Andy Wingo	c2a8224a63	Rework VM approach to shuffling unknown numbers of args ... * libguile/vm-engine.c (shuffle-down, expand-apply-argument): New instructions. (tail-call, tail-call-label, return-values): Don't reset the frame. The compiler should reset the frame appropriately. (tail-call/shuffle, tail-apply): Remove unused instructions. * libguile/vm.c (vm_builtin_apply_code): Use new shuffle-down and expand-apply-argument opcodes. (vm_builtin_call_with_values_code): Replace tail-call/shuffle with shuffle-down then tail-call. * libguile/jit.c (compile_shuffle_down, compile_expand_apply_argument): Add compiler stubs (COMPILE_X8_F12_F12): New definition. (compile_tail_call_shuffle, compile_tail_apply): Remove unused compilers. * module/language/cps/compile-bytecode.scm (compile-function): Emit reset-frame before tail calls and returns. * module/system/vm/assembler.scm (system): Remove unbound "emit-return" export. * module/system/vm/disassembler.scm (code-annotation) (instruction-has-fallthrough?, define-stack-effect-parser): Adapt for opcode changes.	2018-07-20 11:42:30 +02:00
Andy Wingo	80ba0e2cb1	Make JIT compiler skeleton more terse ... * libguile/jit.c (scm_jit_state): Add "ip" member so we don't have to be passing it around all the time. Rename use variables to "j" from "state".	2018-07-20 11:42:13 +02:00
Andy Wingo	5577392738	Begin structure for template JIT compiler ... * libguile/jit.c: Begin to wire up compilers for the VM opcodes. Currently all that's there is a parser for each opcode's operands.	2018-07-03 13:31:29 +02:00
Andy Wingo	9338ef15c2	Wire up lightning into libguile build ... * libguile/Makefile.am (AM_CPPFLAGS): (libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES): If ENABLE_JIT, build lightning. (EXTRA_DIST): Add lightning files. * libguile/lightning/lightning.am (lightning_extra_files): Add COPYING and related files to the dist. * libguile/jit.c: * libguile/jit.h: New files.	2018-07-02 11:08:57 +02:00
