This fixes the ICE:

However, I am getting errors from the assembler:

ARM mode
pr79904.s:30: Error: selected processor does not support `wldrd wr2,.L2' in ARM

in ARM mode
pr79904.s:33: Error: selected processor does not support `wstrd wr0,[r3]' in

I am compiling with arm-eabi-gcc -mcpu=iwmmxt.
These errors are unrelated to the PR, but I am wondering why they appear?
