I have sent the TriCore tcg-tests series to the list. Cheers, Bastian

Can someone elighten me on how to properly use this? The configure script in tests/tcg/configure.sh will probe for available cross compilers (or take a passed in one). Failing that you can fall back to a docker image which has the compilers included. The result should end up in: $(BUILD_DIR)/tests/tcg/config-$(PROBE_TARGET).mak Assuming you have a CROSS_CC_GUEST or DOCKER_IMAGE and DOCKER_CROSS_CC_GUEST defined there the makefiles should allow building of the tests. For linux-user we include the tests/tcg/multiarch/Makefile.target as well as the target specific one. The CC variable should already be setup to build either via docker or using the installed setup. We don't have a linker or assembler in the tooling so everything is invoked via the compiler with the appropriate flags to call the sub-tools if required. Most rules are single file compile and link. For softmmu tests things are a bit more bespoke. The tooling will make sure things are setup and then include tests/tcg/multiarch/system/Makefile.softmmu-target and tests/tcg/$ARCH/Makefile.softmmu-target. The main purpose of the arch specific Makefile is to provide the appropriate build instructions to build a system image for the multiarch tests and any target specific tests. To support the multiarch tests you need a boot.S and a kernel.ld that defines a simple boot and a __sys_outc helper function. There is a minilib which provides for a basic printf like output. The boot should call main and then return the int code via some mechanism to signal the pass/fail of the test. For aarch64 this is done with semihosting.

How do I add my tcg tests to check-tcg?
Hi Alex, I have some time again to integrate my tcg tests patch for TriCore [1]. However, I'm struggeling a bit to get through the details of the Makefiles. I'm assuming the right rule to run is 'make check-tcg'. I tried running that for xtensa-softmmu, arm-softmmu, and aarch64-softmmu, but they are always skipped. Digging into the Makefiles I found that there is some way to use the dockerfiles to run the test. Can someone elighten me on how to properly use this? Thanks and cheers, Bastian [1] https://lists.nongnu.org/archive/html/qemu-devel/2018-05/msg00074.html
