This patch adds a subset (rv64*) of RISC-V assembly tests. The original riscv-test project can be found here: https://github.com/riscv/riscv-tests. The riscv-test project is under the BSD license (https://github.com/riscv/riscv-tests/blob/master/LICENSE) and is maintained separately from gem5 project. The tests have been slightly modified to work in gem5 SE mode: (1) Removed a trap handler used in riscv-tests for bare-metal systems (2) Instead of throwing an exception, the tests call the exit syscall with the exit code of - '0' if SUCCESS - Failed test case's number (non-zero) if FAILURE The exit code can be captured after a simuation completes. In addition to original RISC-V assembly tests, this patch adds several assembly tests specifically for AMO, LR, SC and system calls. Those tests target a multi-core system. (1) rv64uamt: multi-threaded tests for A-extension instructions (2) rv64samt: multi-threaded tests for clone and futex system calls This patch also makes the style checker ignore RISC-V assembly test directory. The assembly tests are maintained in an external project that does not follow the gem5 coding conventions. Please find more details in the README file included in this patch.
