* Use the recently exposed fs/gs set functions when compiling libthr topeter2004-11-061-0/+12
| | | | | | | run as a 32 bit support library for an amd64 kernel. 32 bit consumers of libthr have zero chance of running on an amd64 kernel since we don't implement the i386_set_ldt() family of functions. Note that this commit doesn't make it actually work, it just removes one more obstacle.

* Make NULL a (void*)0 whereever possible, and fix the warnings(-Werror)markm2004-03-051-1/+1
| | | | | | | | | | | | | | | that this provokes. "Wherever possible" means "In the kernel OR NOT C++" (implying C). There are places where (void *) pointers are not valid, such as for function pointers, but in the special case of (void *)0, agreement settles on it being OK. Most of the fixes were NULL where an integer zero was needed; many of the fixes were NULL where ascii <nul> ('\0') was needed, and a few were just "other". Tested on: i386 sparc64

* Add two functions: _spinlock_pthread() and _spinunlock_pthread()mtm2003-05-231-2/+4
| | | | | | | | | | that take the address of a struct pthread as their first argument. _spin[un]lock() just become wrappers arround these two functions. These new functions are for use in situations where curthread can't be used. One example is _thread_retire(), where we invalidate the array index curthread uses to get its pointer..

| | | | | | | | | | | | in thr_private.h o Lock down the ldt_entries array and ldt_free, which points to the next free slot. As noted in the comments, it's necessary to special case the initial_thread because %gs is not setup for it yet. This is ok because that early in the program there won't be any reentrancy issues anyways. Approved by: re/blanket libthr
* Fix a null dereference leading to a core dump whenmtm2003-05-061-1/+4

* Add support for ia64.marcel2003-04-202-0/+64
| | | | | | | | | | | Note that the tp register (r13) is reserved as the TLS pointer in the same way that that gp register (r1) is reserved as the global pointer. This implementation uses the tp register to point to the thread structure used by the threads implementation. This is not in violation with the runtime specification provided the TLS is a fixed distance from the thread structure. This is only an issue when code used the __thread keyword to create TLS. This is not supported at the moment.
