2010-04-275l, 6l, 8l, runtime: make -s binaries workRuss Cox1-2/+22
5l, 6l, 8l: change ELF header so that strip doesn't destroy binary Fixes issue 261. R=iant, r CC=golang-dev http://codereview.appspot.com/994044
2010-01-19cleanup toward eliminating package global name spaceRuss Cox1-11/+11
* switch to real dot (.) instead of center dot (·) everywhere in object files. before it was half and half depending on where in the name it appeared. * in 6c/6a/etc identifiers, · can still be used but turns into . immediately. * in export metadata, replace package identifiers with quoted strings (still package names, not paths). R=ken2, r CC=golang-dev http://codereview.appspot.com/190076
2009-10-15rename sys functions to runtime,Russ Cox1-11/+11
because they are in package runtime. another step to enforcing package boundaries. R=r DELTA=732 (114 added, 93 deleted, 525 changed) OCL=35811 CL=35824
2009-10-12stack overflow debugging and fix.Russ Cox1-6/+44
* in 6l, -K already meant check for stack underflow. add -KK to mean double-check stack overflows even in nosplit functions. * comment out print locks; they deadlock too easily but are still useful to put back for special occasions. * let runcgo assembly switch to scheduler stack without involving scheduler directly. because runcgo gets called from matchmg, it is too hard to keep it from being called on other stacks.

2009-10-038c, 8l dynamic loading support.Russ Cox1-2/+8
better mach binaries. cgo working on darwin+linux amd64+386. eliminated context switches - pi is 30x faster. add libcgo to build. on snow leopard: - non-cgo binaries work; all tests pass. - cgo binaries work on amd64 but not 386.

if first function in file was dead code, it was being discarded along with the file name information for that file. leave the functions in the master function list longer: let xfol take the dead code out of the code list, and let span skip the unreachable functions during output. before throw: sys·mapaccess1: key not in map panic PC=0x2e7b20 throw+0x33 /Users/rsc/go/src/pkg/runtime/runtime.c:65 throw(0x5834f, 0x0) sys·mapaccess1+0x73 /Users/rsc/go/src/pkg/runtime/hashmap.c:769 sys·mapaccess1(0x2b9bd0, 0x0) gob·*Encoder·Encode+0x16b /Users/rsc/go/src/pkg/fmt/print.go:2926 gob·*Encoder·Encode(0x2bb440, 0x0, 0x558b0, 0x0, 0x2e4be0, ...) main·walk+0x331 :1603 main·walk(0x33a480, 0x0) main·walk+0x271 :1596 main·walk(0x300640, 0x0) main·walk+0x271 :1596 main·walk(0x300520, 0x0) main·walk+0x271 :1596 main·walk(0x300240, 0x0) main·walk+0x271 :1596 main·walk(0x678f8, 0x0) main·main+0x22 :1610 main·main() after throw: sys·mapaccess1: key not in map panic PC=0x2e7b20 throw+0x33 /Users/rsc/go/src/pkg/runtime/runtime.c:65 throw(0x5834f, 0x0) sys·mapaccess1+0x73 /Users/rsc/go/src/pkg/runtime/hashmap.c:769 sys·mapaccess1(0x2b9bd0, 0x0) gob·*Encoder·Encode+0x16b /Users/rsc/go/src/pkg/gob/encoder.go:319 gob·*Encoder·Encode(0x2bb3c0, 0x0, 0x558b0, 0x0, 0x2e4be0, ...) main·walk+0x331 /Users/rsc/dir.go:121 main·walk(0x2f6ab0, 0x0) main·walk+0x271 /Users/rsc/dir.go:114 main·walk(0x301640, 0x0) main·walk+0x271 /Users/rsc/dir.go:114 main·walk(0x301520, 0x0) main·walk+0x271 /Users/rsc/dir.go:114 main·walk(0x301240, 0x0) main·walk+0x271 /Users/rsc/dir.go:114 main·walk(0x678f8, 0x0) main·main+0x22 /Users/rsc/dir.go:128 main·main() mainstart+0xe /Users/rsc/go/src/pkg/runtime/amd64/asm.s:55 mainstart() goexit /Users/rsc/go/src/pkg/runtime/proc.c:133 goexit() R=r DELTA=46 (20 added, 25 deleted, 1 changed) OCL=34094 CL=34103

2009-08-20FFI step 2: can ask for libc.so.6.Russ Cox1-0/+9
introduced explicit "data" symbol instead of etext to mark beginning of data, so that using larger alignment (i.e. 4MB like GNU loader) doesn't confuse garbage collector. split dodata into dodata and dobss in preparation for putting the dynamic data + headers in the data segment instead of stuffed at the beginning of the binary.

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

if stack is in low memory and frame size is huge, test could wrap around! fix by omitting test altogether if we know frame is big. R=gri OCL=14782 CL=14782
2008-08-03make 6a, 6c, 6g, 6l, libmach_amd64 build on 64-bit gcc.Russ Cox1-15/+15
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.
