Bug ID: 80371
Summary: std::is_integral and std::is_floating_point fail with
vector types
Product: gcc
Version: 6.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jwjagersma at gmail dot com
Target Milestone: ---
Testing with std::is_integral<T> or std::is_floating_point<T> fails for vector
types. I don't think that's supposed to happen.
$ cat vectest.cpp
#include <type_traits>
using Vi [[gnu::vector_size(4 * sizeof(int))]] = int;
using Vf [[gnu::vector_size(4 * sizeof(float))]] = float;
static_assert(std::is_integral<Vi>::value, "");
static_assert(std::is_floating_point<Vf>::value, "");
$ g++ vectest.cpp
vectest.cpp:6:1: error: static assertion failed
static_assert(std::is_integral<Vi>::value, "");
^~~~~~~~~~~~~
vectest.cpp:7:1: error: static assertion failed
static_assert(std::is_floating_point<Vf>::value, "");
^~~~~~~~~~~~~
$ g++ -v
Using built-in specs.
