1371 # Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.

1373 # and currently only case is Android: this is almost identical to
1374 # {x86,arm,mips}-linux, but not quite. So this introduces the concept of
1375 # platform variant tags, which get passed in the compile as
1376 # -DVGPV_<arch>_<os>_<variant> along with the main -DVGP_<arch>_<os> definition.
1377 #
1378 # In almost all cases, the <variant> bit is "vanilla". But for Android
1379 # it is "android" instead.

1382 #
1383 # -DVGP_arm_linux -DVGPV_arm_linux_vanilla

1385 # whilst an Android build would have
1386 #
1387 # -DVGP_arm_linux -DVGPV_arm_linux_android
