	This patch adds instruction tests for the RV64C extension implementation. It also updates existing executables for the latest riscv-tools now that they are compatible.

2017-04-05	riscv: fix compatibility with Linux toolchain	Alec Roelke
	Previously, RISC-V in gem5 only supported RISC-V's Newlib toolchain (riscv64-unknown-elf-) due to incorrect assumptions made in the initial setup of the user stack in SE mode. This patch fixes that by referring to the RISC-V proxy kernel code (https://github.com/riscv/riscv-pk) and setting up the stack according to how it does it. Now binaries compiled using the Linux toolchain (riscv64-unknown-linux-gnu-) will run as well. [Update for recent changes to MemState to add accessors and mutators to get its members.] Change-Id: I6d2c486df7688efe3df54273e9aa0fd686851285 Reviewed-on: https://gem5-review.googlesource.com/2305 Maintainer: Alec Roelke <ar4jc@virginia.edu> Reviewed-by: Brandon Potter <Brandon.Potter@amd.com> Reviewed-by: Jason Lowe-Power <jason@lowepower.com>
2016-11-30	riscv: [Patch 8/5] Added some regression tests to RISC-V	Alec Roelke
	This patch is the eighth patch in a series adding RISC-V to gem5, and third of the bonus patches to the original series of five. It adds some regression tests to RISC-V. Regression tests included: - se/00.hello - se/02.insttest (split into several binaries which are not included due to large size) The tests added to 00.insttest will need to be build manually; to facilitate this, a Makefile is included. The required toolchain and compiler (riscv64-unknown-elf-gcc) can be built from the riscv-tools GitHub repository at https://github.com/riscv/riscv-tools. Note that because EBREAK only makes sense when gdb is running or while in FS mode, it is not included in the linux-rv64i insttest. ERET is not included because it does not make sense in SE mode and, in fact, causes a panic by design. Note also that not every system call is tested in linux-rv64i; of the ones defined in linux/process.hh, some have been given numbers but not definitions for the toolchain, or are merely stubs that always return 0. Of the ones that do work properly, only a subset are tested due to similar functionality. Signed-off by: Alec Roelke Signed-off by: Jason Lowe-Power <jason@lowepower.com>
