in struct _machdep_state from libpthread.
The offset is hardcoded in boehm-gc because it's a private struct so we
cannot use offsetof(). This will probably not change soon again but I am
writing this as a note for people who will run into the same problem in
the future.
All the regression tests are passing now and mono builds fine too.
Thanks to kurt@ for pointers.
and adjust boehm-gc to deal with any number of holes that may appear
between __data_start and _end. (requires -current binutils)
- work-around libpthread bugs that prevent sigsuspend() from working
in a signal handler by using pthread_suspend_np() + an arch/libpthread
specific offset to obtain the suspended thread's stack pointer.
thanks to sthen@ and jasper@ for access to other arches. discussed
with todd@
Most work done by kurt@, who got bleeding eyes and has been trapped
into pthread issues because some of us (me and Stuart Henderson)
were slopyy and applied some patches only partial. A big sorry to
kurt@ for this waste of time!
Tested by many. Intermediate ok's (IIRC) from kurt@, naddy@ and todd@.
