1351 # Platform variants?
1352 #----------------------------------------------------------------------------
1354 # Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.
1355 # But there are times where we need a bit more control. The motivating
1356 # and currently only case is Android: this is almost identical to
1357 # {x86,arm,mips}-linux, but not quite. So this introduces the concept of
1358 # platform variant tags, which get passed in the compile as
1359 # -DVGPV_<arch>_<os>_<variant> along with the main -DVGP_<arch>_<os> definition.
1360 #
1361 # In almost all cases, the <variant> bit is "vanilla". But for Android
1362 # it is "android" instead.
1363 #
1364 # Consequently (eg), plain arm-linux would build with
1365 #
1366 # -DVGP_arm_linux -DVGPV_arm_linux_vanilla
1367 #
1368 # whilst an Android build would have
1369 #
1370 # -DVGP_arm_linux -DVGPV_arm_linux_android
1371 #
1372 # Same for x86. The setup of the platform variant is pushed relatively far
1373 # down this file in order that we can inspect any of the variables set above.
