[Qt-interest] [Qt4] ELF visibility with SunStudio compiler

[Darin Broady]

If anyone current is using the SunStudio compiler suite to compile Qt, then the following may be of interest to you.

I have created a merge request that allows for Qt to be built with ELF visibility with the SunStudio compilers (8 or later) using the compiler option -xldscope, and the code attributes __global/__hidden.  It requires patching 5 files, all relatively simple if you wish to it manually.  This will mostly match up the SunStudio compilers with how GCC 4+ implements ELF visibility.  The only part not matched up is GCC's -fvisibility-inlines-hidden option, which has no equilvalent in SunStudio.

I have tested the examples that come with Qt to make sure that everything works as expected, and I have found no problems thus far.  If you find an issue with this patch, please let me know so that I can update the merge request.  Thanks.

The merge request is at:   http://qt.gitorious.org/qt/qt/merge_requests/433
