Markus Armbruster	5e5197b136	Supply missing header guards ... Backports applicable parts of commit f91005e195e7e1485e60cb121731589960f1a3c9 from qemu	2019-06-12 10:59:10 -04:00
Kito Cheng	bd3e9ebaea	RISC-V: linux-user support for RVE ABI ... This change checks elf_flags for EF_RISCV_RVE and if present uses the RVE linux syscall ABI which uses t0 for the syscall number instead of a7. Warn and exit if a non-RVE ABI binary is run on a cpu with the RVE extension as it is incompatible. Backports relevant parts of 5836c3eccedb6dfab16b8f606f2de24b8938b69c from qemu	2019-03-19 23:58:31 -04:00
Lioncash	b6f752970b	target/riscv: Initial introduction of the RISC-V target ... This ports over the RISC-V architecture from Qemu. This is currently a very barebones transition. No code hooking or any fancy stuff. Currently, you can feed it instructions and query the CPU state itself. This also allows choosing whether or not RISC-V 32-bit or RISC-V 64-bit is desirable through Unicorn's interface as well. Extremely basic examples of executing a single instruction have been added to the samples directory to help demonstrate how to use the basic functionality.	2019-03-08 21:46:10 -05:00
