2019-05-23Use 'scm_from_utf8_{string,symbol,keyword}' for C string literals.Mark H Weaver1-10/+10
Partial fix for <https://bugs.gnu.org/33044>. Reported by Tom de Vries <tdevries@suse.de>. Fix several instances of the mistake of using 'scm_from_locale_*' for C strings that originally came from a C string literal. Change several uses of 'scm_from_latin1_*' as well, to promote the practice of writing code that works for arbitrary C string literals. Also add missing years to the copyright notices of changed files, based on the git history. * libguile/debug-malloc.c, libguile/deprecation.c, libguile/error.c, libguile/eval.c, libguile/expand.c, libguile/extensions.c, libguile/filesys.c, libguile/init.c, libguile/load.c, libguile/modules.c, libguile/pairs.c, libguile/posix.c, libguile/print.c, libguile/random.c, libguile/read.c, libguile/regex-posix.c, libguile/snarf.h, libguile/srfi-13.c, libguile/stacks.c, libguile/stime.c, libguile/strports.c, libguile/values.c: Use 'scm_from_utf8_*' where appropriate.

Update to newest recommended license notices from the FSF. Everything stays LGPLv3+ except guile-readline which is GPLv3+.
2018-06-20Remove (C) from copyright statementsAndy Wingo1-1/+1
As the FSF advises, 'There is no legal significance to using the three-character sequence “(C)”, but it does no harm.' It does take up space though! For that reason, we remove it here from our C files.

2015-10-21VM stack grows downwardAndy Wingo1-10/+8
Adapt VM stack to grow downward. This will make native compilation look more like the VM code, as we will be able to use native CALL instructions, taking proper advantage of the return address buffer. * libguile/continuations.c (scm_i_continuation_to_frame): Record offsets from stack top. * libguile/control.c (scm_i_prompt_pop_abort_args_x): Adapt for reversed order of arguments, and instead of relying on the abort to push on the number of arguments, make the caller save the stack depth, which allows us to compute the number of arguments ourselves. (reify_partial_continuation, scm_c_abort): Adapt to reversed stack order. * libguile/dynstack.c (scm_dynstack_wind_prompt): Since we wind the stack in a downward direction, subtract the reloc instead of adding it. * libguile/dynstack.h (SCM_F_DYNSTACK_PROMPT_ESCAPE_ONLY): Remove flag; instead rely on prompt-establishing code to save the stack depth. * libguile/eval.c (eval): Remove extraneous "volatile" declarations for variables that are not re-set between the setjmp and any longjmp. Adapt to save stack depth before instating the prompt. * libguile/foreign.c (scm_i_foreign_call): Adapt to receive arguments in reverse order. * libguile/frames.c (frame_stack_top, scm_i_frame_stack_top): Adapt to compute stack top instead of stack bottom. (scm_c_frame_closure): Adapt to stack growth change. (scm_frame_num_locals, scm_frame_local_ref, scm_frame_set_x): Use union data type to access stack. (RELOC): Reformat. (scm_c_frame_previous): Adapt to stack growth change. * libguile/frames.h: Adapt stack diagram to indicate that the stack grows up. (union scm_vm_stack_element): New data type used to access items on the stack. (SCM_FRAME_PREVIOUS_SP) (SCM_FRAME_RETURN_ADDRESS, SCM_FRAME_SET_RETURN_ADDRESS) (SCM_FRAME_DYNAMIC_LINK, SCM_FRAME_SET_DYNAMIC_LINK) (SCM_FRAME_LOCAL, SCM_FRAME_NUM_LOCALS): Adapt to stack representation change. (SCM_FRAME_SLOT): New helper. (SCM_VM_FRAME_FP, SCM_VM_FRAME_SP): Adapt to stack growth change. * libguile/stacks.c (scm_make_stack): Record offsets from top of stack. * libguile/throw.c (catch): Adapt to scm_i_prompt_pop_abort_args_x change. * libguile/vm-engine.c (ALLOC_FRAME, RESET_FRAME): (FRAME_LOCALS_COUNT_FROM): Adapt to stack growth change. (LOCAL_ADDRESS): Use SCM_FRAME_SLOT to get the address as the proper data type. (RETURN_ONE_VALUE, RETURN_VALUE_LIST): Adapt to stack growth change. (apply): Shuffling up the SMOB apply args can cause the stack to expand, so use ALLOC_FRAME instead of RESET_FRAME. (vm_engine): Adapt for stack growth change. * libguile/vm.c (vm_increase_sp, vm_push_sp, vm_restore_sp): Adapt to stack representation change. (scm_i_vm_cont_to_frame): Adapt to take offsets from the top. (scm_i_vm_capture_stack): Adapt to capture from the top. (vm_return_to_continuation_inner): Adapt for data type changes. (vm_return_to_continuation): Likewise, and instead of looping, just splat the saved arguments on with memcpy. (vm_dispatch_hook): Adapt to receive arguments in the reverse order. Adapt callers. (vm_abort): There is never a tail argument. Adapt to stack representation change. (vm_reinstate_partial_continuation) (vm_reinstate_partial_continuation_inner): Adapt to stack growth change. (allocate_stack, free_stack): Adapt to data type change. (expand_stack): Don't try to mremap(), as you can't grow a mapping from the bottom. Without knowing that there's a free mapping space right below the old stack, which there usually isn't on Linux, we have to copy. We can't use MAP_GROWSDOWN because Linux is buggy. (make_vm): Adapt to stack representation changes. (return_unused_stack_to_os): Round down instead of up, as the stack grows down. (scm_i_vm_mark_stack): Adapt to walk up the stack. (scm_i_vm_free_stack): Adapt to scm_vm changes. (vm_expand_stack_inner, reset_stack_limit, vm_expand_stack): Adapt to the stack growing down. (scm_call_n): Adapt to the stack growing down. Don't allow argv to point into the stack. * libguile/vm.h (struct scm_vm, struct scm_vm_cont): Adapt to hold the stack top and bottom.

