(abort): Advance the IP before capturing. The captured SP is fp - 1, not fp. * libguile/vm.c (vm_reinstate_partial_continuation): Don't push on a number-of-values marker. commit 56de3a697617332b6738611fa0b926a8e9d996d7 Author: Andy Wingo <[email protected]> Date: Sun Oct 20 15:49:22 2013 +0200 VM has "builtins": primitives addressable by emitted RTL code * libguile/Makefile.am: * libguile/vm-builtins.h: New header, declaring stubs needed by the compiler like values, apply, and abort-to-prompt. * libguile/vm.c: Adapt the apply and values stubs to conform to a standard interface. Add an abort-to-prompt stub. (scm_vm_builtin_ref): New helper, for the builtin-ref opcode. (scm_vm_builtin_name_to_index) (scm_vm_builtin_index_to_name): New helpers, for the compiler and disassembler, respectively. (scm_init_vm_builtins, scm_bootstrap_vm): Allow the compiler helpers to be loaded later into a module. * module/language/rtl.scm: Export builtin-index->name and builtin-name->index. * libguile/vm-engine.c (RETURN_VALUE_LIST): Update to use new names of "apply" and "values". (abort): Update to be a tail VM op, and reorder and renumber other ops. (builtin-ref): New opcode. * module/language/tree-il/compile-cps.scm (convert): Convert to 'abort-to-prompt calls, possibly with 'apply, effectively undoing the tree-il transformation. * module/language/cps/reify-primitives.scm (builtin-ref): New helper. (reify-primitives): Convert builtin primitives to builtin-ref. * module/language/cps/dfg.scm (constant-needs-allocation?): * module/language/cps/compile-rtl.scm (emit-rtl-sequence): Add support for compiling builtin-ref. * module/system/vm/disassembler.scm (code-annotation): Add annotation for builtin-ref. commit 749475bec492a61c4bbb41570eaf954e28e3fc37 Author: Andy Wingo <[email protected]> Date: Fri Oct 18 19:33:50 2013 +0200 Partial continuations are RTL stubs * libguile/control.c: Implement partial continuations as RTL programs. * libguile/programs.c (scm_i_rtl_program_minimum_arity): Add partial continuation case. * libguile/vm-engine.c (compose-continuation): Fix to look for vm_cont from the free variables. * libguile/vm-i-system.c (abort): Poison continuations captured in the stack VM, as the can't be rewound by the RTL stubs. ----------------------------------------------------------------------- hooks/post-receive -- GNU Guile
