# There are 4 OS/arch pairs:
# - BUILDOS/BUILDARCH: the current machine's pair used for build.
# - HOSTOS/HOSTARCH: pair where syz-manager will run.
# - TARGETOS/TARGETVMARCH: pair of the target OS under test.
# - TARGETOS/TARGETARCH: pair of the target test process.
#
# The last 2 differ for e.g. amd64 OS and 386 test processes (compat syscall testing).
# All pairs default to the current machine. All but BUILD can be overriden.
#
# For example, to test linux/amd64 on linux/amd64, you just run:
# make
# To test linux/arm64 from darwin/amd64 host, run:
# make HOSTOS=darwin HOSTARCH=amd64 TARGETOS=linux TARGETARCH=arm64
# To test x86 compat syscalls, run:
# make TARGETVMARCH=amd64 TARGETARCH=386
#
# There is one special case for extracting constants for Android
# (you don't need this unless you update system call descriptions):
# make extract TARGETOS=android SOURCEDIR=/path/to/android/checkout
