2009-10-038c, 8l dynamic loading support.Russ Cox13-103/+179
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.

2009-09-22changes to accommodate nacl:Russ Cox15-6/+358
* change ldt0setup to set GS itself; nacl won't let us do it. * change breakpoint to INT $3 so 8l can translate to HLT for nacl. * panic if closure is needed on nacl. * do not try to access symbol table on nacl. * mmap in 64kB chunks. nacl support: * system calls, threading, locks.

2009-09-21convert 386 to use %gs instead of %fs for extern register.Russ Cox4-35/+26

2009-08-20FFI step 2: can ask for libc.so.6.Russ Cox1-1/+2
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.

2009-07-28make every func literal expression allocate,Russ Cox2-61/+66
so that == on func means that the functions originated in the same execution of a func literal or definition. before, there was an inconsistency: func() {x++} != func() {x++} but func() {} == func() {} this CL makes the second case != too, just like make(map[int]int) != make(map[int]int) R=r DELTA=202 (71 added, 62 deleted, 69 changed) OCL=32393 CL=32398

2009-07-21runtime: fix init scheduling bug.Russ Cox1-0/+8
if there is a goroutine waiting to run and the init goroutine enters a system call, entersyscall was trying to kick off a new scheduler for the other goroutine, causing a panic (new goroutines can't run until main.main). R=r DELTA=32 (32 added, 0 deleted, 0 changed) OCL=31982 CL=31982
2009-07-17another step toward eliminating forward declarations.Russ Cox1-7/+0
introduce NodeList* type in compiler to replace OLIST. this clarifies where lists can and cannot occur. list append and concatenation are now cheap. the _r rules are gone from yacc. rev and unrev are gone. no more lists of lists. the representation of assignments is a bit clunkier. split into OAS (1=1) and OAS2 (2 or more on one side). delete dead chanrecv3 code. delay construction of func types. R=ken OCL=31745 CL=31762