2013-11-21scm_the_vm now returns raw struct scm_vm pointerAndy Wingo1-2/+2
* libguile/vm.h (scm_the_vm): Return struct scm_vm*. (scm_c_vm_run): Remove. * libguile/control.c: * libguile/eval.c: * libguile/throw.c: * libguile/vm.c: Adapt.
2013-11-21Prefer scm_call_n to scm_c_vm_run (scm_the_vm())Andy Wingo1-20/+16
* libguile/vm.c (scm_i_capture_current_stack): Cosmetic tweak. (scm_call_n): Define here instead of in eval.c. All callers of scm_c_vm_run were passing scm_the_vm() as the VM. Eventually scm_call_n will replace scm_c_vm_run. * libguile/eval.c: Adapt all callers.
2013-11-21scm_i_prompt_pop_abort_args_x takes struct scm_vm* as argAndy Wingo1-11/+13
* libguile/control.h: * libguile/control.c (scm_i_prompt_pop_abort_args_x): Change to take VP as an arg, not VM. * libguile/eval.c (eval): * libguile/throw.c (pre_init_catch): Adapt.
2013-11-21The dynamic stack records SP and FP values as offsetsAndy Wingo1-8/+8
* libguile/dynstack.h: * libguile/dynstack.c (PROMPT_FP, PROMPT_SP): (scm_dynstack_push_prompt, scm_dynstack_find_prompt): Prompts on the dynstack are recorded as offsets from the base stack address in this thread. * libguile/control.c (scm_c_abort): * libguile/eval.c (eval): * libguile/stacks.c (find_prompt, narrow_stack): * libguile/throw.c (pre_init_catch): * libguile/vm-engine.c (prompt): Adapt.
2013-11-21Change eval.c to use scm_c_vm_run instead of scm_call_with_vm.Andy Wingo1-24/+32
* libguile/eval.c (scm_apply_0, scm_apply_1, scm_apply_2, scm_apply_3) (scm_map, scm_for_each, scm_apply): Change to prefer scm_apply_0, and to have it call vm_run instead of call_with_vm. (eval): Use scm_apply_0 and scm_call_0. * libguile/srfi-1.c (scm_srfi1_count): Use scm_apply_0.
2013-10-31Be smarter about capturing the environment for memoized codeAndy Wingo1-21/+8
* libguile/memoize.h (SCM_M_CAPTURE_MODULE) * libguile/memoize.c (MAKMEMO_CAPTURE_MODULE, capture_env): (maybe_makmemo_capture_module, memoize): Determine when to capture the module on the environment chain at compile-time, instead of at runtime. Introduces a new memoized expression type, capture-module. (scm_memoized_expression): Start memoizing with #f as the environment. (unmemoize): Add unmemoizer. (scm_memoize_variable_access_x): Cope with #f as module, and treat as the root module (captured before modules were booted). * libguile/eval.c (eval): * module/ice-9/eval.scm (primitive-eval): Adapt.
2013-10-27Memoized expressions are pairs, not SMOBsAndy Wingo1-3/+1
* libguile/memoize.c (MAKMEMO): Memoized objects are pairs now, not SMOBs. This lets eval.scm destructure them more efficiently. (scm_print_memoized, scm_memoized_p, scm_memoized_expression_typecode) (scm_memoized_expression_data): Remove these interfaces. (unmemoize, scm_memoize_variable_access_x): Remove SMOB type checks. (scm_init_memoize): Remove SMOB type definition. * libguile/memoize.h (scm_tc16_memoized, SCM_MEMOIZED_P) (scm_memoized_expression_typecode, scm_memoized_expression_data) (scm_memoized_p): Remove declarations. * libguile/validate.h (SCM_VALIDATE_MEMOIZED): Remove declaration. * libguile/eval.c (eval): Remove memoized type check, and inline the inum unpacking. * module/ice-9/eval.scm (memoized-expression-case): Use car and cdr to destructure memoized expressions. A big win!
2013-10-25Evaluator uses two-dimensional environmentAndy Wingo1-88/+148
* libguile/memoize.c (MAKMEMO_LEX_REF, MAKMEMO_LEX_SET): Change to address lexicals by depth and width. (try_lookup_rib, lookup_rib, make_pos): New helpers. (lookup): Adapt to return a pair. (memoize, unmemoize_bindings, unmemoize_lexical): Adapt. * libguile/eval.c (eval, prepare_boot_closure_env_for_eval): (prepare_boot_closure_env_for_apply): * module/ice-9/eval.scm (make-fixed-closure, make-general-closure) (eval): Adapt to new environment. This is currently a slight win for C, and a slight lose for Scheme -- because the lookup loop is so poorly compiled by the stack VM. I expect that the RTL-compiled eval will fix this.
2013-10-14Add SCM_F_DYNSTACK_PROMPT_PUSH_NARGS prompt flagAndy Wingo1-1/+2
* libguile/dynstack.h (scm_t_dynstack_prompt_flags): New flag, SCM_F_DYNSTACK_PROMPT_PUSH_NARGS, set if the continuation expects the number of args to be pushed on the top of the stack. * libguile/control.c (scm_c_abort): Only push nargs if requested. * libguile/eval.c (eval): * libguile/throw.c (pre_init_catch): * libguile/vm-i-system.c (prompt): Set SCM_F_DYNSTACK_PROMPT_PUSH_NARGS.
