2009-06-17runtime: stack growth adjustments, cleanupRuss Cox1-43/+90
* keep coherent SP/PC in gobuf (i.e., SP that would be in use at that PC) * gogocall replaces setspgoto, should work better in presence of link registers * delete unused system calls only amd64; 386 is now broken R=r DELTA=548 (183 added, 183 deleted, 182 changed) OCL=30381 CL=30442
2009-06-16grab bag of changes aimed at getting stack splitting to work:Kai Backman1-0/+5
- morestack support for 5l and arm runtime - argsize support in 5c, 5l, ar and nm. assembly code from 5a will break in interesting ways unless NOSPLIT is specified - explicit cond execution constants - fix 5l output to use %d instead of %ld so that negative values show. - added a lot of code to arm/asm.s. runtime entry code almost working currently aborts at gogo not implemented R=rsc APPROVED=rsc DELTA=305 (125 added, 29 deleted, 151 changed) OCL=30246 CL=30347

* heuristic to go farther during stack traces. * significantly improved Linux thread handing. acid: * update to new libmach interface. prof: * use new libmach interface. * multiple thread support (derived from Rob's copy). * first steps toward pprof-like graphs: keep counters indexed by pc,callerpc pairs.

2008-08-03make 6a, 6c, 6g, 6l, libmach_amd64 build on 64-bit gcc.Russ Cox11-147/+147
these guys really really want long to be 32-bits, so ,s/long/int32/ (and then manual fixup). still passes all tests. (i started out looking for just those longs that needed to be int32 instead, and it was just too hard to track them down one by one.) the longs were rare enough that i don't think it will cause integration problems.
