* Bump objcode versionAndy Wingo2021-05-111-1/+1
| | | | | | * libguile/loader.h (SCM_OBJCODE_MINOR_VERSION): * module/system/vm/assembler.scm (*bytecode-minor-version*): Bump, as we're going to start adding inlinable exports.
* Bump minor objcode version for new intrinsicsAndy Wingo2021-04-261-2/+2
| | | | | * libguile/loader.h (SCM_OBJCODE_MINOR_VERSION): Bump. * module/system/vm/assembler.scm (*bytecode-minor-version*): Bump.
* Bump objcode minor version to 4Andy Wingo2020-08-261-1/+1
| | | | | | * libguile/loader.h (SCM_OBJCODE_MINOR_VERSION): Accept up to version 4. * module/system/vm/assembler.scm (*bytecode-minor-version*): Produce version 4.
* Bump objcode minor versionAndy Wingo2020-05-131-1/+1
| | | | | | * libguile/loader.h (SCM_OBJCODE_MINOR_VERSION): * module/system/vm/assembler.scm (*bytecode-minor-version*): Bump, so that compiled files from Guile 3.0.3 will error when loaded on 3.0.2.
* Bump objcode minor version in preparation for new stable seriesAndy Wingo2020-01-131-3/+3
| | | | | | * libguile/loader.h (SCM_OBJCODE_MINIMUM_MINOR_VERSION): (SCM_OBJCODE_MINOR_VERSION): * module/system/vm/assembler.scm (*bytecode-minor-version*): Bump.
* Renumber instructions and bump objcode versionv2.3.0Andy Wingo2018-09-201-2/+2
| | | | | | | | * libguile/loader.h (SCM_OBJCODE_MINIMUM_MINOR_VERSION): (SCM_OBJCODE_MINOR_VERSION): Bump version. * module/system/vm/assembler.scm (*bytecode-minor-version*): Bump. * libguile/vm-engine.c: Rearrange opcodes to be contiguous and in a somewhat sensible order.
* Revert "Add support for reading ELF symbol table from C"Andy Wingo2018-07-291-5/+2
| | | | | This reverts commit e95f15c932650783f34253e396216c66050905f0. It's no longer needed given the current JIT strategy.
* Add support for reading ELF symbol table from CAndy Wingo2018-07-201-2/+5
| | | | | | | | | | | | * libguile/loader.c (scm_i_program_address_range): New function. Currently unused, will wire up once we correct the compiler to emit symbols whose values are relative to the base addr. Will be used by JIT so it needs to be fast. (register_elf): Rework to be less verbose, and record symtab/strtab. (struct mapped_elf_image): Add symtab and strtab members. (load_thunk_from_memory, process_dynamic_segment): Parse out DT_SYMTAB and DT_STRTAB. (Elf_Sym): New definition.
* Replace uses of scm_t_int8, scm_t_uintmax, etc with stdint typesAndy Wingo2018-06-211-2/+2

* Update license notices in all C filesAndy Wingo2018-06-201-17/+17
| | | | | Update to newest recommended license notices from the FSF. Everything stays LGPLv3+ except guile-readline which is GPLv3+.
* libguile header files have uniform format for copyright declarationsAndy Wingo2018-06-201-1/+2
|
* Remove (C) from copyright statementsAndy Wingo2018-06-201-1/+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.
* Rename __scm.h to scm.hAndy Wingo2018-06-201-1/+1
| | | | * libguile/scm.h: Rename. Update all includers.
* Remove Emacs local variables comments in Guile sourceAndy Wingo2018-06-201-6/+0

* Move some definitions out of _scm.hAndy Wingo2018-06-171-0/+30
| | | | | | | | | | * libguile/_scm.h: * libguile/loader.h (SCM_OBJCODE_ENDIANNESS): (SCM_OBJCODE_WORD_SIZE, SCM_OBJCODE_MAJOR_VERSION): (SCM_OBJCODE_MINOR_VERSION, SCM_OBJCODE_MAJOR_VERSION_STRING): (SCM_OBJCODE_MINOR_VERSION_STRING): (SCM_OBJCODE_VERSION_STRING, SCM_OBJCODE_MACHINE_VERSION_STRING): Move definitions to loader.h.
