1373 # Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.
1374 # But there are times where we need a bit more control. The motivating
1375 # and currently only case is Android: this is almost identical to
1376 # {x86,arm,mips}-linux, but not quite. So this introduces the concept of
1377 # platform variant tags, which get passed in the compile as
1378 # -DVGPV_<arch>_<os>_<variant> along with the main -DVGP_<arch>_<os> definition.
1379 #
1380 # In almost all cases, the <variant> bit is "vanilla". But for Android
1381 # it is "android" instead.
1382 #

1384 #
1385 # -DVGP_arm_linux -DVGPV_arm_linux_vanilla

1387 # whilst an Android build would have
1388 #
1389 # -DVGP_arm_linux -DVGPV_arm_linux_android
