Or1ksim Test Suite
|
| 2 |
|
|
==================
|
| 3 |
|
|
|
| 4 |
|
|
This is the Or1ksim test suite, which is now integrated with the main Or1ksim
|
| 5 |
|
|
development package. It operates using a standard DejaGNU framework within the
|
| 6 |
|
|
GNU autoconf/automake/libtool structure.
|
| 7 |
|
|
|
| 8 |
90 |

A separate configuration file is needed for the OpenRISC programs used in
|
| 9 |
|
|
testing, since these use the OR1K tool chain, rather than the host tool
|
| 10 |
|
|
chain. This can be found in the "test-code-or1k" directory.
|
| 11 |

|

Tests are provided for the standalone simulator (or1ksim) and for the library
|
| 13 |
|
|
(libsim.a).
|
| 14 |
82 |
jeremybenn |
|
| 15 |
93 |
jeremybenn |
At the time of writing a total of 21 tests of the standalone simulator and 14
|
| 16 |
|
|
tests of the library compile, run and pass.
|
| 17 |

Configuration and make files are provided for further test programs. These
|
| 19 |
|
|
come in three categories.
|
| 20 |
|
|
- Tests which compile correctly, but will not run to completion.
|
| 21 |
|
|
- Tests which compile, but will not run at all.
|
| 22 |
|
|
- Tests which will not compile correctly.

File Organization
|
| 25 |
|
|
=================
|
| 26 |
|
|
|
| 27 |
90 |
jeremybenn |
Each test program has its own directory under test-code (for native tests,
|
| 28 |
|
|
typically of the library) or test-code-or1k (for OpenRISC code, which must use
|
| 29 |
|
|
the OpenRISC tool chain). This builds the test program. If necessary it copies
|
| 30 |
|
|
data files to the main build/testsuite directory.
|
| 31 |
82 |
jeremybenn |
|
| 32 |
90 |
jeremybenn |
Each test then has a DejaGNU expect script in or1ksim.tests (for standalone
|
| 33 |
|
|
tests) and libsim.tests (for library tests), which loads and runs the
|
| 34 |
|
|
test. Support script procedures are in lib/or1ksim.exp and lib/libsim.exp.

The following tests of standalone Or1ksim rely on VAPI in Or1ksim, so need a
|
| 83 |
|
|
client to provide test data over TCP/IP.

93 |

These tests of standalone Or1ksim (which are built by the make file), do not
|
| 92 |
|
|
appear to run at all. The problem is in the linker script and/or the
|
| 93 |
|
|
configuration for Or1ksim.
