Usage: $0 [ --build | --build-only | --run-built ] [ <make options> ]
 
 paul@456     59 
 
 paul@456     60 
Run the toolchain over all tests in the tests directory.
 
 paul@323     61 
 
 paul@456     62 
If --build is specified, the generated program code will be compiled and run,
 
 paul@456     63 
with the results collected in the _results directory.
 
 paul@456     64 
 
 paul@456     65 
If --build-only is specified, the generated programs themselves will be
 
 paul@456     66 
collected in the _results directory, each taking their name from that of the
 
 paul@456     67 
main program file used as input.
 
 paul@456     68 
 
 paul@456     69 
If --run-built is specified, any generated programs in the _results directory
 
 paul@456     70 
will be run and their output collected in the _results directory.
 
 paul@323     71 
 
 paul@456     72 
By using --build-only on one system, copying the _results directory to another
 
 paul@456     73 
system, and then running this script with the --run-built option on the other
 
 paul@456     74 
system, it becomes possible to test the toolchain output on the other system
 
 paul@456     75 
without needing to actually use the toolchain on that system. This permits the
 
 paul@456     76 
testing of cross-compiled programs.
 
 paul@456     77 
 
 paul@456     78 
For example, to build on one system but not run the generated programs:
 
 paul@456     79 
 
 paul@456     80 
ARCH=mipsel-linux-gnu $PROGNAME --build-only
 
 paul@455     81 
 
 paul@456     82 
And to run the generated programs on another system:
 
 paul@456     83 
 
 paul@456     84 
$PROGNAME --run-built
 
 paul@456     85 
 
 paul@456     86 
Of course, this script will need to be copied to the target system if it is not
 
 paul@456     87 
already available there.
 
 paul@456     88 
 
 paul@456     89 
Build and output logs are stored in the _results directory with the .build and
 
 paul@456     90 
.out suffixes employed respectively, one of each kind for each generated
 
 paul@456     91 
program.
 
 paul@918     92 
 
 paul@918     93 
The make options can be used to specify things like the number of processes
 
 paul@918     94 
employed to perform a build of each program. For example:
 
 paul@918     95 
 
 paul@918     96 
$PROGNAME --build -j8
 
 paul@456     97
