Steve Naroff c6edcbdb5d Fix ASTContext::typesAreCompatible to allow for int/enum compatibility (C99 6.7.2.2p4).
Fix Sema::MergeFunctionDecl to allow for function type compatibility (by using the predicate on ASTContext). Function types don't have to be identical to be compatible...

Chris Lattner a30be59fa2 Fix a nasty corner case that Neil noticed in PR1900, where we would
incorrectly apply the multiple include optimization to files with

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.

Steve Naroff b74406ba98 Fixe bogus error for variable argument methods. Sema::ObjcGetTypeForMethodDefinition() wasn't preserving the isVariadic boolean. Another fix is to avoid synthsizing the function decl entirely, however this is a separate issue that I don't want to deal with now. Also added a FIXME to Sema::CheckFunctionCall(), which is currently emitting a bogus warning.
llvm-svn: 45146
2007-12-18 03:41:15 +00:00
Steve Naroff 1d2538cb4d Improve how we find private method decls. This involved:
- Changed Sema::ObjcActOnStartOfMethodDef() to register the methods with the global pools.
- Changed Sema::ActOnInstanceMessage() to look in global pools (should be much less error prone).
- Added a test case to message.m (for lookup that was broken).

Misc changes while I was investigating this...

- Changed Sema::ActOnAtEnd() to call AddFactoryMethodToGlobalPool (this looked like a cut/paste error).
- Added a comment and tweaked another where I was using the first person.

2007-12-17 21:03:50 +00:00
Ted Kremenek 3fbeaea7ee Modified format-string checking to not emit a warning when all of the
following hold:

(1) A vprintf-like function is called that takes the argument list via a
    via_list argument.

(2) The format string is a non-literal that is the parameter value of
    the enclosing function, e.g:
    
    void logmessage(const char *fmt,...) { 
      va_list ap;
      va_start(ap,fmt);
      fprintf(fmt,ap);  // Do not emit a warning.
    }
    
In the future this special case will be enhanced to consult the "format"
attribute attached to a function declaration instead of just allowing a blank
check for all function parameters to be used as format strings to vprintf-like
functions. This will happen when more support for attributes becomes
available.

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.

For example, for the test case "Sema/stmt_exprs.c", instead of the files
"Output/stmt_exprs.c.out" and "Output/stmt_exprs.c.out.script" being created, the
files "Output/Sema/stmt_exprs.c.out" and "Output/Sema/stmt_exprs.c.out.script" are
created. This prevents any collisions from different test directories that have the
same file name for a test case, and also makes it clear where the test case was
drawn from.

Steve Naroff cac26f4f5f This is the last 5% of the solution to teaching Sema::ActOnInstanceMessage() about private methods (r43989).
While the diff is large, the idea is very simple. When we parse method definitions (in an @implementation), we need to add them incrementally (rather than wait until the @end).

Other details...

- Renamed Sema::ActOnAddMethodsToObjcDecl() to Sema::ActOnAtEnd(). The methods are now optional arguments.
- Removed Parser::AllImplMethods (a nice cleanup).
- Added location info to ObjcImplementationDecl (since we will need it very soon:-)
- Modified message.m test to no longer allow the bogus diagnostic.

This commit is only 95% of the bug fix. The last piece to this puzzle is to add the method decls to the implementation incrementally (as we encounter them). At the moment, the methods aren't added until we see an @end (which is too late).

I will complete this later...

Ted Kremenek 5d18ce750a Added to test case for "self-comparison check" uses of relation operators: x < x and x > x
should emit warnings.

Ted Kremenek e451eae8d7 For non-floating point types, added check for expressions of the form
"x == x" and "x != x".  We emit a warning for these since they always evaluate
to a constant value and often indicate a logical error.

Added test case for this check.

Ted Kremenek d4ecc6da67 For checking for floating point comparison using == or !=, we now suppress
errors for cases such as "x == x".

Added test case to test this feature.

Chris Lattner 5c5808a9a3 improve error recovery handling broken 'then' or 'else' stmts in
if statements.  This implements Sema/if-empty-body.c:f3, silencing
a bogus secondary warning.  It also improve the location info for
the nullstmts created for recovery purposes.
