# This is an gyp include to use YASM for compiling assembly files.
|
||
|
|
#
|
||
|
|
# Files to be compiled with YASM should have an extension of .asm.
|
||
|
|
#
|
||
|
|
# There are three variables for this include:
|
||
|
|
# yasm_flags : Pass additional flags into YASM.
|
||
|
|
# yasm_output_path : Output directory for the compiled object files.
|
||
|
|
# yasm_includes : Includes used by .asm code. Changes to which should force
|
||
|
|
# recompilation.
|
||
|
|
#
|
||
|
|
# Sample usage:
|
||
|
|
# 'sources': [
|
||
|
|
# 'ultra_optimized_awesome.asm',
|
||
|
|
# ],
