- remove blockinlining.$(OBJEXT) to built - make ENCODING_H_INCLDUES variable (include/ruby/encoding.h) - make VM_CORE_H_INCLUDES variable (vm_core.h) - simplify rules. - make depends rule to output depend status using gcc -MM. * include/ruby/mvm.h, include/ruby/vm.h: rename mvm.h to vm.h. * include/ruby.h: ditto. * load.c: add inclusion explicitly. * enumerator.c, object.c, parse.y, thread.c, vm_dump.c: remove useless inclusion. * eval_intern.h: cleanup inclusion. * vm_core.h: rb_thread_t should be defined in this file. * vm_evalbody.c, vm_exec.c: rename vm_evalbody.c to vm_exec.c. * vm.h, vm_exec.h: rename vm.h to vm_exec.h. * insnhelper.h, vm_insnhelper.h: rename insnhelper.h to vm_insnhelper.h. * vm.c, vm_insnhelper.c, vm_insnhelper.h: - rename vm_eval() to vm_exec_core(). - rename vm_eval_body() to vm_exec(). - cleanup include order. * vm_method.c: fix comment. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@19466 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
