Chris Lattner 3474c202ab refactor scalar conversions out into CGExprScalar.cpp

Chris Lattner 1a76a3c970 Break the assumption that any sort of scope (e.g. a loop scope) can 
hold declarations.  Instead, introduce a new "DeclScope" scope type that
holds them explicitly.  For now, all scopes have this bit, but in the 
future we can use them to fix some issues Neil noticed.

 2007-08-26 03:51:12 +00:00
Chris Lattner 1c20a170c0 add a new ImaginaryLiteral AST node that is used to 
represent imaginary literals:

float _Complex A;
void foo() {
  A = 1.0iF;
}

generates:

  (BinaryOperator 0x2305ec0 '_Complex float' '='
    (DeclRefExpr 0x2305e60 '_Complex float' Decl='A' 0x2305cf0)
    (ImaginaryLiteral 0x2305f40 '_Complex float'
      (FloatingLiteral 0x2305ea0 'float' 1.000000))))

llvm-svn: 41412
 2007-08-26 03:29:23 +00:00
Chris Lattner f55ab18663 1) refactor some code. 
2) Add support for lexing imaginary constants (a GCC extension):

t.c:5:10: warning: imaginary constants are an extension
  A = 1.0iF;
         ^

3) Make the 'invalid suffix' diagnostic pointer more accurate:

t.c:6:10: error: invalid suffix 'qF' on floating constant
  A = 1.0qF;
         ^

instead of:

t.c:6:10: error: invalid suffix 'qF' on floating constant
  A = 1.0qF;
      ^

Chris Lattner 1895e58c84 Cases like this: 
char *C;
  C != ((void*)0);

Should not warn about incompatible pointer types.  Also, make sure to
insert an implicit conversion even if the operand is null.

Chris Lattner 27f00282e9 The new correct compound assignment operators exposed a bug in codegen. 
llvm-svn: 41405
 2007-08-25 21:56:20 +00:00
Steve Naroff 46c72915f4 Surpress the UsualUnaryConversions for compound assignment operators. This change 
eliminates the possibility that the left hand expression is an ImplicitCastExpr.
As a result, I removed the check for ImplicitCastExpr in Expr::isLvalue().

This results in the following AST's...

[dylan:~/llvm/tools/clang] admin% cat fix.c

short x; void test4(char c) { 
  x += c; 
  x = x + c;
}
[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang fix.c -parse-ast-dump
Read top-level variable decl: 'x'

void test4(char c)
(CompoundStmt 0x2605d30
  (CompoundAssignOperator 0x2605c40 'short' '+='
    (DeclRefExpr 0x2605c00 'short' Decl='x' 0x2605a80)
    (DeclRefExpr 0x2605c20 'char' Decl='c' 0x2605bc0))
  (BinaryOperator 0x2605d10 'short' '='
    (DeclRefExpr 0x2605c60 'short' Decl='x' 0x2605a80)
    (ImplicitCastExpr 0x2605d00 'short'
      (BinaryOperator 0x2605ce0 'int' '+'
        (ImplicitCastExpr 0x2605cc0 'int'
          (DeclRefExpr 0x2605c80 'short' Decl='x' 0x2605a80))
        (ImplicitCastExpr 0x2605cd0 'int'
          (DeclRefExpr 0x2605ca0 'char' Decl='c' 0x2605bc0))))))

 2007-08-25 18:15:16 +00:00
Steve Naroff e2562ff99d Change Expr::isLvalue() to properly deal with ImplicitCastExpr's. 
This fixes the following bug...

t.c:1:31: error: expression is not assignable
short x; void foo(char c) { x += c; }

This case, among others are now captured in implicit-casts.c.

Steve Naroff aac9415bfb Give CXXBoolLiteralExpr a type (all expressions need a valid type). 
This fixes the following:
