2019-09-10tests/tcg: move configuration to a sub-shell scriptPaolo Bonzini
Avoid the repeated inclusions of config-target.mak, which have risks of namespace pollution, and instead build minimal configuration files in a configuration script. The same configuration files can also be included in Makefile and Makefile.qemu [AJB 10/09/19] In the original PR this had inadvertently enabled tests for ppc64abi32. However as the rest of the multiarch tests work rather than disabling the otherwise correctly functioning build I've just skipped the failing linux-test test. For some reason I can't debug it with TCG so I'm leaving that to the PPC maintainers to look at.

2019-09-10tests/tcg: cleanup Makefile inclusionsPaolo Bonzini
Rename Makefile.probe to Makefile.prereqs and make it actually define rules for the tests. Rename Makefile to Makefile.target, since it is not a toplevel makefile. Rename Makefile.include to Makefile.qemu and disentangle it from the QEMU Makefile.target, so that it is invoked recursively by tests/Makefile.include. Tests are now placed in tests/tcg/$(TARGET). Drop the usage of TARGET_BASE_ARCH, which is ignored by everything except x86_64 and aarch64. Fix x86 tests by using -cpu max and, while at it, standardize on QEMU_OPTS for aarch64 tests too.

2019-09-10tests/tcg: use EXTRA_CFLAGS everywherePaolo Bonzini
For i386 specifically, this allows using the host GCC to compile the i386 tests. But, it should really be done for all targets, unless we want to pass $(EXTRA_CFLAGS) directly as part of $(CC).

2019-06-13target/arm: Fix output of PAuth AuthRichard Henderson
The ARM pseudocode installs the error_code into the original pointer, not the encrypted pointer. The difference applies within the 7 bits of pac data; the result should be the sign extension of bit 55. Add a testcase to that effect.

2019-05-28tests/tcg/multiarch: expand system memory test to cover moreAlex Bennée
Expand the memory test to cover move of the softmmu code. Specifically we: - improve commentary - add some helpers (for later BE support) - reduce boiler plate into helpers - add signed reads at various sizes/offsets - required -DCHECK_UNALIGNED Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
2019-05-28tests/tcg/aarch64: add system boot.SAlex Bennée
This provides the bootstrap and low level helper functions for an aarch64 kernel. We use semihosting to handle test output and exiting the emulation. semihosting's parameter passing is a little funky so we end up using the stack and pointing to that as the parameter block.

2019-03-12tests/tcg/arm: account for pauth randomnessAlex Bennée
Pointer authentication isn't guaranteed to always detect a clash between different keys. Take this into account in the test by running several times and checking the percentage hit rate of the test.

2018-06-20tests/tcg: add run, diff, and skip helper macrosAlex Bennée
As we aren't using the default runners for all the test cases it is easy to miss out things like timeouts. To help with this we add some helpers and use them so we only need to make core changes in one place.
