There is important information about booting non-ack images in docs/UPDATING. ack/aout-format images can't be built any more, and booting clang/ELF-format ones is a little different. Updating to the new boot monitor is recommended. Changes in this commit: . drop boot monitor -> allowing dropping ack support . facility to copy ELF boot files to /boot so that old boot monitor can still boot fairly easily, see UPDATING . no more ack-format libraries -> single-case libraries . some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases . drop several ack toolchain commands, but not all support commands (e.g. aal is gone but acksize is not yet). . a few libc files moved to netbsd libc dir . new /bin/date as minix date used code in libc/ . test compile fix . harmonize includes . /usr/lib is no longer special: without ack, /usr/lib plays no kind of special bootstrapping role any more and bootstrapping is done exclusively through packages, so releases depend even less on the state of the machine making them now. . rename nbsd_lib* to lib* . reduce mtree

Release 2a (1998 December)
|
|
|
|
-- Added functions to convert between 64-bit integers (int64) and all
|
|
supported floating-point formats.
|
|
|
|
-- Fixed a bug in all 64-bit-version square root functions except
|
|
`float32_sqrt' that caused the result sometimes to be off by 1 unit in
|
|
the last place (1 ulp) from what it should be. (Bug discovered by Paul
|
|
Donahue.)
|
|
|
|
-- Improved the makefiles.

Release 2 (1997 June)
|
|
|
|
-- Created the 64-bit (bits64) version, adding the floatx80 and float128
|
|
formats.
|
|
|
|
-- Changed the source directory structure, splitting the sources into a
|
|
`bits32' and a `bits64' version. Renamed `environment.h' to `milieu.h'
|
|
(to avoid confusion with environment variables).
|
|
|
|
-- Fixed a small error that caused `float64_round_to_int' often to round the
|
|
wrong way in nearest/even mode when the operand was between 2^20 and 2^21
|
|
and halfway between two integers.

Release 1a (1996 July)
|
|
|
|
-- Corrected a mistake that caused borderline underflow cases not to raise
|
|
the underflow flag when they should have. (Problem reported by Doug
|
|
Priest.)
|
|
|
|
-- Added the `float_detect_tininess' variable to control whether tininess is
|
|
detected before or after rounding.
