Douglas Gregor 93269380e7 Register the __builtin_va_list_type node when we parse it, rather than
waiting until we think we need it: we didn't catch all of the places
where we actually needed it, and we probably wouldn't ever. Fixes a
C++ PCH crasher.

Douglas Gregor af25cfaae0 When providing a block literal as a code completion for a
function/method argument, include the parameter name and always
include parentheses (even for zero-parameter blocks). Otherwise, the
block literal placeholder '^' can look very weird.

Douglas Gregor 97c7571ef3 Introduce a new libclang function, clang_getCursorDisplayName(), which
produces a simple "display" name that captures the
arguments/parameters for a function, function template, class
template, or class template specialization.

llvm-svn: 115428
2010-10-02 22:49:11 +00:00
Douglas Gregor 4e3918c06b Teach clang_getCursorType() about base specifiers and other references
to types. 

Also, teach clang_getTypeDeclaration() about template specializations,
injected-class-names, and elaborated types.

Fixes <rdar://problem/8506460>.

Douglas Gregor 99a26afd49 Extend libclang with an API that determines, given a C++ virtual
member function or an Objective-C method, which other member
functions/methods it overrides.

Douglas Gregor 2fb99df2c3 When setting the globally-visible declarations for a particular
identifier, we may have a Sema object but no translation unit scope
(because parsing is finished). In this case, we still need to update
the IdResolver, which might still be used when writing a PCH
containing another PCH (without chaining). This bug manifested as a
failure with precompiled preambles.

Also, add a little environment-variable-sensitive logging for
libclang.

Ted Kremenek f93eb1b09e Since this test depends on default ivar synthesis, specify the target triple. This hopefully unbreaks the buildbot
on some archs.

2010-09-24 01:24:15 +00:00
Ted Kremenek 74a9f98522 Default synthesized ivars don't really have a location in the source. Using the location of the @implementation
is just confusing for clients that want to use SourceLocations for syntactic references.

Douglas Gregor 0ac41389a4 Synchronize globally-cached code completion results with the results
provided when the optimization is disabled. In particular, split
the completion context CCC_Other into two contexts: CCC_Other, which
means that it's an undisclosed context for which any other results are
unwelcome, and CCC_Recovery, which is used in recovery cases.

Since we're now using the completion context within the completion
results builder, make sure that it's always set to something.

Fixes <rdar://problem/8470644>.

in the @interface.

Ted Kremenek cba5849c0b For properties declared in a @protocol and redeclared in a class extension, use the class extension
as the lexical DeclContext for the @property declaration that gets auto-created for the @interface.

llvm-svn: 114693
2010-09-23 21:18:05 +00:00
Ted Kremenek 2f07563f47 Correctly register the class extension as the lexical DeclContext for ObjC methods declared with @property in class extensions.
This matches the behavior for setters.

Also pass the class extension to ProcessPropertyDecl as the lexical DeclContext, even when not redeclaring the @property.

This fixes the remaining issues in <rdar://problem/7410145>.

2010-09-21 20:52:59 +00:00
Ted Kremenek e3a7d1ba40 For ObjCPropertyDecls in class extensions, use the class extension as the lexical DeclContext for newly created
ObjCMethodDecls.  Further, use the location of the new property declaration as the location of new ObjCMethodDecls
(if they didn't previously exist).

This fixes more of the issues reported in <rdar://problem/7410145>.

Douglas Gregor 7466127a4b When providing code completions for an argument in an Objective-C
message send, e.g.,

  [[NSString alloc] initWithCString:<CC>

look up all of the possible methods and determine the preferred type
for the argument expression based on the type of the corresponding
parameter.

Douglas Gregor 5fb901deee Code completion has no reason to prefer values over types, especially
at the statement level or in Objective-C message receivers. Therefore,
just give types and declarations the same basic priority, and adjust
from there.

Douglas Gregor db5c09a8cd Get rid of the lame attempt to prioritize "void" functions at
statement context; it really isn't helpful in practice (remember
printf!) and we'll be doing other adjustments for statements very soon.

