* libguile/vm-engine.c (vm_run): Add another byte onto the bootstrap program, as the offset passed to mv-call now takes two bytes. * module/system/vm/frame.scm (bootstrap-frame?): Update for the new bootstrap length. Really we should just check for 'halt though. * libguile/vm-i-system.c (FETCH_OFFSET): New helper, used in BR(). (goto/nargs, call/nargs): Versions of goto/args and call, respectively, that take the number of arguments from a value on the top of the stack. (mv-call): Call FETCH_OFFSET to get the offset. * module/language/scheme/translate.scm (custom-transformer-table): Compile call-with-values to <ghil-mv-call>. There is some trickery because of the r4rs.scm call-with-values trampolines. * module/system/il/ghil.scm: Add <ghil-mv-call> and accessors. * module/system/il/compile.scm (codegen): Compile <ghil-mv-call>. * module/system/il/glil.scm: Add <glil-mv-call>, which needs some special assembly because of the label. Fix some typos. * module/system/vm/assemble.scm (byte-length): New helper, factored out and made more general. (codegen): Assemble mv-call, including the label. (check-length): New helper, makes sure that the addressing is consistent within the produced object code. (stack->bytes): Rewrite to be more generic -- now `br' instructions aren't the only ones jumping around in the instruction stream. * module/system/vm/conv.scm (make-byte-decoder): Return two values in the #f case. * module/system/vm/disasm.scm (disassemble-bytecode): Rewrite, because the previous implementation depended on a guile interpreter quirk: namely, that multiple values could be represented within one value, and destructured later. |
