AFAICS, I don't think it mandates a double-rounding behavior for double to

It's not a change between the two versions of ACLE.  It's a change
relative to the early (pre-ACLE) __fp16 specification (or, at least, a
clarification thereto in email on 12 Aug 2008) that was used as a basis
for the original implementation of __fp16 in GCC (and that thus is what's
currently implemented by GCC and tested for in the testsuite).


Hi Joseph,

I can't seem to find that email on gcc-patches circa August 2008 - which listwas it sent to?


Thanks,
Tejas.
