2010-04-275l, 6l, 8l, runtime: make -s binaries workRuss Cox1-0/+8
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

2009-10-038c, 8l dynamic loading support.Russ Cox1-0/+11
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.

2009-09-24convert 8l to new ELF code.Russ Cox1-0/+12

2009-09-22nacl:Russ Cox1-3/+32
add jmp to constant pc. generate HLT for INT $3 do not insert NOPs between REP/REPN and subsequent instruction. allow very long time for convergence. R=ken OCL=34879 CL=34879
2009-09-21rewrite RET, indirect CALL, indirect JMP for nacl.Russ Cox1-3/+66
can JMP or CALL indirect through a register R provided the preceding instruction is AND $~31, R. R=ken OCL=34863 CL=34867

2009-09-188l: step toward native client.Russ Cox1-8/+44
- ELF header bits and addresses - do not let instructions span 32-byte boundary - align CALLs so return is to 32-byte boundary - align indirect jump targets to 32-byte boundary (only possible indirect jumps are function entries) still to do: - replace indirect jump, indirect call, and ret with nacl-approved instruction sequences - switch to GS segment for m-local storage R=ken OCL=34818 CL=34818
2009-09-18merge first pass into main loop in span calculation.Russ Cox1-45/+26
having one copy will cut nacl changes in half. R=ken OCL=34815 CL=34815
2009-08-30fix line numbers, again.Russ Cox1-0/+3
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

2009-03-31* move go-specific loader codeRuss Cox1-18/+15
into gc directory, where it gets included as ../gc/ldbody this is similar to the assemblers including ../cc/lexbody and ../cc/macbody. * hook go-specific loader code into 8l. * make current 8.out.h and 6.out.h backward compatible with plan 9's versions. i had added some constants in the middle of enums and have now moved them to the end. this keeps us from invalidating old .8 and .6 files. not sure how much it really matters, but easy to do.
