The problem seems to be that the extra call to build_distinct_type_copy() also creates new TYPE_{MIN,MAX}_VALUEs that are not compatible/the same as the base type itself. The simple "fix" is to actually remove the unneeded build_distinct_type_copy(), since according to richi, the types returned from make_unsigned_type() are already distinct. gcc/ 2020-10-21 Richard Biener PR target/97360 * config/rs6000/rs6000-call.c (rs6000_init_builtins): Remove call to build_distinct_type_copy(). gcc/testsuite/ 2020-10-21 Martin Liska PR target/97360 * gcc.target/powerpc/pr97360.c: New test.
