Ok, I've tried to make the changes you've suggested @MaskRay , let me know if I've missed something.

On another note, I lost my previous qemu VM and have rebuilt LLVM with this patch in a new one; I am now getting the following issue with the XRay runtime:

SanitizerTool: CHECK failed: sanitizer_allocator_primary32.h:292 "((res)) < ((kNumPossibleRegions))" (0x7fff93a, 0x40000) (tid=24873)

A previous thread (https://reviews.llvm.org/D87580) suggests this might be a qemu issue, but I am using qemu-system-riscv64 (and not qemu user-mode.) However, I figured I'd check anyway.
