Tabs were expanded because the file did not have any tab indentation in unedited lines.
Please update your editor config, and use misc/expand_tabs.rb in the pre-commit hook.

Currently this has a fairly minor effect as strings are not used heavily
inside the builtins (outside of warnings, requires, and errors).
Hopefully this allows us to use strings in the future where appropriate.

Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).

Now, C functions written by __builtin_cexpr!(code) and others are
named as "__builtin_inline#{n}". However, it is difficult to know
what the function is. This patch rename them into
"__builtin_foo_#{lineno}" when cexpr! is in 'foo' method.

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.

prelude.c is an automatically generated file by template/prelude.c.tmpl.
However it does not contain any required functions. So remove it from
dependency.
Also miniprelude.c is included by mini_builtin.c and does not need
to make miniprelude.o.

`gem_prelude.rb` is not compiled yet. This patch compile it to
compiled binary.

opt_invokebuiltin_delegate and opt_invokebuiltin_delegate_leave
invokes builtin functions with same parameters of the method.
This technique eliminate stack push operations. However, delegation
parameters should be completely same as given parameters.
(e.g. `def foo(a, b, c) __builtin_foo(a, b, c)` is okay, but
__builtin_foo(b, c) is not allowed)
This patch relaxes this restriction. ISeq has a local variables
table which includes parameters. For example, the method defined
as `def foo(a, b, c) x=y=nil`, then local variables table contains
[a, b, c, x, y]. If calling builtin-function with arguments which
are sub-array of the lvar table, use opt_invokebuiltin_delegate
instruction with start index. For example, `__builtin_foo(b, c)`,
`__builtin_bar(c, x, y)` is okay, and so on.

Instead of reading from the files by the full-path at runtime. As
rbinc files need to be included in distributed tarballs, the
full-paths at the packaging are unavailable at compilation times.

This reverts commit dfac2e9eb3d697e56d91151584f1d3cf9d2c79c9.
It does not work if cwd is different from builddir...

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.

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.
