Chris Lattner 3adb17d44f fix a bug I noticed by inspection, correcting two reject-valid bugs.

Chris Lattner a36ec4243b fix PR6811 by not parsing 'super' as a magic expression in
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.

Douglas Gregor 3baad0d4f7 Rename CodeModificationHint to FixItHint, since we've been using the
term "fix-it" everywhere and even *I* get tired of long names
sometimes. No functionality change.

Douglas Gregor 269f0b1b69 Merge the ASTVector and ASTOwningVector templates, since they offered
redundant functionality. The result (ASTOwningVector) lives in
clang/Parse/Ownership.h and is used by both the parser and semantic
analysis. No intended functionality change.

Douglas Gregor 8aa6bf5b8e Fix <rdar://problem/6724396>, where we were silently dropping
GNU-style array designators, causing us to emit broken initializers.

Sebastian Redl 726a0d9524 Put the invalid flag of OwningResult into the Action pointer.
This shrinks OwningResult by one pointer. Since it is no longer larger than OwningPtr, merge the two.
This leads to simpler client code and speeds up my benchmark by 2.7%.
For some reason, this exposes a previously hidden bug, causing a regression in SemaCXX/condition.cpp.

Douglas Gregor d14247a9e5 Implement and test aggregate initialization in C++. Major changes:
- Support initialization of reference members; complain if any
  reference members are left uninitialized.
  - Use C++ copy-initialization for initializing each element (falls
  back to constraint checking in C)
  - Make sure we diagnose when one tries to provide an initializer
  list for a non-aggregate.
  - Don't complain about empty initializers in C++ (they are permitted)
  - Unrelated but necessary: don't bother trying to convert the
  decl-specifier-seq to a type when we're dealing with a C++
  constructor, destructor, or conversion operator; it results in
  spurious warnings.

Chris Lattner 7368d581c1 Split the single monolithic DiagnosticKinds.def file into one
.def file for each library.  This means that adding a diagnostic
to sema doesn't require all the other libraries to be rebuilt.

Douglas Gregor e4a0bb7a20 Initial implementation of semantic analysis and ASTs for C99
designated initializers. This implementation should cover all of the
constraints in C99 6.7.8, including long, complex designations and
computing the size of incomplete array types initialized with a
designated initializer. Please see the new test-case and holler if you
find cases where this doesn't work.

There are still some wrinkles with GNU's anonymous structs and
anonymous unions (it isn't clear how these should work; we'll just
follow GCC's lead) and with designated initializers for the members of a
union. I'll tackle those very soon.

CodeGen is still nonexistent, and there's some leftover code in the
parser's representation of designators that I'll also need to clean up.

Steve Naroff 9e4ac111f0 Fix <rdar://problem/6150376> [sema] crash on invalid message send.
The core fix in Sema::ActOnClassMessage(). All the other changes have to do with passing down the SourceLocation for the receiver (to properly position the cursor when producing an error diagnostic).

Chris Lattner 8cc7be369c Fix PR3001: if we have an error parsing an initializer, make sure to remove
the designator corresponding to it, otherwise Sema and later parsing will
get confused.

Chris Lattner 248388e313 pass designators into sema. This completes parser-level designator
support as far as I know.

Chris Lattner 9a53fdc23e implement some more FIXMEs, by rejecting more bogus stuff in
objc mode.

2008-10-26 23:29:41 +00:00
Chris Lattner 46dcba6d2d add some simple designator testcases. Reject things like this:
struct foo Y[10] = {
  [4] .arr [2] 4  // expected-error {{expected '=' or another designator}}
};

because the "missing equals" extension only is valid if there 
is exactly one array designator.

Chris Lattner f3e58e2ebc This patch continues parser-level implementation of designators:
1. It introduces new parser level abstractions for designators
   that are used to communicate between parser and sema.
2. This fixes a FIXME where "identifier ':'" was considered to be
   a designator even if it wasn't the first in a designator list.
3. In the "identifier ':'" case, it actually builds the designator
   representation.

Chris Lattner 14cd1ee95f Two improvements to initializer parsing:
1. If we hit a semantic error, try harder to recover to emit
   diagnostics for later initializer errors (PR2241).
2. Don't leak parsed initializers on an error.

Chris Lattner 7a51313d8a Make a major restructuring of the clang tree: introduce a top-level
lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.
