2009-10-15rename sys functions to runtime,Russ Cox1-93/+0
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

that have not changed since I applied gofmt. R=gri DELTA=456 (77 added, 3 deleted, 376 changed) OCL=35378 CL=35383
2009-09-08pass Type* to makechan and makemap so thatRuss Cox1-4/+4
they can get the official alignment out of there instead of guessing. R=ken OCL=34450 CL=34450

R=ken OCL=32576 CL=32580
2009-07-17another step toward eliminating forward declarations.Russ Cox1-1/+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
2009-07-07runtime: use new reflect data structures (CL 31107)Russ Cox1-11/+11

2009-05-268g: 64-bit arithmetic and assorted bug fixes;Russ Cox1-0/+6
can run 64-bit sieve and powser. interfaces are limping along. next hurdle is floating point. R=ken OCL=29418 CL=29423

R=ken OCL=29209 CL=29216
2009-05-20stricter interface conversion rule: i.(T)Russ Cox1-0/+1
must have non-nil i. R=ken OCL=29136 CL=29136
2009-05-20change representation of interface values.Russ Cox1-1/+10
this is not a user-visible change. before, all interface values were struct Itype { Sigt *type; Sigi *inter; void *method[n]; } struct Iface { void *addr; Itype *itype; } the itype is basically a vtable, but it's unnecessary if the static type is interface{ }. for interface values with static type empty, the new representation is struct Eface { void *addr; Sigt *type; } this complicates the code somewhat, but it reduces the number of Itypes that have to be computed and cached, it opens up opportunities to avoid function calls in a few common cases, and it will make it possible to lay out interface{} values at compile time, which i think i'll need for the new reflection.

2009-05-056g tweaksRuss Cox1-1/+0
* byteastring is no longer used * do not generate ODCL, OAS for globals (wasn't generating any code but might save one or two init functions) * do not call self from Init function R=ken OCL=28309 CL=28309

2008-12-19compiler changes for *chan -> chan; *map -> map; new(T) -> new(*T)Russ Cox1-14/+14
