2010-06-08gc: new typechecking rulesRuss Cox1-12/+16
* Code for assignment, conversions now mirrors spec. * Changed some snprint -> smprint. * Renamed runtime functions to separate interface conversions from type assertions: convT2I, assertI2T, etc. * Correct checking of \U sequences. Fixes issue 840. Fixes issue 830. Fixes issue 778. R=ken2 CC=golang-dev http://codereview.appspot.com/1303042

2010-03-31gc: implement panic and recoverRuss Cox1-1/+1
R=ken2, r, ken3 CC=golang-dev http://codereview.appspot.com/831042
2010-03-30gc: add panic and recover (still unimplemented in runtime)Russ Cox1-1/+2
main semantic change is to enforce single argument to panic. runtime: change to 1-argument panic. use String method on argument if it has one. R=ken2, r CC=golang-dev http://codereview.appspot.com/812043
2010-03-09identical complex implementationKen Thompson1-0/+1
for 6g and 8g. can also be used for 5g. 5g is still a stub. R=rsc CC=golang-dev http://codereview.appspot.com/362041

2010-01-22eliminate the package global name space assumption in object filesRuss Cox1-84/+84
5g/6g/8g: add import statements to export metadata, mapping package path to package name. recognize "" as the path of the package in export metadata. use "" as the path of the package in object symbol names. 5c/6c/8c, 5a/6a/8a: rewrite leading . to "". so that ·Sin means Sin in this package. 5l/6l/8l: rewrite "" in symbol names as object files are read. gotest: handle new symbol names. gopack: handle new import lines in export metadata. Collectively, these changes eliminate the assumption of a global name space in the object file formats. Higher level pieces such as reflect and the computation of type hashes still depend on the assumption; we're not done yet.

2010-01-19cleanup toward eliminating package global name spaceRuss Cox1-84/+84
* 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).

2009-10-15rename sys functions to runtime,Russ Cox1-75/+75
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

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.

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. R=ken OCL=28701 CL=29121
2009-05-12no need for compiler to hard-code definition of runtime.Russ Cox1-8/+0

2009-03-05new approach for generating sysimport.cRuss Cox1-0/+72
(renamed to avoid any conflict with old p4 copies). this approach doesn't require auto-generating files also kept in p4, so it should be easier on go users who don't sync very often. this approach will be more work for go developers: builtin.c needs to be copied to builtin.c.boot in p4 as new functions are added. mkbuiltin does this for certain $USERs to help us remember.
