Koichi Sasada d9bf9c572f take care of USE_LAZY_LOAD=1.
On USE_LAZY_LOAD=1, the iseq should be loaded. So rb_iseq_check()
is needed. Furthermore, now lazy loading with builtin_function_table
is not supported, so it should cancel lazy loading.

Koichi Sasada 7f5014e6e8 rely on sorted compiled binary array.
`builtin_binary` is sorted by miniruby loading order and this
loading order should be same on ruby. So we can believe sorted
order of `builtin_binary` on boot time.

Koichi Sasada 40026a408d support cross-compilation.
On cross-compilation, compiled binary can no be created because
compiled binary should be created by same interpreter (on cross-
compilation, host ruby is used to build ruby (BASERUBY)).
So that cross-compilation system loads required scripts in text.
It is same as miniruby.

Koichi Sasada 2c5c60754c use compiled binary for gem_prelude.rb.
`gem_prelude.rb` is not compiled yet. This patch compile it to
compiled binary.

Koichi Sasada 179062dd80 move rb_vm_lvar_exposed() correctly.
rb_vm_lvar_exposed() is prepared for __builtin_inline!(), needed for
mini_builtin.c and builtin.c. However, it's only on builtin.c.
So move it to make it as a part of VM.

Koichi Sasada 3141642380 __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.

Full-path of builtin scripts no longer needed 2019-11-09 19:43:14 +09:00
Koichi Sasada b5d8849220 Revert "don't embed full-path."
This reverts commit dfac2e9eb3.

It does not work if cwd is different from builddir...

Koichi Sasada dfac2e9eb3 don't embed full-path.
miniruby load *.rb from srcdir. To specify file path,
tool/mk_builtin_loader.rb embed full path of each *.rb file.
However it prevent to pre-generation of required files for tarball.
This patch generate srcdir/*.rb from __FILE__ information.

Koichi Sasada 83c563cfa4 cstr -> bytes
rb_iseq_ibf_load_cstr() accepts bytes, but not NUL-terminate
C string. To make it clear, rename it to _bytes.

Koichi Sasada 46acd0075d 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.
