* A much better atomic lock routine.miod2009-06-011-43/+9

* Correct the _atomic_lock() asm so that gcc accepts the constraintsguenther2009-06-011-4/+4

* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-261-8/+1
| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@
* Properly align stack such that code that uses SSE2 instructions doesn't crash.kettenis2008-01-281-3/+7
| | | | ok espie@, beck@
* On hppa, function pointers may be be pointers to PLT entries. Handle thosekettenis2007-07-071-1/+12
| | | | | | | | by replicating part of $$dyncall in the code that sets up a thread's initial stack frame. Also make sure we actually reserve some space for that initial stack frame. ok miod@
* Move landisk to hardware floating point. At the moment the FPU context ismiod2007-03-022-9/+77
| | | | | | | | | | | | | | | always saved upon context switches, as FPU registers are heavily used for long long computations (don't ask). Gcc default to -m4. Credits to drahn@ otto@ and deraadt@ for feedback and help testing. Upgrade procedure if you don't want to use the damn snapshots: - build and install new kernel, reboot off it - build new gcc, do not install it yet - make includes - install new gcc - build and install lib/csu and lib/libc - make build
* pthread bits for sh; help deraadt@, ok kettenis@miod2007-02-194-3/+116

* Use correct define to detect soft fpu on arm, dont complain on lint so much.drahn2006-11-241-8/+4

* Preliminary userland bits for OpenBSD/landisk, many things coming frommiod2006-10-102-0/+64

* powerpc stack needs a bit more headroom; needed because of mmap()edotto2006-09-291-2/+2
| | | | stacks; report by Antoine Jacoutot; ok kurt@
* - due to the fninit() in _thread_machdep_save_float_state() all calls tokurt2006-04-061-5/+16
| | | | | | | | | it need to be matched with a call to _thread_machdep_restore_float_state(), so add missing one in _thread_machdep_init(). - 16-byte align fp frame - call fwait() before save and and after restoring fp state. lots of guidance and ok mickey@

* change amd64's MACHINE_ARCH from x86_64 to amd64. There are many manyderaadt2004-02-274-248/+0
| | | | | | reasons for this, quite a few of them technical, and not all of them in response to Intel's broken ia32e crud. The gcc toolchain stays at x86_64 for now.

| | | | | some `debugging features' and other optimizations (such as not saving all registers) that we can still do perhaps
