2009-06-06move src/runtime -> src/lib/runtime;Russ Cox1-858/+0
only automatic g4 mv here. R=r OCL=30002 CL=30007
2009-06-0232-bit fixes in lessstack.Russ Cox1-13/+12
avoid tight coupling between deferreturn and jmpdefer. before, jmpdefer knew the exact frame size of deferreturn in order to pop it off the stack. now, deferreturn passes jmpdefer a pointer to the frame above it explicitly. that avoids a magic constant and should be less fragile.

2009-04-01fix runtime stack overflow bug that gri ran into:Russ Cox1-152/+208
160 - 75 was just barely not enough for deferproc + morestack. added enum names and bumped to 256 - 128. added explanation. changed a few mal() (garbage-collected) to malloc()/free() (manually collected). R=ken OCL=26981 CL=26981

2009-01-28Use explicit allspan list instead ofRuss Cox1-4/+4
trying to find all the places where spans might be recorded. Free can cascade into complicated span manipulations that move them from list to list; the old code had the possibility of accidentally processing a span twice or jumping to a different list, causing an infinite loop.

2008-12-05add support for ref counts to memory allocator.Russ Cox1-3/+40
mark and sweep, stop the world garbage collector (intermediate step in the way to ref counting). can run pretty with an explicit gc after each file. R=r DELTA=502 (346 added, 143 deleted, 13 changed) OCL=20630 CL=20635
2008-12-04add stub routines stackalloc() and stackfree().Russ Cox1-7/+30
run oldstack on g0's stack, just like newstack does, so that oldstack can free the old stack. R=r DELTA=53 (44 added, 0 deleted, 9 changed) OCL=20404 CL=20433
2008-11-25change meaning of $GOMAXPROCS to number of cpus to use,Russ Cox1-62/+153
not number of threads. can still starve all the other threads, but only by looping, not by waiting in a system call. fix darwin syscall.Syscall6 bug. fix chanclient bug. delete $GOMAXPROCS from network tests. add stripped down printf, sys.printhex to runtime.

2008-08-05* comment, clean up schedulerRuss Cox1-175/+285
* rewrite lock implementation to be correct (tip: never assume that an algorithm you found in a linux man page is correct.) * delete unneeded void* arg from clone fn * replace Rendez with Note * comment mal better * use 6c -w, fix warnings * mark all assembly functions 7 R=r DELTA=828 (338 added, 221 deleted, 269 changed) OCL=13884 CL=13886
2008-08-04first cut at multithreading. works on Linux.Russ Cox1-25/+198
* kick off new os procs (machs) as needed * add sys·sleep for testing * add Lock, Rendez * properly lock mal, sys·newproc, scheduler * linux syscall arg #4 is in R10, not CX * chans are not multithread-safe yet * multithreading disabled by default; set $gomaxprocs=2 (or 1000) to turn it on This should build on OS X but may not. Rob and I will fix soon after submitting. TBR=r OCL=13784 CL=13842
