# Parse the NASM version file and produce appropriate macros
|
|
#
|
|
# The NASM version number is assumed to consist of:
|
|
#
|
|
# <major>.<minor>[.<subminor>][pl<patchlevel>]]<tail>
|
|
#
|
|
# ... where <tail> is not necessarily numeric.
|
|
#
|
|
# This defines the following macros:
|
|
#
|
|
# version.h:
|
|
# NASM_MAJOR_VER
|
|
# NASM_MINOR_VER
|
|
# NASM_SUBMINOR_VER -- this is zero if no subminor
|
|
# NASM_PATCHLEVEL_VER -- this is zero is no patchlevel
|
|
# NASM_VERSION_ID -- version number encoded
|
|
# NASM_VER -- whole version number as a string
|
|
#
|
|
# version.mac:
|
|
# __NASM_MAJOR__
|
|
# __NASM_MINOR__
|
|
# __NASM_SUBMINOR__
|
|
# __NASM_PATCHLEVEL__
|
|
# __NASM_VERSION_ID__
|
|
# __NASM_VER__
