Douglas Gregor af82e3510b Introduce a new lexer function to compute the "preamble" of a file, 
which is the part of the file that contains all of the initial
comments, includes, and preprocessor directives that occur before any
of the actual code. Added a new -print-preamble cc1 action that is
only used for testing.

Ted Kremenek f03e6d85a1 Add 'ConversionSpecifier' root class in 'analyze_format_string' namespace and 
derived 'PrintfConversionSpecifier' from this class.  We will do the same for
'ScanfConversionSpecifier'.

Ted Kremenek ab0fe8a48d Rename analyze_printf::ConversionSpecifier::IntAsCharArg to 'cArg' to match

ConversionSpecifiers for both scanf and printf.

Chris Lattner b7a95cf165 delete a loop that just generates dead code. In an example 
like this:

void *test(long N) {
  return new int[N][42][42];
}

the loop generates two dead mul instructions:

  %tmp = load i64* %N.addr                        ; <i64> [#uses=2]
  %0 = mul i64 %tmp, 7056                         ; <i64> [#uses=1]
  %1 = mul i64 %tmp, 42                           ; <i64> [#uses=1]
  %2 = mul i64 %1, 42                             ; <i64> [#uses=0]
  %call = call noalias i8* @_Znam(i64 %0)         ; <i8*> [#uses=1]

The scale of these multiplies is already handled by the typesize stuff.

Chris Lattner cb46bdc34f remove the special case for constant array sizes from 
EmitCXXNewAllocSize.  This code uses IRBuilder, which does
constant folding already.

Argyrios Kyrtzidis dde5790562 Hide FunctionTemplateDecl's specializations folding set as implementation detail and introduce 
FunctionTemplateDecl::findSpecialization.

Redeclarations of specializations will not cause the previous decl to be removed from the set,
the set will keep the canonical decl. findSpecialization will return the most recent redeclaration.

llvm-svn: 108834
 2010-07-20 13:59:58 +00:00
Argyrios Kyrtzidis c1624e9eda Whether the specialization should be added to template's folding set when read from PCH, 
is determined by a isCanonicalDecl check.

 2010-07-20 13:59:40 +00:00
Argyrios Kyrtzidis 47470f2f3f Hide the specializations folding sets of ClassTemplateDecl as an implementation detail (InsertPos 
leaks though) and add methods to its interface for adding/finding specializations.

Simplifies its users a bit and we no longer need to replace specializations in the folding set with
their redeclarations. We just return the most recent redeclarations.

As a bonus, it fixes http://llvm.org/PR7670.

Sebastian Redl 3d3f0b1039 Remove PCHReader::getStream(), it was unused. Inline PCHReader::getDelsCursor() into its sole caller and remove it. This reduces the attack surface of multiple PCH files towards code outside the PCH implementation.

Ted Kremenek 6cd694233d Don't warn when a '%%' or '%*d' (scanf) is used in a format string with positional arguments, since

Douglas Gregor aa21cc401b Introduce a new libclang API, clang_reparseTranslationUnit(), which

optimizations.

Daniel Dunbar e38764c66c Driver: Change the driver to take the path to the main executable, instead of 
taking it in pieces.
 - Fixes a problem where the Clang executable path was not initialized properly
   on Win32, because sys::Path::getBasename() doesn't do what I always think it
   does. Imagine that, a sys::Path interface that is confusing!
