Andy Wingo cd9d95d760 fixes so that typing asdfadfasff in the repl doesn't error ... Before: > ,c (set! x 3) 0 (make-int8 3) ;; 3 2 (link "x") 5 (variable-set) > ,c (define x 3) 0 (make-int8 3) ;; 3 2 (link "x") 5 (variable-set) After: > ,c (define x 3) 0 (make-int8 3) ;; 3 2 (define "x") 5 (variable-set) * src/vm_loader.c (link): `link' now errors if the variable is undefined. This corresponds with desired behavior, for both `ref' and `set' operations, for scheme. It's not what elisp wants, though. Perhaps elisp linking needs another instruction. (define): New instruction, the same as calling scm_define(), basically. * module/language/scheme/translate.scm (trans-pair): Don't try to look up an existing variable definition when translating `define'; instead use the special-purpose lookup from ghil.scm's `ghil-define'. * module/system/il/compile.scm (codegen): Compile to a different kind of variable access from `set!', specifically via passing 'define as the op to `make-glil-var'. * module/system/il/ghil.scm (ghil-lookup): Don't add to the module table when compiling variable sets via `set!'. (ghil-define): New procedure, for looking up variables for `define'. * module/system/vm/assemble.scm (<vdefine>): New record: a new instruction type. (codegen): Compile `define' module vars into <vdefine>. (dump-object!): <vdefine> == `define'.		2008-05-12 00:22:36 +02:00
