From 2d934b5951880ba68948e2c42060d53ceb578e06 Mon Sep 17 00:00:00 2001 From: Bastian Koppelmann Date: Wed, 12 May 2021 11:20:36 +0100 Subject: [PATCH] tests/tcg/tricore: Add macros to create tests and first test 'abs' MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
