Modified Files:
basesrc/lib/libpthread/arch/i386 [nathanw_sa]: pthread_switch.S
Log Message:
Substantial rework:
- Make pthread__switch() just a plain switch, and move the
switch-to-next code to pthread__switch_away. Saves a stack switch,
test, and branch in the pthread_switch case, a _getcontext_u() and
associated stack frobbing in the switch_away case, and several
points of sanity.
- Remove a poorly-thought-out ucontext-dodge in STACK_SWITCH.
- Fill in PT_SWITCHTO and PT_SWITCHTOUC in the new_preempt path as
well as the old_preempt path in pthread__locked_switch() and
pthread__upcall_switch().
