the fmal failures are a bit concerning:

fmal should be a tail call to fma if long double has the same
representation as double. (can you please verify this? there
should be a single branch instruction in fmal)

there are no fma failures with the same tests so fmal should
work fine too.

may be the libc-test code got miscompiled or somehow wrong?
or long double arithmetics is broken?
