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). -- Joseph S.
