# We have several orthogonal cases we'd like to test:
# A32 vs T32 vs A64
# old syscall vs new HLT (for A32 and T32)
# usermode vs system
# gdb syscalls vs normal
# This makefile tests all of the instruction set and user/system cases.
# short instructions:
# make run QEMU_BUILDDIR=path-to-your-builddir
# To test gdb attached syscalls:
# make run-usertest-a32 QEMU_BUILDDIR=path-to-builddir GDBPORT=1234
# then in another terminal run gdb and connect it to port 1234.
# (Note that gdb's working directory must be the one with the testdata.txt
# file in it, since filename resolution is done on the gdb end.)
# Repeat for the other tests.
# TODO: compare test output against a golden reference rather
# than just letting it dump to stdout/stderr.
