2009-12-02gc: make 'invalid rune in string' a little less crypticRuss Cox1-1/+3
Fixes issue 371. R=ken2 http://codereview.appspot.com/164091

2009-10-15rename sys functions to runtime,Russ Cox1-2/+2
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

turn off testdclstack and "not used" errors when there are syntax errors. BUG=2181825 R=ken OCL=35606 CL=35608
2009-10-07better handling of mistaken top-level variableRuss Cox1-17/+7
references during the parsing of :=. the base problem is that when reading a,b,c,d the parser makes those refer to existing variables, which might create a few stub top-level ones for undefined names, but then if a := is the next token, we need to undo those stubs. this was causing problems in multifile packages in which one file used a := variable named rpc and the other imported a package named rpc.

2009-07-17baby step: const decls can refer to futureRuss Cox1-0/+5
consts in the same factored block const ( X = Y; Y = 2; ) R=ken OCL=31782 CL=31782
2009-07-17another step toward eliminating forward declarations.Russ Cox1-6/+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.

new flag -A enables it during mkbuiltin. avoids mysterious errors in programs that refer to any accidentally. R=ken OCL=30763 CL=30763
2009-06-18better diagnostics for eof in a string.Ken Thompson1-6/+16
this assumes that embedded newlines are legal in back-quote strings. R=r OCL=30502 CL=30502
2009-06-06implement optional semicolons with help from the lexer,Russ Cox1-2/+42

2009-06-06gc: grammar cleanup:Russ Cox1-101/+154
* no longer distinguishes const, var, type, package names. * all the predefined names are not tokens anymore. R=ken OCL=29326 CL=29985
2009-06-05more build refinements:Russ Cox1-4/+6
* use new Make.$GOARCH files in gobuild. * rename 6ar to arch-generic gopack. * place objects in $GOROOT/pkg/$GOOS_$GOARCH (makes cross-compiling easier, and no one ever types these paths by hand anyway). R=r DELTA=29 (6 added, 8 deleted, 15 changed) OCL=29923 CL=29967

2009-05-066g: generate string data as individual symbols,Russ Cox1-3/+0
so that 6l can discard strings used by dead code. also, for short strings, generate DUPOK global symbols so that references to, say, "%s: %s" in multiple files result in only a single symbol. R=ken OCL=28361 CL=28361

R=r OCL=27293 CL=27293
2009-04-08yet another attempt at auto-linkingRuss Cox1-14/+21
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
2009-04-02use _f007·filename for func literals.Russ Cox1-2/+10
this avoids problems people have run into with multiple closures in the same package. when preparing filename, only cut off .go, not .anything. this fixes a bug tgs ran into with foo.pb.go and foo.go in the same package. also turn bad identifier chars from filename into underscores: a-b.pb.go => a_b_pb R=ken OCL=27050 CL=27050
2009-04-02use separate lex buf for better errors:Russ Cox1-12/+12

in favor of the lib9 compatibility layer. no need for two. now that mycreate is gone, .6 files are 0644 not 0755. TBR=r OCL=26679 CL=26679
2009-03-12make 6g constants behave as ken proposes. (i hope.)Russ Cox1-14/+6
