Helper Makefile for testing gcc toolchains using the gcc-testsuite

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

Requirements

------------

* DejaGnu 'runtest' v1.4.4+

* Make v3.81+

* wget

Configuration

-------------

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

Alternatively, override configuration variables on the command line.

Available config variables:

DG_GCC_VERSION

DG_GCC_URL

DG_TOOLNAME

DG_TARGET

DG_TARGET_HOSTNAME

DG_TARGET_USERNAME

DG_C_TESTS

DG_CPP_TESTS

DG_TOOLCHAIN_DIR

DG_SRC_DIR

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)

scp ~/.ssh/id_rsa.pub <username>@<target IP>:~/

On target do:

cd ~

mkdir .ssh

cat id_rsa.pub >> .ssh/authorized_keys

rm id_rsa.pub

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.
