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')
class waflib.Tools.asm.asm(*k, **kw)[source]

Bases: waflib.Task.Task

Compile asm files by gas/nasm/yasm/...

waflib.Tools.asm.asm_hook(self, node)[source]

Bind the asm extension to the asm task

Parameters:node (waflib.Node.Node) – input file
class waflib.Tools.asm.asmprogram(*k, **kw)[source]

Bases: waflib.Tools.ccroot.link_task

Link object files into a c program

class waflib.Tools.asm.asmshlib(*k, **kw)[source]

Bases: waflib.Tools.asm.asmprogram

Link object files into a c shared library

class waflib.Tools.asm.asmstlib(*k, **kw)[source]

Bases: waflib.Tools.ccroot.stlink_task

Link object files into a c static library

waflib.Tools.asm.extension(*k)

Decorator: register 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')
waflib.Tools.asm.feature(*k)

Decorator: register a task generator method that will be executed when the object attribute ‘feature’ contains the corresponding key(s):

from waflib.Task import feature
@feature('myfeature')
def myfunction(self):
        print('that is my feature!')
def build(bld):
        bld(features='myfeature')
Parameters:k (list of string) – feature names

Bases: waflib.Tools.ccroot.link_task

Base for static link tasks, which use ar most of the time. The target is always removed before being written.

Bases: waflib.Task.Task

Base class for all link tasks. A task generator is supposed to have at most one link task bound in the attribute link_task. See waflib.Tools.ccroot.apply_link().

Process the target attribute to add the platform-specific prefix/suffix such as .so or .exe. The settings are retrieved from env.clsname_PATTERN
