Andy Wingo 6f16379e9a allocate free variables inline to closures ... * libguile/_scm.h (SCM_OBJCODE_MINOR_VERSION): Bump. * libguile/programs.h (SCM_PROGRAM_FREE_VARIABLES) (SCM_PROGRAM_FREE_VARIABLE_REF, SCM_PROGRAM_FREE_VARIABLE_SET) (SCM_PROGRAM_NUM_FREE_VARIABLES): * libguile/programs.c (scm_make_program, scm_program_num_free_variables) (scm_program_free_variable_ref, scm_program_free_variable_set_x): Allocate free variables inline with programs, instead of being in a vect. Should improve locality, and require fewer local variables in the VM. * libguile/vm-engine.c (vm_engine): Remove free_vars and free_vars_count variables. * libguile/vm-engine.h (CACHE_PROGRAM): No need to muck with free_vars and free_vars_count. (CHECK_FREE_VARIABLE): Update for inline free vars. * libguile/vm-i-system.c (FREE_VARIABLE_REF): Update for inline free vars. (make-closure, fix-closure): Take the closure vals as separate stack args, and copy or fix them inline into the appropriate closure. * module/language/objcode/spec.scm (program-free-variables): Define a local version of this removed function. * module/language/tree-il/compile-glil.scm (flatten): Adjust to not make a vector when making closures. * module/system/vm/program.scm: Export program-num-free-variables, program-free-variable-ref, program-free-variable-set!, and remove program-free-variables. * test-suite/tests/tree-il.test ("lambda"): Update to not make vectors when making closures.		2010-01-09 16:43:26 +01:00
