| # glibc-2.X specific |
| # These are generic cover-alls which catch a lot of stuff |
| # in various combinations of ld, libc and libpthread |
| # |
| # Note this is heavyhanded and not very clever: |
| # |
| # - suppress anything that has its top frame in ld.so |
| # That's fine, since it's mostly dynamic linking stuff, |
| # which has various deliberate (harmless) races |
| # |
| # - suppress anything that has its top frame in libc.so. |
| # This really isn't clever, since it could hide some |
| # legitimate races. But the problem is, if we don't do |
| # this, then loads of errors to do with stdio are reported, because |
| # H fails to see glibc's internal locking/unlocking of FILE*s |
| # as required by POSIX. A better solution is needed. |

| # These are very ugly. They are needed to suppress errors inside (eg) |
| # NPTL's pthread_cond_signal. Why only one stack frame -- at least we |
| # should see the wrapper calling the real functions, right? |
| # Unfortunately, no: the real functions are handwritten assembly (in |
| # the glibc-2.5 sources) and does not create a proper stack frame. |
| # Therefore it's only one level of unwinding before we're back out in |
| # user code rather than the 2 levels you'd expect. |
