cccf9dfce5 The field "pt_sleepuc" doesn't exist in struct pthread_st. 2003-07-05 21:27:23 +00:00

9639eeaf54 Adapt to pt_trapuc: change STACK_SWITCH to check for a value in pt_trapuc 
and use it preferentially to a value in pt_uc, clearing it once on the new
stack. Move stores into pt_uc back to before the stack switch; storing
after the stack switch opened a one-instruction race condition where an upcall
that had just started a chain could be preempted again, and would bomb when
restarted due to its pt_uc not yet having been updated. Now that pt_trapuc
is what the upcall code writes to, it is safe to store to pt_uc before
switching stacks.

Remove obsolete pt_sleepuc code.

39f9ecfa06 Oops, reordering the PT_STATE/PT_SWITCHTOUC/PT_SWITCHTO assembly 
killed a live value too soon. Fix by using a different register for
the PT_STATE immediate.

b92f152573 First bits of SH3 support. Only _context_u.S is implemented (passess 
cu[1-6] tests), the pthread_switch.S is stubbed out for now.

Code posted by Christian Groessler (cpg at aladdin dot de) to port-sh3.

aa6f5de228 STACKSPACE of 16 is too small, given the use of CALLFRAME_SIZ;

f866ba061d Two fixes: 
* In switch-away cases, write PT_SWITCHTO last (after PT_SWITCHTOUC), so
   that pthread__resolve_locks() doesn't see an empty SWITCHTOUC value. This
   also permits pthread__resolve_locks() to use the presence of PT_SWITCHTO
   as a sign that the thread has done all of its necessary chain work.

 * Make the return-point of pthread__switch global and visible, so that its
   address can be compared to the PC of a thread, again as a sign that its
   chain-work is done.

(other architectures in progress, after they get the *previous* asm fix...)

edc79413b1 Don't need to set the MSR field here; _INITCONTEXT_U_MD() takes care 
of that where necessary.
