| # But there are times where we need a bit more control. The motivating |
| # and currently only case is Android: this is almost identical to arm-linux, |
| # but not quite. So this introduces the concept of platform variant tags, |
| # which get passed in the compile as -DVGPV_<arch>_<os>_<variant> along |
| # with the main -DVGP_<arch>_<os> definition. |
| # |
| # In almost all cases, the <variant> bit is "vanilla". But for Android |
| # it is "android" instead. |
| # |
| # Consequently (eg), plain arm-linux would build with |
| # |
| # -DVGP_arm_linux -DVGPV_arm_linux_vanilla |
| # |
| # whilst an Android build would have |
| # |
| # -DVGP_arm_linux -DVGPV_arm_linux_android |
