merge revision(s) 57410,57619,57621,57631,57634: [Backport #13150]
Prevent GC by volatile [Bug #13150]
test/ruby/test_marshal.rb test_context_switch (load) and test_gc (dump)
are failed on FreeBSD 10.3 and gcc7 (FreeBSD Ports Collection) 7.0.0
20170115 (experimental); RB_GC_GUARD looks not worked well.
ruby.h: RB_GC_GUARD stronger than gcc7
* include/ruby/ruby.h (RB_GC_GUARD): prevent guarded pointer from
optimization by using as an input to inline asm.
ruby.h: remove comment
* include/ruby/ruby.h (RB_GC_GUARD): remove comment unsupported by
Solaris AS.
marshal.c: use hidden objects to allow recycling
Hidden objects (klass == 0) are not visible to Ruby code invoked
from other threads or signal handlers, so they can never be
accessed from other contexts. This makes it safe to call
rb_gc_force_recycle on the object slot after releasing malloc
memory.
* marshal.c (rb_marshal_dump_limited): hide dump_arg and recycle when done
(rb_marshal_load_with_proc): hide load_arg and recycle when done
[ruby-core:79518]
marshal.c: revert r57631 partially
* marshal.c (rb_marshal_dump_limited): do not free dump_arg, which
may be dereferenced in check_dump_arg due to continuation, and
get rid of dangling pointers.
* marshal.c (rb_marshal_load_with_proc): ditto for load_arg.
