2012-09-08internal.h: allocator function in rb_classext_tnobu
* internal.h (struct rb_classext_struct): move allocator function into rb_classext_t from ordinary method table. [ruby-dev:46121] [Feature #6993] * object.c (rb_obj_alloc): call allocator function directly. * vm_method.c (rb_define_alloc_func, rb_undef_alloc_func) (rb_get_alloc_func): use allocator function in rb_classext_t. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36925 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2012-06-15* vm_core.h: remove VM_FRAME_MAGIC_FINISH (finish frame type).ko1
Before this commit: `finish frame' was place holder which indicates that VM loop needs to return function. If a C method calls a Ruby methods (a method written by Ruby), then VM loop will be (re-)invoked. When the Ruby method returns, then also VM loop should be escaped. `finish frame' has only one instruction `finish', which returns VM loop function. VM loop function executes `finish' instruction, then VM loop function returns itself. With such mechanism, `leave' instruction (which returns one frame from current scope) doesn't need to check that this `leave' should also return from VM loop function. Strictly, one branch can be removed from `leave' instructon. Consideration: However, pushing the `finish frame' needs costs because it needs several memory accesses. The number of pushing `finish frame' is greater than I had assumed. Of course, pushing `finish frame' consumes additional control frame. Moreover, recent processors has good branch prediction, with which we can ignore such trivial checking. After this commit: Finally, I decide to remove `finish frame' and `finish' instruction. Some parts of VM depend on `finish frame', so the new frame flag VM_FRAME_FLAG_FINISH is introduced. If this frame should escape from VM function loop, then the result of VM_FRAME_TYPE_FINISH_P(cfp) is true. `leave' instruction checks this flag every time. I measured performance on it. However on my environments, it improves some benchmarks and slows some benchmarks down. Maybe it is because of C compiler optimization parameters. I'll re-visit here if this cause problems. * insns.def (leave, finish): remove finish instruction. * vm.c, vm_eval.c, vm_exec.c, vm_backtrace.c, vm_dump.c: apply above changes. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36099 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-06-11 * compile.c (iseq_set_sequence): nonstatic initializer of anshyouhei
aggregate type is a C99ism. * compile.c (enum compile_array_type_t): comma at the end of enum list is a C99ism. * vm_backtrace.c (enum LOCATION_TYPE): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36029 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-06-08* remove trailing spaces.nobu

2012-06-04* vm_core.h (rb_location_t): fix type and field name.ko1
(1) rename rb_location_t to rb_iseq_location_t. (2) rename field names of rb_iseq_location_t to adjust RubyVM::Backtrace::Location methods. (2-1) filename -> path (2-2) filepath -> absolute_path (2-3) basename -> base_label (2-4) name -> label (3) rename filed name rb_iseq_location_t#line_no to rb_iseq_location_t#first_lineno to clear purpose of this field. (4) The field names rb_binding_t#(filename|line_no) are also renamed to rb_binding_t#(path|first_lineno). * compile.c: apply above changes. * iseq.c: ditto. * proc.c: ditto. * vm*.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@35899 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-06-02* vm_backtrace.c: change names.ko1
(1) Class name: RubyVM::FrameInfo -> RubyVM::Backtrace::Location. (2) Method name: RubyVM::FrameInfo.caller -> Kernel.caller_locations. (3) Instance methods of RubyVM::FrameInfo (RubyVM::Backtrace::Location) (3-1) name -> label (3-2) basename -> base_label (basename is confusing with File.basename) (3-3) line_no -> lineno (We have already similar name File#lineno, commented by kou [ruby-dev:45686]). (3-4) filename -> path. (3-5) filepath -> absolute_path. (3-5) iseq -> removed (we will make other APIs to access iseq and other information of frame for debugging). * test/ruby/test_backtrace.rb: apply above changes. And apply comment from kou [ruby-dev:45686]. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@35873 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-06-02* common.mk: fix to build vm_backtrace.c only itself (vm_backtrace.cko1
is no longer included from vm.c). I hope this separation reduce compile time of vm.c. * internal.h: ditto. * vm.c, vm_core.h, vm_dump.c, vm_eval.c: ditto. * vm_eval.c: some functions (callee, etc) moved to vm_backtrace.c. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@35871 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2012-06-02* vm_backtrace.c: added. Separate backtrace related functions toko1
this file. * vm.c, common.mk: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@35868 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
