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

Package Overview for SoftFloat Release 2a

SoftFloat is a software implementation of floating-point that conforms to
|
|
the IEC/IEEE Standard for Binary Floating-Point Arithmetic. SoftFloat is
|
|
distributed in the form of C source code. Compiling the SoftFloat sources
|
|
generates two things:
|
|
|
|
-- A SoftFloat object file (typically `softfloat.o') containing the complete
|
|
set of IEC/IEEE floating-point routines.
|
|
|
|
-- A `timesoftfloat' program for evaluating the speed of the SoftFloat
|
|
routines. (The SoftFloat module is linked into this program.)
|
|
|
|
The SoftFloat package is documented in four text files:
|
|
|
|
softfloat.txt Documentation for using the SoftFloat functions.
|
|
softfloat-source.txt Documentation for compiling SoftFloat.
|
|
softfloat-history.txt History of major changes to SoftFloat.
|
|
timesoftfloat.txt Documentation for using `timesoftfloat'.
|
|
|
|
Other files in the package comprise the source code for SoftFloat.
|
|
|
|
Please be aware that some work is involved in porting this software to other
|
|
targets. It is not just a matter of getting `make' to complete without
|
|
error messages. I would have written the code that way if I could, but
|
|
there are fundamental differences between systems that I can't make go away.
|
|
You should not attempt to compile SoftFloat without first reading both
|
|
`softfloat.txt' and `softfloat-source.txt'.
|
|
|
|
At the time of this writing, the most up-to-date information about
|
|
SoftFloat and the latest release can be found at the Web page `http://
|
|
HTTP.CS.Berkeley.EDU/~jhauser/arithmetic/SoftFloat.html'.
