Naming Conventions
------------------
    The basic naming convention for Unix machines is that
    hppa1.1-hp-proelf- is prepended to the front of each tool
    name. For DOS machines, the names are truncated to just the base
    tool name, like GCC.

Installation
------------
    For this beta release, there are three tar files on the tape. A
    simple "tar xvf [device name]" will work. One of the tarfiles is
    all the sources, the others are binaries. One set is for a HP-UX
    host, and the other set is for a sun4 host.

    First, make a directory called /usr/cygnus/beta-941019. Cd into
    this directory and type the tar command to extract the three tar
    files. Once the tar files are off the tape, you can uncompress
    and extract them. Typically, once they are installed, it's common
    practice to make a symbolic link so the path
    /usr/cygnus/beta-941019 works regardless which host. The actual
    binaries are in /usr/cygnus/beta-941019/$host/bin, where host is
    the configuration string for this machine.

Downloading
-----------
    To download type the "U" command to the ROM monitor. This will
    load to the address as specified in the srecord. This address is
    0x100000. 

To compile
----------
    Use these arguments on the command line for either the linker or
    the compiler:

        -Tw89k.ld -Ttext 100000

To execute
----------
    Type a "g = 100000" at thr ROM monitor after downloading to the
    target. After downloading, PC will be set to the correct address,
    but this command will *always* restart the execution from the
    beginning. 
    
To debug
--------
    To connect GDB to the target, use the "target w89k [devicename]".

Downloading
-----------
    To download, type "r 0" to the ROM monitor. The 0 is cause the
    monitor wants to offset the address in the srecord to 0x40000. The
    problem is that it doesn't relocate data right. So, we set the
    address for .text and .data to 0x40000, and we don't want any
    offset.

To compile
----------
    Use these arguments on the command line for either the linker or
    the compiler:

        -Top50n.ld -Ttext 40000

 To execute
----------
    Type a "g 40000" at thr ROM monitor after downloading to the
    target. After downloading, PC will be set to the correct address,
    but this command will *always* restart the execution from the
    beginning
    
To debug
--------
    To connect GDB to the target, use the "target op50n [devicename]".
