[llvm-dev] Segmentation fault when using llc to target riscv.

[Ahmed Samara via llvm-dev]

I am using LLVM version 4.0.1

Running `llc -march=riscv64 math.ll` returns:

#0 0x0000000000fed7d1 (llc+0xfed7d1)
#1 0x0000000000fec559 (llc+0xfec559)

Stack dump:

Segmentation fault (core dumped)


It works fine when I use any other argument for -march (x86, arm, arm64).
