re PR fortran/36276 (possible issue with opening fortran files?)
PR target/36276
* config/m32r/m32r.c (gen_compare): Removed a rule addsi3 codes to avoid a miss
optimizing at simplify_relational_operation().
* config/m32r/m32r.md (seq): Ditto. Changed reg_or_eq_int16_operand to
reg_or_uint16_operand because seq_insn has not used addsi3 already.
(seq_insn): Ditto. Removed operand check mode "P".
Changed reg_or_eq_int16_operand to reg_or_uint16_operand.
