* tests/tcg/tricore: Add macros to create tests and first test 'abs'Bastian Koppelmann2021-05-181-0/+6
| | | | | | | | | | | | | | | | | | | 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.

* tests/tcg: Add docker_as and docker_ld cmdsBastian Koppelmann2021-05-181-1/+16
| | | | | | | | | | | | | | At least for the TriCore target no easily available c compiler exists. Thus we need to rely on "as" and "ld". This allows us to run them through the docker image. We don't test the generation capabilities of docker images as they are assumed to work.

* tests/tcg: don't iterate through other arch compilersAlex Bennée2021-05-181-89/+59Star
| | | | | | | | | | | | | | | | There should only be one compiler per architecture. Those cases where the same compiler can deal with a different architecture should be explicitly set for both cross_cc and docker configurations. Otherwise you get strangeness like: --cross-cc-aarch64=/bin/false causing the logic to attempt to use a locally available arm-linux-gnueabihf-gcc rather than forcing the use of the docker image which is what is implied by the command line option.

* target/ppc: Fix bcdsub. emulation when result overflowsFabiano Rosas2021-03-091-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit d03b174a83 (target/ppc: simplify bcdadd/sub functions) meant to simplify some of the code but it inadvertently altered the way the CR6 field is set after the operation has overflowed. The CR6 bits are set based on the *unbounded* result of the operation, so we need to look at the result before returning from bcd_add_mag, otherwise we will look at 0 when it overflows. Consider the following subtraction: v0 = 0x9999999999999999999999999999999c (maximum positive BCD value) v1 = 0x0000000000000000000000000000001d (negative one BCD value) bcdsub. v0,v0,v1,0 The Power ISA 2.07B says: If the unbounded result is greater than zero, do the following. If PS=0, the sign code of the result is set to 0b1100. If PS=1, the sign code of the result is set to 0b1111. If the operation overflows, CR field 6 is set to 0b0101. Otherwise, CR field 6 is set to 0b0100. POWER9 hardware: vr0 = 0x0000000000000000000000000000000c (positive zero BCD value) cr6 = 0b0101 (0x5) (positive, overflow) QEMU: vr0 = 0x0000000000000000000000000000000c (positive zero BCD value) cr6 = 0b0011 (0x3) (zero, overflow) <--- wrong This patch reverts the part of d03b174a83 that introduced the problem and adds a test-case to avoid further regressions: before: $ make run-tcg-tests-ppc64le-linux-user (...)

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.
