- Remove variable _thr_scope_system, all threads are system scope. 2006-12-15T11:52:01+00:00 David Xu davidxu@FreeBSD.org 2006-12-15T11:52:01+00:00 d99f6dac14c3eb3482a788d8a181ef852a298851 - Rename _thr_smp_cpus to boolean variable _thr_is_smp. - Define CPU_SPINWAIT macro for each arch, only X86 supports it.

Rename TLS_TP_OFFSET back to TP_OFFSET. The former clashes with rtld. 2006-09-01T06:36:00+00:00 Marcel Moolenaar marcel@FreeBSD.org 2006-09-01T06:36:00+00:00 cc79b334de8a83697ac2d6225e9525cac88135e4

o  The TLS pointer (r2) points 0x7000 after the *end* of the TCB.
o  _rtld_allocate_tls() gets a pointer to the current TCB, not the
   current TLS pointer.
o  _rtld_free_tls() gets the size of the TCB structure.

 1. fast simple type mutex.
 2. __thread tls works.
 3. asynchronous cancellation works ( using signal ).
 4. thread synchronization is fully based on umtx, mainly, condition
    variable and other synchronization objects were rewritten by using
    umtx directly. those objects can be shared between processes via
    shared memory, it has to change ABI which does not happen yet.
 5. default stack size is increased to 1M on 32 bits platform, 2M for
    64 bits platform.
As the result, some mysql super-smack benchmarks show performance is
improved massivly.
