From 46acd0075d80c2f886498f089fde1e9d795d50c4 Mon Sep 17 00:00:00 2001 From: Koichi Sasada Date: Thu, 7 Nov 2019 16:58:00 +0900 Subject: support builtin features with Ruby and C. Support loading builtin features written in Ruby, which implement with C builtin functions. [Feature #16254] Several features: (1) Load .rb file at boottime with native binary. Now, prelude.rb is loaded at boottime. However, this file is contained into the interpreter as a text format and we need to compile it. This patch contains a feature to load from binary format. (2) __builtin_func() in Ruby call func() written in C. In Ruby file, we can write `__builtin_func()` like method call. However this is not a method call, but special syntax to call a function `func()` written in C. C functions should be defined in a file (same compile unit) which load this .rb file. Functions (`func` in above example) should be defined with (a) 1st parameter: rb_execution_context_t *ec (b) rest parameters (0 to 15). (c) VALUE return type. This is very similar requirements for functions used by rb_define_method(), however `rb_execution_context_t *ec` is new requirement. (3) automatic C code generation from .rb files. tool/mk_builtin_loader.rb creates a C code to load .rb files needed by miniruby and ruby command. This script is run by BASERUBY, so *.rb should be written in BASERUBY compatbile syntax. This script load a .rb file and find all of __builtin_ prefix method calls, and generate a part of C code to export functions. tool/mk_builtin_binary.rb creates a C code which contains binary compiled Ruby files needed by ruby command. --- vm_core.h | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'vm_core.h') diff --git a/vm_core.h b/vm_core.h index fabe8bbc10..9e158df923 100644 --- a/vm_core.h +++ b/vm_core.h @@ -564,6 +564,10 @@ typedef struct rb_hook_list_struct { unsigned int running; } rb_hook_list_t; + +// see builtin.h for definition +typedef const struct rb_builtin_function *RB_BUILTIN; + typedef struct rb_vm_struct { VALUE self; @@ -647,6 +651,8 @@ typedef struct rb_vm_struct { VALUE *defined_strings; st_table *frozen_strings; + const struct rb_builtin_function *builtin_function_table; + /* params */ struct { /* size in byte */ size_t thread_vm_stack_size; @@ -880,6 +886,9 @@ typedef struct rb_execution_context_struct { } machine; } rb_execution_context_t; +// for builtin.h +#define VM_CORE_H_EC_DEFINED 1 + // Set the vm_stack pointer in the execution context. void rb_ec_set_vm_stack(rb_execution_context_t *ec, VALUE *stack, size_t size); -- cgit v1.2.1
