cf30755a41 Bug #:
Submitted by:
Reviewed by:
Refactored ParseNumericConstant using SkipDigits and friends. This
cleaned up the code and removed many "breaks". In the process, I found
several bugs that needed to be fixed (proof that this refactoring had
real value, not simply aesthetics). Also simplified error handling logic
and removed an unused error condition from Diagnostics.def.

8160ea2072 Bug #:
Submitted by:
Reviewed by:
More code to parse numeric constants. This checkin includes:
- Feedback from Chris.
- Support for parsing floating point constants.
- Moved the code to "Sema". Changed API in Action.
- More/better error diagnostics.

At this point, the parsing support should be largely complete. Next step
is to work on filling in sensible values (in IntegerLiteral/FloatLiteral).

38d31b47b0 Make Sema's use of the preprocessor explicit (rather than assume
the prerocessor will be available via ASTContext).
- Removed the public data member "PP" in ASTContext.
- Changed ASTContext's contructor to take TargetInfo/IdentifierTable explicitly.
- Implicitly create an ASTContext in Sema's constructor. This simplifies
the clients job (and makes ASTContext more private).
--As a side effect, added a "PrintStats" hook to Sema.

To support this level of encapsulation, ASTContext is always dynamically
allocated (by Sema). Previously, ASTContext was being allocated on the
stack. I don't believe this should be a performance issue (since ASTContext
is fairly course grain and tied to the lifetime of Sema currently).

df7855bb17 Batch search/replace snafu (inadvertantly changed IntegerConstant->StringLiteral).
clang still compiled/linked/ran properly...simply a confusing name regression.
From now on I'll make sure I run "cvs diff" before committing any changes!

9561a0b3e7 Add support for target-independent builtin functions (like __builtin_abs),
whose decl objects are lazily created the first time they are referenced.
Builtin functions are described by the clang/AST/Builtins.def file, which
makes it easy to add new ones.

This is missing two important pieces:
1. Support for the rest of the gcc builtins.
2. Support for target-specific builtins (e.g. __builtin_ia32_emms).

Just adding this builtins reduces the number of implicit function definitions
by 6, reducing the # diagnostics from 550 to 544 when parsing carbon.h.

I need to add all the i386-specific ones to eliminate several hundred more.
ugh.

17ed487947 parse identifier expressions properly. This allows us diagnose this:
typedef int X;

int A() {
  return X;
}

int B() {
  return Y;
}

as:

/Users/sabre/test.c:5:10: error: unexpected type name 'X': expected expression
return X;
       ^
/Users/sabre/test.c:9:10: error: use of undeclared 'Y' value
return Y;
       ^

33e8a55ed0 Parse and remember types enough that we can pretty print:
void foo(int X) {
  X = __alignof(int);
  X = sizeof(const int** restrict ** volatile*);
}

as:

x = __alignof(int)
x = sizeof(int const **restrict **volatile *)
