Support for register type xxx __asm__(yyy)

[brmmm3]

Is it possible to add support for the following syntax:

register typeName variableName asm("registerName");

Best regards, Martin

Sure, I'd be happy to take a (tested) patch.

(That is to say, a patch that includes tests.)

I would if I would have enough experience to implement this. My current result ist:

def p_asm_register_declarator(self, p):
    """ declaration : declaration_specifiers declarator __ASM__ LPAREN argument_expression_list RPAREN
    """
    storage = p[1]["storage"]
    if not storage or (storage[0] != "register"):
        raise NotImplementedError(
                "register expected here '%s'"
                % list(p))
    decl = c_ast.TypeDecl(
        declname=p[1],
        type=None,
        quals=None,
        coord=self._token_coord(p, 2))
    spec = p[1]
    ty = spec['type']
    c_ast.Decl(
        name=None,
        quals=spec['qual'],
        storage=spec['storage'],
        funcspec=spec['function'],
        type=ty[0],
        init=None,
        bitsize=None,
        coord=ty[0].coord)
    p[0] = self._type_modify_decl(decl, p[2])

But it seems to be wrong because when I convert it back to C-Code then no C-Code is created for this line. I hoped that you as the maintainer have enough experience to quickly implement it.

You need to add the code to the C generator: https://github.com/inducer/pycparserext/blob/master/pycparserext/ext_c_generator.py
