                              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 jeremybenn
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 82 jeremybenn
 
12 90 jeremybenn
Tests are provided for the standalone simulator (or1ksim) and for the library
13
(libsim.a).
14 82 jeremybenn
 
15 122 jeremybenn
At the time of writing a total of 1,829 tests compile, run and pass. That
16
figure is broken down into 1,565 tests of the standalone simulator and 264
17 116 jeremybenn
tests of the library
18 90 jeremybenn
 
19 82 jeremybenn
Configuration and make files are provided for further test programs. These
20
come in three categories.
21
- Tests which compile correctly, but will not run to completion.
22
- Tests which compile, but will not run at all.
23
- Tests which will not compile correctly.
24
 
25
File Organization
26
=================
27
 
28 90 jeremybenn
Each test program has its own directory under test-code (for native tests,
29
typically of the library) or test-code-or1k (for OpenRISC code, which must use
30
the OpenRISC tool chain). This builds the test program. If necessary it copies
31
data files to the main build/testsuite directory.
32 82 jeremybenn
 
33 90 jeremybenn
Each test then has a DejaGNU expect script in or1ksim.tests (for standalone
34
tests) and libsim.tests (for library tests), which loads and runs the
35
test. Support script procedures are in lib/or1ksim.exp and lib/libsim.exp.

37
Libraries
38
=========
39
 
40
Within the test-code there are several libraries:
41
 
42
support:    A minimal C library.
43
except:     Exception handling and startup code.
44
mc-common:  A library to support the memory controller tests.
45
 
46

99
===============================================
100
 
101 93 jeremybenn
The following tests of standalone Or1ksim rely on VAPI in Or1ksim, so need a
102
client to provide test data over TCP/IP.

========================================
109
 
110 93 jeremybenn
These tests of standalone Or1ksim (which are built by the make file), do not
111
appear to run at all. The problem is in the linker script and/or the
