asm

Assembly support, used by tools such as gas and nasm

To declare targets using assembly:

def configure(conf):
        conf.load('gcc gas')

def build(bld):
        bld(
                features='c cstlib asm',
                source = 'test.S',
                target = 'asmtest')

        bld(
                features='asm asmprogram',
                source = 'test.S',
                target = 'asmtest')

Support for pure asm programs and libraries should also work:

def configure(conf):
        conf.load('nasm')
        conf.find_program('ld', 'ASLINK')

def build(bld):
        bld(
                features='asm asmprogram',
                source = 'test.S',
                target = 'asmtest')

waflib.Tools.asm.extension(*k)

Decorator that registers a task generator method which will be invoked during the processing of source files for the extension given:

from waflib import Task
class mytask(Task):
        run_str = 'cp ${SRC} ${TGT}'
@extension('.moo')
def create_maa_file(self, node):
        self.create_task('mytask', node, node.change_ext('.maa'))
def build(bld):
        bld(source='foo.moo')

class waflib.Tools.asm.asm_parser(nodepaths=None, defines=None)

filter_comments(node)

Filter the comments from a c/h file, and return the preprocessor lines. The regexps waflib.Tools.c_preproc.re_cpp, waflib.Tools.c_preproc.re_nl and waflib.Tools.c_preproc.re_lines are used internally.

Returns

the preprocessor directives as a list of (keyword, line)

Return type

a list of string pairs

class waflib.Tools.asm.asm(*k, **kw)
