Clang's version of objdump doesn't recognize "setftest.elf" as a dynamic object and produces an error stating such. $ llvm-objdump -R ./arm/selftest.elf arm/selftest.elf: file format elf64-littleaarch64 llvm-objdump: error: './arm/selftest.elf': not a dynamic object This causes the ARM64 "arch_elf_check" check to fail. Using "readelf -rW" is a better option way to get the same information and produces the same information in both binutils and LLVM. Signed-off-by:

Removing some tests which are done at other points in the code implicitly. In lib/s390x/uc.c#setup_uv(void) the rc of the qui result is verified using asserts. The whole test is fenced by lib/s390x/uc.c#uv_os_is_guest(void) that checks if SET and REMOVE SHARED is present. Signed-off-by:

Some instructions are emulated by KVM. Test that KVM correctly emulates storage key checking for two of those instructions (STORE CPU ADDRESS, SET PREFIX). Test success and error conditions, including coverage of storage and fetch protection override. Also add test for TEST PROTECTION, even if that instruction will not be emulated by KVM under normal conditions. Signed-off-by:

Add a basic migration test for s390x. This tests the guarded-storage registers and vector registers are preserved on migration. Check for the respective facilities. Since it is possible neither guarded-storage nor vector are there, add an additional report_pass() such that least one PASS is reported. Signed-off-by:

Add a basic implementation for reading from the SCLP ASCII console. The goal of this is to support migration tests on s390x. To know when the migration has been finished, we need to listen for a newline on our console. Hence, this implementation is focused on the SCLP ASCII console of QEMU and currently won't work under e.g. LPAR. Signed-off-by:

Add a test for SIGP STORE_ADDITIONAL_STATUS order. There are several cases to cover: - when neither vector nor guarded-storage facility is available, check the order is rejected. - when one of the facilities is there, test the order is rejected and adtl_status is not touched when the target CPU is running or when an invalid CPU address is specified. Also check the order is rejected in case of invalid alignment. - when the vector facility is there, write some data to the CPU's vector registers and check we get the right contents. - when the guarded-storage facility is there, populate the CPU's guarded-storage registers with some data and again check we get the right contents. To make sure we cover all these cases, adjust unittests.cfg to run the test with both guarded-storage and vector facility off and on. In TCG, we don't have guarded-storage support, so we just run with vector facility off and on. Signed-off-by:
