[PATCH v1 16/25] tests/tcg/tricore: Add macros to create tests and first test 'abs' |
Date: |
Mon, 19 Apr 2021 15:54:26 +0100 |
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.
