From 92d70b77ebb45ec43c163d7ebfe7a3c613c24621 Mon Sep 17 00:00:00 2001 From: Thomas Munro Date: Mon, 11 Jul 2022 11:50:41 +1200 Subject: [PATCH] Tidy up claimed supported CPUs and OSes. * Remove arbitrary mention of certain endianness and bitness variants; it's enough to say that applicable variants are expected to work. * List RISC-V (known to work, being tested). * List SuperH and M88K (code exists, unknown status, like M68K). * De-list VAX and remove code (known not to work). * Remove stray trace of Alpha (support was removed years ago). * List illumos, DragonFlyBSD (known to work, being tested). * No need to single Windows out by listing a specific version, when we don't do that for other OSes; it's enough to say that we support current versions of the listed OSes (when 16 ships, that'll be Windows 10+).
