# You can set TARGET_ARCH_VARIANT to use an arch version other
|
|
# than ARMv5TE. Each value should correspond to a file named
|
|
# $(BUILD_COMBOS)/arch/<name>.mk which must contain
|
|
# makefile variable definitions. Their
|
|
# purpose is to allow module Android.mk files to selectively compile
|
|
# different versions of code based upon the funtionality and
|
|
# instructions available in a given architecture version.
|
|
#
|
|
# The blocks also define specific arch_variant_cflags, which
|
|
# include defines, and compiler settings for the given architecture
|
|
# version.
