 Yes, though for RISC-V compiler it is a bit ambiguous who the upstream
 is.  As far as I can tell the RISC-V people have only done their MD for
 gcc 4.6.something and 4.9, so it may be Matt(??) who moved this into 4.8.3.
 If I can get one of the supported RISC-V compilers to build I can try it
 to see if it gets the same ICE and report that, otherwise the workaround
 may need to stay until NetBSD moves to a gcc version they also support.
