                  OpenRISC Unified GNU Tool Chain Repository

                  ==========================================

This directory is where you will find all the source trees for the standard

GNU tool chain. The newlib library is included, since that is required for GCC

testing.

The structure mirrors that of the main Free Software Foundation repository.

Using a unified directory means that the entire tool chain can be built in a

single pass. The script "bld.sh" will build a unified source tree in the a

directory (default name "srcw") and then configure, build, check and install

all the tools using a separate build directory (default "bld-or32"). The

default install directory is "/opt/or32-elf-new").

Use "./bld.sh --help" to check the options available, which includes options

to change all the default directories, omit building newlib and to control

whichphases of the build process (linking, configuring, building, checking and

installing) are run.

By default the tests (which require DejaGnu to be installed) are *not* run.

Note in particular that the script requires a version of Or1ksim built from

SVN (not Or1ksim 0.4.0 release) and that the --or1ksim parameter should be

used to point to the directory where or1ksim is installed (default

/opt/or1ksim-new).

Any questions should be posted on the OpenRISC forum at

opencores.org/forum,OpenRISC.
