2009-07-21make 6l produce dynamically linked binaries (although they are fully ↵Rob Pike5-56/+336
statically linked as far as go is concerned). the -d flag is now flipped; as on the mac, -d disables dynamic. much remains to be improved to move the output closer to the gcc format. R=rsc DELTA=366 (310 added, 30 deleted, 26 changed) OCL=31929 CL=31951

2009-07-20avoid strncat in formatters.Russ Cox1-94/+55
the n argument to strncat is the maximum number of bytes to read from the src, not the total size of the destination. R=ken OCL=31871 CL=31875

2009-07-17baby step: const decls can refer to futureRuss Cox10-152/+364
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 Cox16-1916/+1763
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
2009-07-16ast:Robert Griesemer3-31/+80
- renamed Program -> SourceFile - added Package node representing the AST for an entire package - added filter function to create a source file mimicking the interface of an entire package parser: - parser entry to parse entire packages - unified naming of parser entry points - factored out entry points into new file (interface.go) gofmt: - extended to accept single .go files, and package paths: gofmt file.go // formatting of a single file gofmt -x file.go // interface of a single file gofmt -x ./MyPackage // interface of a local package gofmt -x math // interface of a $GOROOT relative package Various adjustments in dependent files, documentation.

2009-07-13compilers were inconsistent aboutRuss Cox9-28/+30
whether no register argument was REGARG == 0 or REGARG < 0. use REGARG < 0 because arm needs 0 for R0. R=ken OCL=31562 CL=31566

2009-07-10cleanup in preparation for new scoping.Russ Cox7-491/+409
walkstate -> walkstmt walktype -> walkexpr; stmts moved to walkstmt walktype and friends have a final Node **init argument that can have side effects appended, making it more explicit when they do and do not happen. this replaces the old global addtop and addtotop. delete switch map and interface conversion cases (dropped from the language months ago).

so remove code from go.y. show original types in badtype; don't remove pointers. not sure why this was here but it confuses things if the bad part involves two named pointer types with different names but the same pointed-at type. R=ken OCL=31369 CL=31369
