Zhaoshi Zheng	1c466477ad	[RISCV] Support Shadow Call Stack ... Currenlty assume x18 is used as pointer to shadow call stack. User shall pass flags: "-fsanitize=shadow-call-stack -ffixed-x18" Runtime supported is needed to setup x18. If SCS is desired, all parts of the program should be built with -ffixed-x18 to maintain inter-operatability. There's no particuluar reason that we must use x18 as SCS pointer. Any register may be used, as long as it does not have designated purpose already, like RA or passing call arguments. Differential Revision: https://reviews.llvm.org/D84414	2020-09-17 16:02:35 -07:00
