missing break after error. dot symbol bug fix: leave sym alone (was incorrect for inserted cross-package dots). R=ken OCL=31234 CL=31236
2009-07-06allow conversion to interface typeRuss Cox1-1/+8
when implicit assignment would have been okay. R=ken OCL=31225 CL=31227

2009-06-23fix a 6g crash after type errors.Russ Cox1-5/+13
do not bother warning about marks left on stack after syntax errors. leave OCONV nodes in tree to avoid type errors arising from multiple walks. R=ken OCL=30639 CL=30662

2009-05-21stricter rules for assignment.Russ Cox1-1/+46
when assigning a multifield object (structs or arrays of structs) they must not contain any fields that could not be assigned individually. R=ken OCL=29192 CL=29194
2009-05-21added key:val extension toKen Thompson1-28/+84
structure and array literals R=r OCL=29190 CL=29190
2009-05-20stricter interface conversion rule: i.(T)Russ Cox1-1/+6
must have non-nil i. R=ken OCL=29136 CL=29136
2009-05-20ifaceop was being called with integersRuss Cox1-14/+29
that came from two different enums. spilt into ifacecvt and ifaceop depending on which enum the argument is. R=ken OCL=29122 CL=29122
2009-05-20change representation of interface values.Russ Cox1-16/+101
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. R=ken OCL=28701 CL=29121
2009-05-20fix implicit star for range on *map, *[].Russ Cox1-7/+11
do not update lineno from ONAME nodes, because they have declaration lineno not use. show actual name in top-level statement error. before runtime.a:7: x.go:5: walkstate: NAME not a top level statement after x.go:14: walkstate: runtime.Goexit not a top level statement R=ken OCL=29113 CL=29116

store only the original import path string (+ .a) if 6g resolves it to an archive file. let 6l re-resolve the .a at link time. this lets libraries build against an archive in the current directory but get used against an installed archive. R=r OCL=27244 CL=27244