* Fix libguile subcomponent headers not to include <libguile.h>Andy Wingo2018-06-141-2/+2
| | | | | | | | | | | | | | | | | | | * libguile/bytevectors.h: Include uniform.h, for use in the macros. * libguile/extensions.h: Include libpath.h, for the SCM_EFFECTIVE_VERSION, which is almost always used with these routines. * libguile/frames.h: * libguile/instructions.h: * libguile/intrinsics.h: * libguile/loader.h: * libguile/programs.h: * libguile/vm.h: Include <libguile/__scm.h> instead of <libguile.h>. Cuts a circular include, but also precipitates a lot of maintenance in the .c files. * libguile/*.c: Update C files to add needed all needed includes that before were getting automatically pulled in by the indirect inclusion of libguile.h.
* VM support for raw slotsAndy Wingo2015-10-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | * libguile/loader.c (scm_find_slot_map_unlocked): Rename from scm_find_dead_slot_map_unlocked. * libguile/vm.c (struct slot_map_cache_entry, struct slot_map_cache) (find_slot_map): Rename, changing "dead_slot" to "slot". (enum slot_desc): New type. (scm_i_vm_mark_stack): Interpret slot maps as having two bits per slot, allowing us to indicate that a slot is live but not a pointer. * module/language/cps/compile-bytecode.scm (compile-function): Adapt to emit-slot-map name change. * module/system/vm/assembler.scm (<asm>): Rename dead-slot-maps field to slot-maps. (emit-slot-map): Rename from emit-dead-slot-map. (link-frame-maps): 2 bits per slot. * module/language/cps/slot-allocation.scm (lookup-slot-map): Rename from lookup-dead-slot-map. (compute-var-representations): New function. (allocate-slots): Adapt to encode two-bit slot representations.
* More precise stack marking via .guile.frame-maps sectionAndy Wingo2014-01-261-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | * module/language/cps/slot-allocation.scm (lookup-dead-slot-map) (allocate-slots): For each non-tail call in a function, compute the set of slots that are dead after the function has begun the call. * module/language/cps/compile-bytecode.scm (compile-fun): Emit the `dead-slot-map' macro instruction for non-tail calls. * module/system/vm/assembler.scm (<asm>): Add `dead-slot-maps' member. (dead-slot-map): New macro-instruction. (link-frame-maps, link-dynamic-section, link-objects): Write dead slots information into .guile.frame-maps sections of ELF files. * module/system/vm/elf.scm (DT_GUILE_FRAME_MAPS): New definition. * libguile/loader.h: * libguile/loader.c (DT_GUILE_FRAME_MAPS, process_dynamic_segment): (load_thunk_from_memory, register_elf): Arrange to parse DT_GUILE_FRAME_MAPS out of the dynamic section. (find_mapped_elf_image_unlocked, find_mapped_elf_image): New helpers. (scm_find_mapped_elf_image): Refactor. (scm_find_dead_slot_map_unlocked): New interface. * libguile/vm.c (scm_i_vm_mark_stack): Mark the hottest frame conservatively, as before. Otherwise use the dead slots map, if available, to avoid marking data that isn't live.
* Rename objcodes?.{scm,c,h} to loader.{scm,c,h}Andy Wingo2013-11-191-0/+36
* libguile/loader.c: * libguile/loader.h: Rename from objcodes.[ch]. * module/system/vm/loader.scm: Rename from objcode.scm. * libguile/Makefile.am: * libguile/gsubr.c: * libguile/init.c: * libguile/procs.c: * libguile/vm.c: * module/Makefile.am: * module/ice-9/eval-string.scm: * module/language/rtl/spec.scm: * module/system/base/target.scm: * module/system/repl/command.scm: * module/system/repl/common.scm: * module/system/vm/debug.scm: * module/system/vm/disassembler.scm: * module/system/vm/objcode.scm: * test-suite/tests/compiler.test: * test-suite/tests/dwarf.test: * test-suite/tests/rtl-compilation.test: * test-suite/tests/rtl.test: Adapt.
