# NAME:
|
|
# target-flags.mk - target specific flags
|
|
#
|
|
# DESCRIPTION:
|
|
# Include this macro file after all others in a makefile and
|
|
# follow it with any target specific flag settings.
|
|
# For each such variable v in TARGET_FLAG_VARS we set:
|
|
#.nf
|
|
#
|
|
# _$v := ${$v}
|
|
# $v = ${${v}_${.TARGET:T}:U${_$v}}
|
|
#.fi
|
|
#
|
|
# This allows one to do things like:
|
|
#.nf
|
|
#
|
|
# TARGET_FLAG_VARS= CFLAGS
|
|
# .include <target-flags.mk>
|
|
# CFLAGS_fu.o = ${_CFLAGS:N-Wall}
|
|
#.fi
|
|
#
|
|
# To turn off -Wall for just the target fu.o
|
|
# Actually CFLAGS is the default value for TARGET_FLAG_VARS.
|
|
#
|
|
# BUGS:
|
|
# One must be careful to avoid creating circular references in
|
|
# variables. The original version of this macro file did
|
|
# elaborate things with CFLAGS. The current, simpler
|
|
# implementation is ultimately more flexible.
|
|
#
|
|
# It is important that target-flags.mk is included after other
|
|
# macro files and that target specific flags that may reference
|
|
# _$v are set after that.
|
|
#
|
|
# Only works with a make(1) that does nested evaluation correctly.
