Chris Lattner d235d162d0 change print methods to render into a string, which is more useful for diagnostics 
and for handling precedence of types more accurately

llvm-svn: 39177
 2006-11-13 06:22:30 +00:00
Chris Lattner 7ccecb90d4 Implement parsing, printing and AST'ing of array types (except for the bounds). 
This allows us to handle:

int (*A)[restrict static 4][6];

for example.

Chris Lattner 47814666e1 Implement and use isa/dyncast/cast etc for Type classes.

 2006-11-12 00:56:20 +00:00
Chris Lattner d5973ebbe2 Teach ASTContext to delete all created types in its dtor. 
Teach getPointerType to (stupidly) memoize all created pointers.
Give types an enum so we can implement classof.

 2006-11-12 00:53:46 +00:00
Chris Lattner 970e54e3ac Build ASTs for the pointer qualifiers on declarators. This allows us to 
parse (and print) things like:

int* const* restrict* const volatile***

etc.

Chris Lattner aecbefa519 We can now parse and remember the distinction between: 
'unsigned char' and 'unsigned char const'.

Chris Lattner 288e86ff15 Rename SemaDeclSpec.{h|cpp} back to DeclSpec.{h|cpp} now that the distinction 
between sema and parse is clear.

to SemaDecl.cpp

llvm-svn: 39159
 2006-11-10 05:29:30 +00:00
Chris Lattner bd638926e2 remove diag helper that implicitly reports the diagnostic at the current 
token: it is better for the code to be explicit.

llvm-svn: 39158
 2006-11-10 05:19:25 +00:00
Chris Lattner eaafe122b6 move semantic analysis of break/continue out of the parser into the sema class.

llvm-svn: 39151
 2006-11-09 06:34:47 +00:00
Chris Lattner 697e5d692b Change courses on how we do semantic analysis. Semantic analysis 
fundamentally requires having an AST around, so move all sema to the
AST library.  This is the first step, later steps will be needed to
clean up libast.

Chris Lattner b6a0e1781f implement trivial scope caching. This reduces malloc traffic in the common 
case, speeding up parsing of this contrived example:

#define A {{}}
#define B A A A A A A A A A A
#define C B B B B B B B B B B
#define D C C C C C C C C C C
#define E D D D D D D D D D D
#define F E E E E E E E E E E
#define G F F F F F F F F F F
#define H G G G G G G G G G G

void foo() {
  H
}

from 7.478s to 4.321s.  GCC requires 8.2s.

Chris Lattner 33ad2cacc9 Make Scope keep track of the kind of scope it is. Properly scope loop and 
switch statements.  Make break/continue check that they are inside of an
appropriate control-flow construct.  This implements Parser/bad-control.c.
