STATUS: This port is available as of release 0.3.18 of NuttX. The port is basically
complete and many examples run correctly. However, there are remaining instabilities
that make the port un-usable. The nature of these is not understood; the behavior is
that certain SH-1 instructions stop working as advertised. This could be a silicon
problem, some pipeline issue that is not handled properly by the gcc 3.4.5 toolchain
(which has very limited SH-1 support to begin with), or perhaps with the CMON debugger.
At any rate, I have exhausted all of the energy that I am willing to put into this cool

INSTALLATION
^^^^^^^^^^^^
Download and unpack the NuttX tarball. If you are reading this, then you
have probably already done that. After unpacking, you will end up with a
directory called nuttx-version (where version is the NuttX version number).
You might want to rename that directory nuttx to match the various instructions
in the documentation and some scripts in the source tree.
Download and Unpack:
That nuttx build directory should reside in a path that contains no spaces
in the higher level directory names. For example, under Cygwin, your home
directory might be formed from your first and last names like: "/home/First Last".
That will cause strange errors when the make system tries to build.

A Note about Header Files:
NuttX compiles without using the standard header files that are
distributed with your toolchain. That is correct behavior in most
cases because the header files bundled with your toolchain (such as
stdio.h) are probably not correct for use with NuttX. Certain
header files, such as setjmp.h, may be needed from your toolchain.
In that case, one solution is to copy that file from your toolchain
into the NuttX include directory. If you prefer to use the stdint.h
and stdbool.h header files from your toolchain, those could be copied
too. Using most other header files from your toolchain would probably
cause errors.

^^^^^^^^^^^^^^
The mc68hcs12 compilation is prone to errors like the following:
CC: lib_b16sin.c
lib_b16sin.c: In function `b16sin':
lib_b16sin.c:110: error: unable to find a register to spill in class `S_REGS'
lib_b16sin.c:110: error: this is the insn:

(expr_list:REG_NO_CONFLICT (reg/v:SI 54 [ rad ])
(nil))))
lib_b16sin.c:110: confused by earlier errors, bailing out
There are several ways that this error could be fixed:
1. Increase the number of soft regiaters (i.e., "fake" registers defined
at fixed memory locations). This can be done by adding something like
-msoft-reg-count=4 to the CFLAGS. This approach was not taken
because:
- This slows hcs12 performance
- All of these soft registers wouil have to be saved and restored
on every interrupt and context switch.
2. Lowering the optimization level. Also not desireable becauase 99% of the
files that do not have this problem also increase in size. Special case
compilation with reduced optimization levels just for the files that need
it could be done, but this would complicate the make system.
3. Restructuring files to reduce the complexity. If you add local variables
to hold intermediate computational results, this error can be eliminated.
This is the approach taken in NuttX. It has disadvantages only in that
(1) it takes some effort and good guessing to eliminate the problem, and (2)
the problem is not really eliminated -- it can and will re-occur when files
are changed or new files are added.
