When I read the RTL dumps correctly, gcc tries to assign SP to wCGR0.
This can be done by the
tmrc sp, wCGR0
assembly instruction which will be issued by alternative 6 in
--- iwmmxt.md ---
(define_insn "*iwmmxt_movsi_insn"
[(set (match_operand:SI 0 "nonimmediate_operand" "=rk,r,r,rk, m,z,r,?z,Uy,z")
(match_operand:SI 1 "general_operand" "rk, I,K,mi,rk,r,z,Uy,z,
z"))]
...
case 6: return \"tmrc\\t%0, %1\";
The corresponding constraints pair is ['r', 'z'] and it is matched by
[sp, wcgr0] afais. What could be the reason for the ICE?
