| # This file is meant to be included into a target to provide an action |
| # to generate C header files. These headers include definitions |
| # that can be used in ARM assembly files. |
| # |
| # To use this, create a gyp target with the following form: |
| # { |
| # 'target_name': 'my_asm_headers_lib', |
| # 'type': 'static_library', |
| # 'sources': [ |
| # 'foo.c', |
| # 'bar.c', |
| # ], |
| # 'includes': ['path/to/this/gypi/file'], |
| # } |
| # |
| # The headers are guaranteed to be generated before any |
| # source files, even within this target, are compiled. |
| # |
| # The 'asm_header_dir' variable specifies the path suffix that output |
| # files are generated under. |
| |
| # TODO(kma): port this block from Android into other build systems. |
