Bug ID: 87286
Summary: ICE on vectors of enums
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: rsandifo at gcc dot gnu.org
Target Milestone: ---
This testcase:
enum foo { F };
typedef enum foo vec_foo __attribute__((vector_size (16)));
vec_foo add (vec_foo x, vec_foo y) { return x + y; }
triggers:
internal compiler error: in vector_types_compatible_elements_p
This seems to be a disagreement between handle_vector_size_attribute (which
accepts INTEGRAL_TYPE_Ps except BOOLEAN_TYPE) and
vector_types_compatible_elements_p (which uses INTEGER_TYPE instead of
INTEGRAL_TYPE_P). Not sure whether the intent was to forbid vectors of enums,
so not sure whether this is ice-on-valid or ice-on-invalid.
