Benjamin Kramer b11416d061 Add raw_ostream operators to NamedDecl for convenience. Switch over all users of getNameAsString on a stream.
The next step is to print the name directly into the stream, avoiding a temporary std::string copy.

Eric Christopher 8d0c621ca6 Consolidate most of the integer constant expression builtin requirement
checking into a single function and use that throughout. Remove some
now unnecessary diagnostics and update tests with now more accurate
diagnostics.

Chris Lattner 4ebae65d6a make our existing "switch on bool" warning work for C. Since
the result of comparisons are 'int' in C, it doesn't work to
test just the result type of the expression.

Douglas Gregor 24f27696db If a non-noreturn virtual member function is guaranteed not to return,
do *not* suggest that the function could be attribute 'noreturn';
overridden functions may end up returning.

Douglas Gregor 19175ffb67 Switch Sema::FindCompositePointerType() over to InitializationSequence.
This is the last of the uses of TryImplicitConversion outside of
overload resolution and InitializationSequence itself.

Douglas Gregor b33eed0ced Collapse the three separate initialization paths in
TryStaticImplicitCast (for references, class types, and everything
else, respectively) into a single invocation of
InitializationSequence.

One of the paths (for class types) was the only client of
Sema::TryInitializationByConstructor, which I have eliminated. This
also simplified the interface for much of the cast-checking logic,
eliminating yet more code.

I've kept the representation of C++ functional casts with <> 1
arguments the same, despite the fact that I hate it. That fix will
come soon. To satisfy my paranoia, I've bootstrapped + tested Clang
with these changes.

Douglas Gregor 5c8ffab9fb Switch the checking of implicit casts for static_cast, C-style, and
functional casts over to InitializationSequence, eliminating a caller
of Sema::TryImplicitConversion. We also get access and ambiguity
checking "for free".

More cleanups to come in this routine.

Douglas Gregor b8eaf2944b Audit uses of Sema::LookupSingleName for those lookups that are
intended for redeclarations, fixing those that need it. Fixes PR6831.

This uncovered an issue where the C++ type-specifier-seq parsing logic
would try to perform name lookup on an identifier after it already had
a type-specifier, which could also lead to spurious ambiguity errors
(as in PR6831, but with a different test case).

2010-04-15 23:40:53 +00:00
Douglas Gregor b2ccf010fb Feed proper source-location information into Sema::LookupSingleResult,

(template instantiation, ambiguity reporting, access
reporting). Noticed while working on PR6831.

Douglas Gregor c1cf814c8b Fix a few cases where enum constant handling was using
ASTContext::getTypeSize() rather than ASTContext::getIntWidth() for
the width of an integral type. The former includes padding for bools
(to the target's size) while the latter does not, so we woud end up
zero-extending bools to the target width when we shouldn't. Fixes a
crash-on-valid in the included test.

Douglas Gregor 064fdb2fe8 Always diagnose and complain about problems in
ResolveAddressOfOverloadedFunction when asked to complain. Previously,
we had some weird handshake where ResolveAddressOfOverloadedFunction
expected its caller to handle some of the diagnostics but not others,
and yet there was no way for the caller to know which case we were
in. Eliminate this madness, fixing <rdar://problem/7765884>.

2010-04-14 20:27:54 +00:00
Douglas Gregor 280e1ee0ae Teach typo correction about various language keywords. We can't
generally recover from typos in keywords (since we would effectively
have to mangle the token stream). However, there are still benefits to
typo-correcting with keywords:
  - We don't make stupid suggestions when the user typed something
  that is similar to a keyword. 
  - We can suggest the keyword in a diagnostic (did you mean
  "static_cast"?), even if we can't recover and therefore don't have
  a fix-it.

2010-04-14 20:04:41 +00:00
Douglas Gregor fd0e2e31be Return the corrected DeclarationName from Sema::CorrectTypo rather
than just a bool indicating that correction occurred. No actual
functionality change (it's still always used like a bool), but this
refactoring will be used to support typo correction to keywords.

Douglas Gregor 2bf2d3d016 When diagnosing suspicious precedence or assignments, move the fix-it
that adds parentheses from the main diagnostic down to a new
note. This way, when the fix-it represents a choice between two
options, each of the options is associted with a note. There is no
default option in such cases. For example:

/Users/dgregor/t.c:2:9: warning: & has lower precedence than ==; ==
will be
      evaluated first [-Wparentheses]
  if (x & y == 0) {
        ^~~~~~~~
/Users/dgregor/t.c:2:9: note: place parentheses around the &
expression to
      evaluate it first
  if (x & y == 0) {
        ^
      (    )
/Users/dgregor/t.c:2:9: note: place parentheses around the ==
expression to
      silence this warning
  if (x & y == 0) {
        ^
          (     )

Douglas Gregor 8aa4ebf0bc Implement typo correction for Objective-C message sends when the
receiver is a mis-typed class name. Previously, we would give a non-specific
typo-correction diagnostic from the expression-parsing code, but there
was no fix-it because it was too late to recover. Now, we give a nice
diagnostic

honk.m:6:4: error: unknown receiver 'Hnk'; did you mean 'Honk'?
  [Hnk method];
   ^~~
   Honk
honk.m:1:1: note: 'Honk' declared here
@interface Honk
^

which includes a fix-it.

We still need to recover better from mis-typing "super".

Douglas Gregor 38ae6ab6bc Refactor and simplify the computation of implicit conversion sequences
for reference binding. The code attempted to handle both the
computation of the ICS and the actual conversion, but the latter is an
anachronism: we now use InitializationSequence for that. 

Sema::CheckReferenceInit is now a static function TryReferenceInit
that's only use within overload resolution, and has been simplified
slightly. It still needs to be updated per C++ [over.ics.ref], by
eliminating more of the lvalue/rvalue checks.
