Subject: [PATCH v2 16/30] tests/tcg/tricore: Add macros to create tests and first test 'abs'
Date: Tue,  4 May 2021 11:02:09 +0100	[thread overview]
Message-ID: <20210504100223.25427-17-alex.bennee@linaro.org> (raw)
In-Reply-To: <20210504100223.25427-1-alex.bennee@linaro.org>

From: Bastian Koppelmann <kbastian@mail.uni-paderborn.de>

This kind of tests is inspired by the riscv-tests repository. This adds
macros that makes it easy to create single instruction self containing
tests.

It is achieved by macros that create a test sequence for an
instruction and check for a supplied correct value. If the value is correct the
next instruction is tested. Otherwise we jump to fail handler that writes is
test number as a status code back to qemu that then exits on that status code.
If all tests pass we write back 0 as a status code and exit.
