Argyrios Kyrtzidis f4ebe9ea4f Handle unnamed bitfields when parsing C++ classes.
llvm-svn: 52855
2008-06-28 08:10:48 +00:00
Argyrios Kyrtzidis 7bbb20e338 Add parsing support for C++ classes.
Note that Parser::ParseCXXMemberSpecification is temporarily disabled until the Sema support is in place.
Once ParseCXXMemberSpecification is enabled, the Parser/cxx-class.cpp test will pass.

Chris Lattner 091f698d29 "this patch adds code generation hooks for Objective-C constant strings. It also modifies Sema so that Objective-C constant strings are treated as untyped objects if the interface for the constant string class can not be found. This is consistent with Apple GCC. I thought it was consistent with GNU GCC, since this was causing failures when trying to compile GNUstep with (GNU) GCC, but it appears that this is not the case when attempting to produce a simple test case to demonstrate it. Possibly there is a way of making the error go away, but I haven't found out what it is yet."

Eli Friedman 2460b0c941 Fix the scope of K&R-style argument declarations so that they don't
extend beyond the end of the function.

I'm not completely sure this is the right way to fix this bug, so 
someone familiar with the parser should double-check.

Nate Begeman f322eabbce Extend vector member references to include {.hi, .lo, .e, .o} which return a
vector of the same element type and half the width, with the high, low, even,
and odd elements respectively.

Allow member references to member references, so that .hi.hi gives you the high
quarter of a vector.  This is fairly convenient syntax for some insert/extract
operations.

Remove some unnecessary methods/types in the ExtVectorElementExpr class.

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 3e4683262e implement simple support for arbitrary token lookahead. Change the
objc @try parser to use it, fixing a FIXME.  Update the 
objc-try-catch-1.m file to pass now that we get more reasonable 
errors.

Chris Lattner 855d024a83 Remove the first layer of support for "portability" warnings. This is
theoretically useful, but not useful in practice.  It adds a bunch of 
complexity, and not much value.  It's best to nuke it.  One big advantage
is that it means the target interfaces will soon lose their SLoc arguments
and target queries can never emit diagnostics anymore (yay).  Removing this
also simplifies some of the core preprocessor which should make it slightly
faster.

Ted, I didn't simplify TripleProcessor, which can now have at most one
triple, and can probably just be removed.  Please poke at it when you have
time.

Chris Lattner 7b8134f5c6 Fix PR1999, by emitting a hard error only if an argument declarator is completely

Chris Lattner 9bad62c72a Merge all the 'assignment' diagnostic code into one routine, decloning
it from several places.  This merges the diagnostics, making them more
uniform and fewer in number. This also simplifies and cleans up the code.

Some highlights:
1. This removes a bunch of very-similar diagnostics.
2. This renames AssignmentCheckResult -> AssignConvertType
3. This merges PointerFromInt + IntFromPointer which were always treated the same.
4. This updates a bunch of test cases that have minor changes to the produced diagnostics.

Ted Kremenek b061554caa Implemented initial support for "-triple" option to the clang driver. This
replaces the functionality previously provided by just "-arch" (which is still
supported but has different semantics).

The new behavior is as follows:

(1) If the user does not specify -triple:

   (a) If no -arch options are specified, the target triple used is the host
   triple (in llvm/Config/config.h).
   
   (b) If one or more -arch's are specified (and no -triple), then there is
       one triple for each -arch, where the specified arch is substituted
       for the arch in the host triple.  Example:
          host triple = i686-apple-darwin9
          command: clang  -arch ppc -arch ppc64 ...
          triples used: ppc-apple-darwin9  ppc64-apple-darwin9
          
(2) The user does specify a -triple (only one allowed):

  (a) If no -arch options are specified, the triple specified by -triple
      is used.  E.g clang -triple i686-apple-darwin9
      
  (b) If one or more -arch options are specified, then the triple specified
      by -triple is used as the primary target, and the arch's specified
      by -arch are used to create secondary targets.  For example:
      
      clang -triple i686-apple-darwin9 -arch ppc -arch ppc64
      
      has the following targets:
         i686-apple-darwin9  (primary target)
         ppc-apple-darwin9
         ppc64-apple-darwin9


Other changes related to the changes to the driver:

- TargetInfoImpl now includes the triple string.

- TargetInfo::getTargetTriple returns the triple for its primary target.

- test case test/Parser/portability.c has been updated because "-arch linux" is
  no longer valid ("linux" is an OS, not an arch); instead we use a bogus
  architecture "bogusW16W16" where WCharWidth=16 and WCharAlign=16.
