# Configuration for Linux on ARM.

# 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 similar to the preprocessor

# defines in build/core/combo/include/arch/<combo>/AndroidConfig.h. 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.
