Passing stack pointer to statepoint-gc
...unction written in assembly that pushes the RSP register to RDI before calling into the runtime, so that the runtime gc polling function can read it as a parameter.
I was trying to do the same thing except in llvm, so from my gc.safepoint_poll definition, I tried adding these lines:
declare void @runtime_safepoint_poll(i64)
