Chris Lattner 03928c7f9a Make parser scope cache be a member of the parser instead of a global,
which makes it multithread clean.

Chris Lattner 23b7eb677d Finally bite the bullet and make the major change: split the clang namespace
out of the llvm namespace.  This makes the clang namespace be a sibling of
llvm instead of being a child.

The good thing about this is that it makes many things unambiguous.  The
bad things is that many things in the llvm namespace (notably data structures
like smallvector) now require an llvm:: qualifier.  IMO, libsystem and libsupport
should be split out of llvm into their own namespace in the future, which will fix
this issue.

Steve Naroff 0f2fe17ff1 Bug #:
Submitted by:
Reviewed by:
Implement support for GCC __attribute__.

- Implement "TODO" in Parser::ParseAttributes. Changed the return type from
void to Parser::DeclTy. Changed all call sites to accept the return value.
- Added Action::ParseAttribute and Sema::ParseAttribute to return an
appropriate AST node. Added new node AttributeDecl to Decl.h.

Still to do...hook up to the Decl...

Chris Lattner 36982e4367 Add support for inserting up to 10 strings in a diagnostic, with %0, %1, %2,
etc.

Chris Lattner c24278d9a0 Do not invoke objc parser actions when a top level +/- is seen, unless objc
is enabled.

Chris Lattner 83b94e0967 Generalize the skipping logic to allow skipping until any one of a set of
tokens is found.

llvm-svn: 39419
2007-04-27 19:12:15 +00:00
Chris Lattner 7f58c3dfe4 Do not use ParseCompoundStatement to parse the body of a function. This causes
an extra scope stack to be pushed between the function body and arguments, which
causes the parser to incorrectly accept stuff like 'int foo(int A) { int A; }',
which is test/Parser/argument_redef.c.

diagnosing malformed K&R function definitions.

Chris Lattner cbc426d4f7 Next step of retaining information about function prototypes: actually retain
the info.  Also, call Actions.ParseParamDeclaratorType instead of
Actions.ParseDeclarator for parameter type lists: we don't want declaration
objects created when parsing a function declarator, we just want type info.

llvm-svn: 39230
2006-12-02 06:43:02 +00:00
Chris Lattner edc9e39d88 First step towards accurately retaining information about function
parameters: build an array of ParamInfo structures and pass it to the
declarator for safe keeping (it owns the list).

Next step: actually populate the arg array with useful stuff.

Chris Lattner b20e89449f capture sourcelocation info for type specifiers. This improves diagnostics
for things like 'short _Complex'.

llvm-svn: 39227
2006-11-28 05:30:29 +00:00
Chris Lattner 4d8f873b5b record accurate sourceloc info for storage class specs, so we can report
things like:

t.c:4:10: error: invalid storage class specifier in function declarator
int foo2(auto int Aaslfkasdflkj, register B);
         ^

instead of:

t.c:4:19: error: invalid storage class specifier in function declarator
int foo2(auto int Aaslfkasdflkj, register B);
                  ^

Chris Lattner 229ce60fc9 split the ParseFunctionDefinition action into two actions, one which is
called before and one which is called after function definition parsing.

2006-11-21 01:21:07 +00:00
Chris Lattner d0342e5989 Create a new TypeNameType class, which represents typedefs as types. This
allows us to handle stuff like:

typedef int G;
 ..
  X = sizeof(G);

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

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 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

declarations through the asm streamer.  For a testcase like:

int G;

Read top-level decl: G

Read top-level decl: I