2010-09-20 21:25:19 +00:00
Douglas Gregor 9dcf58a546 Tweak priorities for some types and macros:
- In Objective-C, we prefer BOOL to bool for historic reasons;
  slightly penalize "bool".
  - Treat Nil macro as a NULL pointer constant.
  - Treat YES, NO, true, and false macros as constants.
  - Treat the bool macro as a type.

Douglas Gregor 8af2ff89f7 Introduce a simple, substitution-based compression scheme for USRs, so
that redundant types don't result in super-long USRs. Fixes

Douglas Gregor ec06c124f1 Improve recovery when the middle expression of a ternary operator is ill-formed
llvm-svn: 114231
2010-09-17 22:41:34 +00:00
Douglas Gregor 29d907de03 When we run into an error parsing or type-checking the left-hand side
of a binary expression, continue on and parse the right-hand side of
the binary expression anyway, but don't call the semantic actions to
type-check. Previously, we would see the error and then, effectively,
skip tokens until the end of the statement. 

The result should be more useful recovery, both in the normal case
(we'll actually see errors beyond the first one in a statement), but
it also helps code completion do a much better job, because we do
"real" code completion on the right-hand side of an invalid binary
expression rather than completing with the recovery completion. For
example, given

  x = p->y

if there is no variable named "x", we can still complete after the p->
as a member expression. Along the recovery path, we would have
completed after the "->" as if we were in an expression context, which
is mostly useless.

Douglas Gregor 1154e27b4f Don't add two code-completion results for the same selector; it
doesn't add any value. Instead, we'll just take the first method with
that selector that we find and create a completion for it.

Douglas Gregor bfcea8b5b1 Implement code completion for Objective-C class message sends that are
missing the opening bracket '[', e.g.,

  NSArray <CC>

at function scope. Previously, we would only give trivial completions
(const, volatile, etc.), because we're in a "declaration name"
scope. Now, we also provide completions for class methods of NSArray,
e.g.,

  alloc

Note that we already had support for this after the first argument,
e.g.,

  NSArray method:x <CC>

would get code completion for class methods of NSArray whose selector
starts with "method:". This was already present because we recover
as if NSArray method:x were a class message send missing the opening
bracket (which was committed in r114057).

Douglas Gregor 3e972009fb Handle bracket insertion for Objective-C class messages in a very
narrow, almost useless case where we're inside a parenthesized
expression, e.g.,

  (NSArray alloc])

The solution to the general case still eludes me.

2010-09-15 23:19:31 +00:00
Douglas Gregor ed0b69dc81 Improve code completion for Objective-C message sends when the opening
'[' is missing. Prior commits improving recovery also improved code
completion beyond the first selector, e.g., at or after the "to" in

  calculator add:x to:y

but not after "calculator". We now provide the same completions for

  calculator <CC>

that we would for

  [calculator <CC>

if "calculator" is an expression whose type is something that can
receive Objective-C messages.

This code completion works for instance and super message sends, but not
class message sends.

llvm-svn: 113976
2010-09-15 16:23:04 +00:00
Douglas Gregor 5e35d59188 Introduce a new code-completion context for a parenthesized
expression, e.g., after the '(' that could also be a type cast. Here,
we provide types as code-completion results in C/Objective-C (C++
already had them), although we wouldn't in a normal expression context.

llvm-svn: 113904
2010-09-14 23:59:36 +00:00
Douglas Gregor 16a2bdd6b0 Introduce a new kind of cursor into libclang, which covers a reference
to an "overloaded" set of declarations. This cursor kind works for
unresolved references to functions/templates (e.g., a call within a
template), using declarations, and Objective-C class and protocol
forward declarations.

llvm-svn: 113805
2010-09-13 22:52:57 +00:00
Douglas Gregor 250ab1dc0e The two libclang crash-recovery tests that involve precompiled
preambles end up leaving the precompiled preambles around. This is by
design, since we do minimal cleanup during crash recovery. However,
it's unfortunate for testing, so introduce a hook that allows these
two tests to put the precompiled preamble somewhere where we can
delete them after testing.

llvm-svn: 113698

Douglas Gregor f3af311382 Teach libclang to walk the base and member initializers of a
