Hello Alec Roelke, Brandon Potter,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#3).
Change subject: arch-riscv,sim: Support clone syscall in RISC-V

arch-riscv,sim: Support clone syscall in RISC-V
(1) This patch sets a correct order of clone syscall's arguments for
RISC-V. Linux kernel 4.15 uses CLONE_BACKWARDS flag by default for
RISC-V. The flag in the Linux kernel defines the list of clone syscall's
arguments in the following order:
clone_flags (flags)
newsp (newStack)
parent_tidptr (ptidPtr)
tls (tlsPtr)
child_tidptr (ctidPtr)
Code reference:
https://github.com/riscv/riscv-linux/blob/master/kernel/fork.c
https://github.com/riscv/riscv-linux/blob/master/arch/riscv/Kconfig
(2) This patch copies a parent thread's register values to its child
thread in clone syscall.
