From 31416423809f64d4b5ea6b9651cced3179cc5ced Mon Sep 17 00:00:00 2001 From: Koichi Sasada Date: Mon, 11 Nov 2019 16:38:46 +0900 Subject: __builtin_inline! Add an experimental `__builtin_inline!(c_expression)` special intrinsic which run a C code snippet. In `c_expression`, you can access the following variables: * ec (rb_execution_context_t *) * self (const VALUE) * local variables (const VALUE) Not that you can read these variables, but you can not write them. You need to return from this expression and return value will be a result of __builtin_inline!(). Examples: `def foo(x) __builtin_inline!('return rb_p(x);'); end` calls `p(x)`. `def double(x) __builtin_inline!('return INT2NUM(NUM2INT(x) * 2);')` returns x*2. --- vm_core.h | 1 + 1 file changed, 1 insertion(+) (limited to 'vm_core.h') diff --git a/vm_core.h b/vm_core.h index 9e158df923..9c5b723d6a 100644 --- a/vm_core.h +++ b/vm_core.h @@ -652,6 +652,7 @@ typedef struct rb_vm_struct { st_table *frozen_strings; const struct rb_builtin_function *builtin_function_table; + int builtin_inline_index; /* params */ struct { /* size in byte */ -- cgit v1.2.3
