<div dir="ltr">Hi Marshall,<div><br></div><div>gcc 4.7 added enough frontend support to implement most (not all) of type_traits. Here's a patch that enables std::underlying_type.</div><div><br></div><div>FYI, this is a first in a series of ~3 that will allow most libc++ tests for type_traits and atomics to pass on gcc >= 4.7. Will send those out as I manage to get them fully cleaned up.</div>
