| # 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. |
