Stacks are emulated in MJIT, must not touch the original VM stack.

This commit fixes compiler error on MSVC. %p on that platform is not
suitable to represent a compile-time constant.

We can obtain the verbatim source code of Primitive.cexpr!. Why not
paste that content into the JITed program.

Noticed that struct rb_builtin_function is a purely compile-time
constant. MJIT can eliminate some runtime calculations by statically
generate dedicated C code generator for each builtin functions.

Recent changes break Primitive.cinit!(c_code) so fix it.
|
|
Primitve.cexpr! and .cstmt! can access Ruby's parameter and
*local variables* (note that local parameters are also local
variables). However recent changes only allow to access
parameters. This patch fix it.
For example, the following code can work:
def foo a, b, k: :kw, **kwrest
c = a + b
d = k
e = kwrest
p Primitive.cstmt!(%q(rb_p(rb_ary_new_from_args(5, a, b, c, d, e));
return Qnil;))
end

To suppress warnings by Visual C.
```
./integer.rb(5) : warning C4129: 'i' : unrecognized character escape sequence
./kernel.rb(21) : warning C4129: 'k' : unrecognized character escape sequence
```

with Ripper.
a3e6f52c17061f012c4e638b3343b57752ed7603 introduced __builtin_cexpr! and
__builtin_cstmt!, but nobody has used them and then they broke on
79292b30884ebcd8be028a7f3c9ccafd7759f2ae by undefined `params`.
This patch fixes the undefined `params`, but still we're not using them
yet.

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.
|
|
rename __builtin_inline!(code) to __builtin_cstmt(code).
Also this commit introduce the following inlining C code features.
* __builtin_cstmt!(STMT)
(renamed from __builtin_inline!)
Define a function which run STMT implicitly and call this function at
evatuation time. Note that you need to return some value in STMT.
If there is a local variables (includes method parameters), you can
read these values.
static VALUE func(ec, self) {
VALUE x = ...;
STMT
}
Usage:
def double a
# a is readable from C code.
__builtin_cstmt! 'return INT2FIX(FIX2INT(a) * 2);'
end
* __builtin_cexpr!(EXPR)
Define a function which invoke EXPR implicitly like `__builtin_cstmt!`.
Different from cstmt!, which compiled with `return EXPR;`.
(`return` and `;` are added implicitly)
static VALUE func(ec, self) {
VALUE x = ...;
return EXPPR;
}
Usage:
def double a
__builtin_cexpr! 'INT2FIX(FIX2INT(a) * 2)'
end
* __builtin_cconst!(EXPR)
Define a function which invoke EXPR implicitly like cexpr!.
However, the function is called once at compile time, not evaluated time.
Any local variables are not accessible (because there is no local variable
at compile time).
Usage:
GCC = __builtin_cconst! '__GNUC__'
* __builtin_cinit!(STMT)
STMT are writtein in auto-generated code.
This code does not return any value.
Usage:
__builtin_cinit! '#include <zlib.h>'
def no_compression?
__builtin_cconst! 'Z_NO_COMPRESSION ? Qtrue : Qfalse'
end

Update the target file itself of the dependency on this script.
Fall back to the current working directory if unwritable.

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.

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.

The insn array includes not only an array but also some literal objects.

If there is a type mismatch between expected builtin function type
and actual function type, C compiler shows warning.
For example, `__builtin_func(1, 2)` expects
`func(rb_ec_t*, VALUE self, VALUE p1, VALUE p2)` function definition.
However, it is easy to overlook "warning" messages. So this patch
changes to stop compiling as an error if there is a mismatch.

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.
