            Bug ID: 59809
           Summary: template non-type parameter in nested class-template
                    said not be declared
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c++

          Reporter: jorenheit at gmail dot com

The following code results in a compiler error on GCC 4.7.2:

gccbug.cc:8:15: error: ‘V’ was not declared in this scope

Code:

// -----------------------
// gccbug.cc
template <typename T>
struct S
{
    template <int V>
    struct Inner
    {
        int a{V};
    };
};
// -----------------------

Output of gcc -v:

            Bug ID: 59810
           Summary: [AArch64] LDn/STn implementations are not
                    ABI-conformant for bigendian.
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: belagod at gcc dot gnu.org

Permuted loads/stores implemented in the aarch64 backend do not conform to
AArch64 ABI for bigendian. The ABI states that

"... On a little endian system this means that element 0 will always contain
the lowest addressed element of a short vector; on a big endian system element
0 will contain the highest addressed element of a short vector."

In the implementations of vec_loadlanes and vec_storelanes in aarch64-simd.md,
they are just loaded lane-wise for both endianness. This may be correct for
little endian, but for bigendian, this is the reversed order. Because the
architecture does not offer a way to perform opaque loads/stores(LDR q, STR q)
for permuted loads, the lanes will need to be reversed after permuted loading
and reversed before permuted storing.
