--- Comment #13 from Tobias Schlüter <tobi at gcc dot gnu.org> ---
I'm sorry to say that the problem is NOT fixed on the trunk. With "ARM64 gcc
trunk" on the compiler explorer, we get the below. OTOH 9.3 produces perfect
code. Compiler explorer link: https://godbolt.org/z/56h67rfc4
.LC0:
.string "Eigen::internal::variable_if_dynamic<T,
Value>::variable_if_dynamic(T) [with T = long int; int Value = 0]"
.LC1:
.string
"/opt/compiler-explorer/libs/eigen/v3.3.9/Eigen/src/Core/util/XprHelper.h"
.LC2:
.string "v == T(Value)"
.LC3:
.string "Eigen::internal::variable_if_dynamic<T,
Value>::variable_if_dynamic(T) [with T = long int; int Value = 3]"
.LC4:
.string "Eigen::internal::variable_if_dynamic<T,
Value>::variable_if_dynamic(T) [with T = long int; int Value = 4]"
.LC5:
.string "Eigen::internal::variable_if_dynamic<T,
Value>::variable_if_dynamic(T) [with T = long int; int Value = 1]"
