GNU toolchain testing
Introduction
This page captures the results of testing the GNU tool chain. For any test run, it is likely a number of tests will be marked as "FAIL", "XFAIL", "UNRESOLVED", "UNTESTED" or "UNSUPPORTED". It is important that the reasons for such results are recorded.
Unless otherwise indicated, the tests are applied to the SVN version of the tool on the date of the test. Where a C library has been used, it is Newlib 1.18.0 from SVN unless otherwise indicated. Where a model target is needed, it is the latest version of Or1ksim from SVN unless otherwise indicated.

| unordered .debug_info references to .debug_ranges | This test, which confusingly duplicates the name of the previous test (a binutils bug), is only for execution on ia64 targets. |

Check --gc-sections on tls variable Check --gc-section Check --gc-section/-q Check --gc-section/-r/-e Check --gc-section/-r/-u |
--gc-sections is not actually supported for the OpenRISC 1000, let the linker --help reports that it is, so these tests are run |

gcc.dg/uninit-13.c unconditional (test for warnings, line 8) gcc.dg/uninit-13.c (test for excess errors) |
This test is expected to generate a warning, but does so int he wrong place. |
| gcc.dg/special/gcsec-1.c (test for excess errors) | This is not really a compiler bug. It is a consequence of ld not supporting --gc-sections. |
| gcc.dg/tree-ssa/reassoc-13.c scan-tree-dump optimized "return a_..D.;" | This is a deep problem within the tree optimization. Since this is before the detailed architecture becomes invovled, it likely is an underlying generic GCC problem. It is not believed that this will cause significant problems, possibly just some cases where code optimization is not achieved. |
XFAIL test cases
These are generally tests that the compiler correctly rejects operations it cannot support.
UNSUPPORTED test cases
These tests come into a number of categories:
- Tests for specific architectures.
- Tests for native compilers.
- Tests for gcov, which require filesystem support (not available in OR32 newlib).

C++ support for OpenRISC is still incomplete, and currently uses only static linking.
FAIL test cases
Failures fall into a number of categories.
- Incompatible definition of wchar in newlib (the main cause of failure).
- Lack of newlib support for files and gettimeofday.
- Insufficient memory to run the test.
XPASS test case
| Test Name | Comment |
|---|---|
| 27_io/objects/wchar_t/12048-5.cc execution test | The incompatible definition of wchar is thought to have allowed this test to pass, when it should have failed. |

The large increase in failures follows the introduction of DWARF2 output as the default for GCC.
