"""

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(

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')
