during RTL pass: expand
offtime.c: In function '__offtime':
offtime.c:79:6: internal compiler error: RTL check: expected elt 0 type 'e' or
'u', have 'w' (rtx const_int) in riscv_legitimize_const_move, at
config/riscv/riscv.cc:2176
79 | ip = __mon_yday[__isleap(y)];
Tested on rv32gc glibc with --enable-checking=rtl.
gcc/ChangeLog:
* config/riscv/riscv.cc (riscv_legitimize_const_move): Eliminate
src_op_0 var to avoid rtl check error.
