for that file to not be built with profiling. This makes it reasonable to
use pthread_{set,get}specific() to implement thread-safe profiline call counts.
When disabling cancellation, clear the pt_cancel flag if it was set
and note the cancellation request with PT_FLAG_CS_PENDING. This avoids
a problem where a cancellation request entered but not acted upon before
pthread_setcanclstate(PTHREAD_CANCEL_DISABLE) is called would still be
aceted upon before cancellation was re-enabled.
pthread_attr_t objects, although most of the properties being set don't really
affect threads yet:
pthread_attr_{get,set}guardsize()
pthread_attr_{get,set}inheritsched()
pthread_attr_{get,set}scope()
pthread_attr_{get,set}stack()
pthread_attr_setstack{size,addr}()
Remove some useless assertions and error checks in the existing pthread_attr()
routines.
Implement pthread_attr_get_np(), to examine the attributes of an existing
thread. Idea and interface from FreeBSD.
Change PTHREAD_ERRORMODE environment variable to PTHREAD_DIAGASSERT, and
make it behave like libc's LIBC_DIAGASSERT. The way to disable error-checking
and aborting is now "PTHREAD_DIAGASSERT=AEL", rather than
"PTHREAD_ERRORMODE=ignore".
1. add new pthread__abort() and change pthread_assert(0) to it.
2. put constcond in the right place (in the macro).
3. no space after pthread__assert macro.

pthread_create()), so that there's no opportunity for a fork() to
clear the per-process timer.

opposed to internal errors. The setting of the PTHREAD_ERRORMODE
environment variable determines the runtime behavior. Valid settings
are "ignore", "abort", and "print". The default is currently "abort".

* pthread_attr_setname_np()

In addition to being query'able by the application (for log messages, etc.),
it is intended that these names can show up in the debugger.

PT_FLAG_CS_DISABLED in pt_flags.
Prevents cancellation cleanup handlers from thinking that they've been
canceled and exiting mid-handler. Problem spotted by Matt Thomas.
* thr_create() (stub in libc aborts)
* thr_exit() (stub in libc calls exit())
* thr_yield() (stub in libc does nothing)
Also make the libc thr_self() stub not abort.
XXX Should we add thrattr_*() stubs for setting the detach-state?
- remove argument variable names since they pollute the namespace
- add mock implementation of the missing stack functions
XXX: we need to do this right [i.e. actually get and set sizes and addresses]
but the current stack setup makes this a bit complicated.
