This has been discussed before, not that long ago on one of the Valgrind lists, but I couldn't find it in the Gmane index. In short, apparently an incomplete but reasonably usable x86/MacOSX port has been written by Greg Parker, an Apple employee. We would love to have this port become part of Valgrind, as it would broaden Valgrind's audience greatly (more than any other port except a Windows port, which would be technically difficult, but some people have been making excellent progress lately with Wine). AFAICT the obstacles to Greg's code being made public are more legal (to do with Apple releasing open source code) than technical. Although Greg earlier suggested that a post-Leopard release was possible, that hasn't eventuated so it's unclear if/when it will be made public. If anyone has more recent/better information than I do please feel free to correct me! Nick |

I Googled but couldn't find it. Is it a C++ parser? In the comments on your post there are complaints that the Valgrind docs encourage people to write coverage tools but it's been done several times before. First, I believe this is no longer in the docs -- at least, I just looked and couldn't find it in the section linked to or any other sections. Second, any suggestions you have for improvements are much more likely to be addressed if you report them to this list or Bugzilla rather than writing them in your blog. Nick |
