This keeps ci->flag and ci->aux.index consistent across 32-bit
and 64-bit platforms.
ci->flag: VM_CALL_* flags only use 9 bits, currently
ci->aux.index: 2 billion ivars per class should be enough for anybody
This saves around 50K allocations on "valgrind ruby -e exit" on x86-64
before:
total heap usage: 48,122 allocs, 19,253 frees, 8,099,197 bytes allocated
after:
total heap usage: 48,069 allocs, 19,214 frees, 8,047,266 bytes allocated
* vm_core.h (rb_call_info_t): ci->flag becomes 32-bit unsigned int
ci->index becomes a 32-bit signed int (from signed long).
Reorder for better packing on 64-bit, giving an 8 byte reduction
from 104 to 96 bytes for each ci.
* compile.c (new_callinfo, setup_args, iseq_compile_each,
iseq_build_from_ary_body): adjust for type changes
* vm_insnhelper.c (vm_getivar): ditto

Please refer this ticket for details.
This change also introduces the following changes.
* Remove RGENGC_AGE2_PROMOTION and introduce object age (0 to 3).
Age can be count with FL_PROMOTE0 and FL_PROMOTE1 flags in
RBasic::flags (2 bit). Age == 3 objects become old objects.
* WB_PROTECTED flag in RBasic to WB_UNPROTECTED bitmap.
* LONG_LIVED bitmap to represent living objects while minor GCs
It specifies (1) Old objects and (2) remembered shady objects.
* Introduce rb_objspace_t::marked_objects which counts marked
objects in current marking phase. marking count is needed to
introduce incremental marking.
* rename mark related function and sweep related function to
gc_(marks|sweep)_(start|finish|step|rest|continue).
* rename rgengc_report() to gc_report().
* Add obj_info() function to get cstr of object details.
* Add MEASURE_LINE() macro to measure execution time of specific line.
* and many small fixes.
* include/ruby/ruby.h: add flag USE_RINCGC.
Now USE_RINCGC can be set only with USE_RGENGC.
* include/ruby/ruby.h: introduce FL_PROMOTED0 and add FL_PROMOTED1
to count object age.
* include/ruby/ruby.h: rewrite write barriers for incremental marking.
* debug.c: catch up flag name changes.
* internal.h: add rb_gc_writebarrier_remember() instead of
rb_gc_writebarrier_remember_promoted().
* array.c (ary_memcpy0): use rb_gc_writebarrier_remember().
* array.c (rb_ary_modify): ditto.
* hash.c (rb_hash_keys): ditto.
* hash.c (rb_hash_values): ditto.
* object.c (init_copy): use rb_copy_wb_protected_attribute() because
FL_WB_PROTECTED is moved from RBasic::flags.
* test/objspace/test_objspace.rb: catch up ObjectSpace.dump() changes.

* include/ruby/io.h (rb_io_buffer_t): pack structure
Reduces rb_io_t from 200 to 192 bytes, allowing rb_io_t to
occupy one less cache line.
[Feature #10050]
n.b. this leaves a 4-byte hole after the `cbuf' field which may
be used for future expansion.

* include/ruby/io.h (rb_io_t): shrink to 200 bytes from 216 on 64-bit
This puts us within 8 bytes of being three cache lines instead of
four lines on x86-64. This breaks the ABI.
[Feature #10050]

* include/ruby/oniguruma.h (struct re_pattern_buffer): shrink to 448
bytes from 464 bytes on 64-bit. This breaks the ABI.
[Feature #10034]
Reducing struct re_pattern_buffer from 464 to 448 bytes allows it to fit
into neatly into seven 64-byte cache lines on x86-64 systems.

the equality, otherwise the behavior is undefined.

* configure.in (with-jemalloc): also check for header, for ABIs
which JEMALLOC_MANGLE is needed, i.e., Mach-O and PE-COFF
platforms. [ruby-core:62939] [Feature #9113]
* include/ruby/missing.h: include alternative malloc header to
replace memory management functions.
* dln.c, io.c, parse.y, st.c: undef malloc family before
re-definition to suppress warnings.

include/ruby/encoding.h to hide the extra field.

This is too new to be a compatibility problem.
* include/ruby/ruby.h: Hide Symbol internals.
(struct RSymbol): moved to internal.h
(RSYMBOL): ditto
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@46219 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* win32/win32.c (rb_w32_sysinit): use WCHAR version of GetCommandLine()
internally.
* win32/win32.c (w32_cmdvector): renamed from rb_w32_cmdvector. use
WCHAR* instead of char* internally.
these changes are expected to not changing the behavior yet.

See this ticket about Symbol GC.
* include/ruby/ruby.h:
Declare few functions.
* rb_sym2id: almost same as old SYM2ID but support dynamic symbols.
* rb_id2sym: almost same as old ID2SYM but support dynamic symbols.
* rb_sym2str: almost same as `rb_id2str(SYM2ID(sym))` but not
pin down a dynamic symbol.
Declare a new struct.
* struct RSymbol: represents a dynamic symbol as object in
Ruby's heaps.
Add few macros.
* STATIC_SYM_P: check a static symbol.
* DYNAMIC_SYM_P: check a dynamic symbol.
* RSYMBOL: cast to RSymbol
* gc.c: declare RSymbol. support T_SYMBOL.
* internal.h: Declare few functions.
* rb_gc_free_dsymbol: free up a dynamic symbol. GC call this
function at a sweep phase.
* rb_str_dynamic_intern: convert a string to a dynamic symbol.
* rb_check_id_without_pindown: not pinning function.
* rb_sym2id_without_pindown: ditto.
* rb_check_id_cstr_without_pindown: ditto.
* string.c (Init_String): String#intern and String#to_sym use
rb_str_dynamic_intern.
* template/id.h.tmpl: use LSB of ID as a flag for determining a
static symbol, so we shift left other ruby_id_types.
* string.c: use rb_sym2str instead `rb_id2str(SYM2ID(sym))` to
avoid pinning.
* load.c: use xx_without_pindown function at creating temporary ID
to avoid pinning.
* object.c: ditto.
* sprintf.c: ditto.
* struct.c: ditto.
* thread.c: ditto.
* variable.c: ditto.
* vm_method.c: ditto.

constify a parameter (VALUE *).
I believe this incompatibility doesn't break any code.
However, if you have trouble, please tell us.
* eval.c, object.c: ditto.

* include/ruby/win32.h, win32/win32.c (rb_w32_inet_pton): add a
wrapper function for inet_pton minimum supported client is
Vista, as well as inet_ntop.

* include/ruby/ruby.h (RB_GC_GUARD):
use rb_gc_guarded_ptr_val on non-GCC/MSC
* gc.c (rb_gc_guarded_ptr_val): rename and adjust argument.
RB_GC_GUARD should be robust enough for any compiler.
