correct Research Unix edition "appeared in" use in HISTORY

2020-02-08T01:09:57Z

Starting from "Combined Table of Contents" in Doug McIlroy's "A Research UNIX Reader" a table of which edition manuals appeared in. Checked against manuals from bitsavers/TUHS and source from TUHS where available. Ingo points out there are cases where something is included but not documented until a later release. bcd(6) v6 v7 printf(3) v2 v4 abort(3) v5 v6 system(3) v6 v7 fmod(3) v5 v6 ok schwarze@

This is inside !(defined(__amd64__) || defined(__i386__)), while the file is only used on those two architectures. "Free commit! No strings attached! No hidden tricks!" from miod

This became possible because copies of the original v1 manuals have shown up on the Internet some time ago. Reminded by Sevan Janiyan .

Setting and getting the rounding mode on our arm64 FPU has not worked

2019-03-12T22:14:50Z

in libm since the rounding mode is in fpcr, not fpsr. Since both FPU registers are 32-bit we can store them in the 64-bit fenv_t to make handling the bits easier. While there add FE_DENORMAL, which also exists on x86. Also make sure that whenever we are being passed an exception mask, we only allow the bits that are supported by hardware. Found by regression tests Debugged with Moritz Buhl ok kettenis@

Remove the unused leftovers of the 4.4BSD libm, which was only used

on non-IEEE platforms. Since the VAX port was discontinued, all our remaining architectures use IEEE floating point, as will any future ones. ok millert@ tb@
