This reverts commit 2615030c521afc822c66a7e139ccba3d2365ab56,
which doesn't work when cross compiling, except for mingw.

vm_getivar() provides fastpath for T_OBJECT by caching an index
of ivar. This patch also provides fastpath for FL_EXIVAR objects.
FL_EXIVAR objects have an each ivar array and index can be cached
as T_OBJECT. To access this ivar array, generic_iv_tbl is exposed
by rb_ivar_generic_ivtbl() (declared in variable.h which is newly
introduced).
Benchmark script:
Benchmark.driver(repeat_count: 3){|x|
x.executable name: 'clean', command: %w'../clean/miniruby'
x.executable name: 'trunk', command: %w'./miniruby'
objs = [Object.new, 'str', {a: 1, b: 2}, [1, 2]]
objs.each.with_index{|obj, i|
rep = obj.inspect
rep = 'Object.new' if /\#/ =~ rep
x.prelude str = %Q{
v#{i} = #{rep}
def v#{i}.foo
@iv # ivar access method (attr_reader)
end
v#{i}.instance_variable_set(:@iv, :iv)
}
puts str
x.report %Q{
v#{i}.foo
}
}
}
Result:
v0.foo # T_OBJECT
clean: 85387141.8 i/s

The script in prelude.rb was embed in MRI to load it (eval this
script at everyboot).
This commit change the loading process of prelude.rb. MRI doesn't
eval a script, but load from compiled binary with builtin feature.
So that Init_prelude() does not load `prelude.rb` now.

FreeBSD make works differently with `-j` option.

Stop using exit, cd, exec in middle of commands.

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.

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.

This update does not add any new codepoint assignments, it just
expands the range of emoji codepoint sequences recommended for
public interchange.
Depending on how emoji data files are cached, this commit may
require manual intervention in some build environments
(including some CI systems).

To perform a regular method call, the VM needs two structs,
`rb_call_info` and `rb_call_cache`. At the moment, we allocate these two
structures in separate buffers. In the worst case, the CPU needs to read
4 cache lines to complete a method call. Putting the two structures
together reduces the maximum number of cache line reads to 2.
Combining the structures also saves 8 bytes per call site as the current
layout uses separate two pointers for the call info and the call cache.
This saves about 2 MiB on Discourse.
This change improves the Optcarrot benchmark at least 3%. For more
details, see attached bugs.ruby-lang.org ticket.
Complications:
- A new instruction attribute `comptime_sp_inc` is introduced to
calculate SP increase at compile time without using call caches. At
compile time, a `TS_CALLDATA` operand points to a call info struct, but
at runtime, the same operand points to a call data struct. Instruction
that explicitly define `sp_inc` also need to define `comptime_sp_inc`.
- MJIT code for copying call cache becomes slightly more complicated.
- This changes the bytecode format, which might break existing tools.

Requested by ko1 that ability of calling rb_raise from anywhere
outside of GVL is "too much". Give up that part, move the GVL
aquisition routine into gc.c, and make our new gc_raise().
|
|
|
|
Now that allocation routines like ALLOC_N() can raise exceptions
on integer overflows. This is a problem when the calling thread
has no GVL. Memory allocations has been allowed without it, but
can still fail.
Let's just relax rb_raise's restriction so that we can call it
with or without GVL. With GVL the behaviour is unchanged. With
no GVL, wait for it.
Also, integer overflows can theoretically occur during GC when
we expand the object space. We cannot do so much then. Call
rb_memerror and let that routine abort the process.

Rules which have used CPPFLAGS will need XCFLAGS or INCFLAGS now.
|
|
INCFLAGS is not included in CPPFLAGS on mswin, not to be exported
to rbconfig.rb.

Flags for ruby core such as warning and `_FORTIFY_SOURCE` macro
are not necessary to make fake.rb, except for `RUBY_EXPORT` macro
which prevents to include ruby/backward.h.
