--- Comment #3 from Andi Kleen <andi-gcc at firstfloor dot org> ---
Smaller test case:

struct Span {
    int test[5];
};

void resolveToBufferSlow(Span *buffer);

__attribute__((noinline)) void resolveToBuffer(Span *buffer)
{
    buffer->test[0] = 4;
    [[clang::musttail]] return resolveToBufferSlow(buffer);
}
