Helper Makefile for testing gcc toolchains using the gcc-testsuite
==================================================================

Requirements
------------

* DejaGnu 'runtest' v1.4.4+
* Make v3.81+


Configuration
-------------

Edit default.cfg to reflect your toolchain and target configuration.

Alternatively, override configuration variables on the command line.

Available config variables:

DG_TOOLNAME
  The name of the tool you want to test.
  Currently supported: gcc or g++
  Default: gcc

DG_TARGET_HOSTNAME
  The hostname or IP of the machine to execute run-tests
  Default: 127.0.0.1

DG_TARGET_USERNAME
  Execute the run-test as this user on DG_TARGET_HOSTNAME
  Default: root

DG_C_TESTS
DG_CPP_TESTS
  The C/C++ tests you want to check
  Default: (empty, means all tests)


Run examples
------------

The first two examples require a networked target with ssh access and automatic
ssh login (see section below). Target SW should be compiled with the toolchain 
to be tested.

Run default gcc compile/execution tests:
$ make DG_TOOLNAME=gcc DG_TARGET_HOSTNAME=192.168.17.93 DG_TARGET_USERNAME=root

Run default g++ compile/execution tests:
$ make DG_TOOLNAME=g++ DG_TARGET_HOSTNAME=192.168.17.93 DG_TARGET_USERNAME=root

Run selected gcc compile only tests (no target required):
$ make DG_TOOLNAME=gcc DG_C_TESTS="compile.exp noncompile.exp" 


SSH automatic login configuration example
-----------------------------------------

On host do: 
ssh-keygen -t rsa (then simply press enter thru all steps)
ssh-copy-id -i ~/.ssh/id_rsa.pub <username>@<target IP>

Now automatic ssh login should work - test by doing a simple ssh session to target.

Note: The procedure might be slightly different for your particular target.


Getting rid of the test-suite
-----------------------------

If you no longer have a need for the test-suite, then you can remove it altogether
from your toolchain. Just delete the test-suite/ dub-dir.
