test his return-slot improvements.

14 years agoImprove parser recovery when we encounter a dependent template name
Douglas Gregor [Fri, 21 May 2010 23:18:07 +0000 (23:18 +0000)]
Improve parser recovery when we encounter a dependent template name
that is missing the 'template' keyword, e.g.,

  t->getAs<T>()

where getAs is a member of an unknown specialization. C++ requires
that we treat "getAs" as a value, but that would fail to parse since T
is the name of a type. We would then fail at the '>', since a type
cannot be followed by a '>'.

This is a very common error for C++ programmers to make, especially
since GCC occasionally allows it when it shouldn't (as does Visual
C++). So, when we are in this case, we use tentative parsing to see if
the tokens starting at "<" can only be parsed as a template argument
list. If so, we produce a diagnostic with a fix-it that states that
the 'template' keyword is needed:

test/SemaTemplate/dependent-template-recover.cpp:5:8: error: 'template' keyword
      is required to treat 'getAs' as a dependent template name
    t->getAs<T>();
       ^
       template

This is just a start of this patch; I'd like to apply the same
approach to everywhere that a template-id with dependent template name
can be parsed.
