[llvm-dev] [lld] [ELF2/PPC64] test-suite status

[Hal Finkel via llvm-dev]

Hi everyone,

Here's a quick update - I ran the test suite using lld2 on my big-Endian PPC64/Linux machine (ELF v1), which is clean using the system linker, and here are the outstanding failures:

SingleSource/Regression/C/2008-01-07-LongDouble                                  | pass  0.0343   0.0737      *     0.0010    0.0080

This is due to our lack of symbol-versioning support (there was a slight ABI change affecting printf and long doubles, and we need to pick up printf@@GLIBC_2.4, not printf, for this to work).

SingleSource/UnitTests/initp1                                                    | pass  0.1512   0.2294      *     0.0011    0.0238

Support for __attribute__((init_priority(N))) incomplete I suppose.

SingleSource/Regression/C++/EH/inlined_cleanup                                   | pass  0.0527   0.0866      *     0.0015    0.0937

SingleSource/Regression/C++/EH/simple_rethrow                                    | pass  0.0341   0.0692      *     0.0013    0.0890
SingleSource/Regression/C++/EH/simple_throw                                      | pass  0.0319   0.0632      *     0.0014    0.0792
SingleSource/Regression/C++/EH/throw_rethrow_test                                | pass  0.0562   0.0977      *     0.0014    0.0995

Something with exception handling does not work (obviously).

SingleSource/UnitTests/Threads/2010-12-08-tls                                    | *     0.0406   0.0962      *     0.0001    0.0019
SingleSource/UnitTests/Threads/tls                                               | *     0.0709   0.3802      *     0.0001    0.0015

Expected failures from our lack of TLS support.

External/SPEC/CINT2006/471.omnetpp/471.omnetpp                                   | pass 74.8991  90.5139      *     1.5816    1.8107
SingleSource/UnitTests/2009-04-16-BitfieldInitialization                         | pass  0.0642   0.1969      *     0.0017    0.0098

I've not yet investigated these in detail.

The remaining ~500 tests pass as expected. In short, things are coming along quite nicely.

Thanks again everyone,
Hal
