2012-12-17* method.h: remove `VM_METHOD_TYPE_CFUNC_FRAMELESS' method type.ko1
This method type is for optimized CFUNC such as Fixnum#+ and so on. This feature is half-baked and no way to use them. [Background] Now, VM has opt_plus instructions to optimize `+' methods for some Classes (such as Fixnum, Float (flonum)). We call this type of instructions as `specialized instructions'. This simple technique improve simple program dramatically. However, we can make specialized instructions for only several types (classes) and selectors (method names) because a large instruction will be slow. In other words, this technique has no extensibility. To overcome this problem, VM_METHOD_TYPE_CFUNC_FRAMELESS was introduced (r37198). This type is a variant of CFUNC, but called their functiions directly without building a method frame. Any CFUNC method can be defined as frameless methods if a method is not needed to make method frame. Frameless methods are faster as specialized instructions (a bit slower, but no need to care). No problem described at http://charlie.bz/blog/why-do-singleton-methods-make-ruby-slow because this technique doesn't see class, but see method body itself. Alias is also no problem. [Problem] However, we can't set frameless method type for polymorphic methods such as Array#[]. Necessity for method frame depends on which parameter type. For example, Fixnum#+ needs method frame if coerce is needed. Current VM_METHOD_TYPE_CFUNC_FRAMELESS is not flexible and need more tuning to introduce it. Expected behavior of frameless method type may be: result = optimized_cfunc(params); /* call optimized cfunc */ if (result == Qundef) { result = normal_cfunc(); } This is why I say this feature is half-baked. We need to learn primitive method in Smalltalk more. (I heard this name at RubyConf Taiwan this month. Thanks!) [Conclusion] Nobody may use this feature and there is no compatibility issue. This feature goes to next minor (2.1?). * proc.c (rb_method_entry_arity): ditto. * vm_eval.c, vm_insnhelper.c, vm_method.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38431 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2012-12-06* revised r37993 to avoid SEGV/ILL in tests. In r37993, a methodshugo
entry with VM_METHOD_TYPE_REFINED holds only the original method definition, so ci->me is set to a method entry allocated in the stack, and it causes SEGV/ILL. In this commit, a method entry with VM_METHOD_TYPE_REFINED holds the whole original method entry. Furthermore, rb_thread_mark() is changed to mark cfp->klass to avoid GC for iclasses created by copy_refinement_iclass(). * vm_method.c (rb_method_entry_make): add a method entry with VM_METHOD_TYPE_REFINED to the class refined by the refinement if the target module is a refinement. When a method entry with VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with the same name is searched in refinements. If such a method is found, the method is invoked. Otherwise, the original method in the refined class (rb_method_definition_t::body.orig_me) is invoked. This change is made to simplify the normal method lookup and to improve the performance of normal method calls. * vm_method.c (EXPR1, search_method, rb_method_entry), vm_eval.c (rb_call0, rb_search_method_entry): do not use refinements for method lookup. * vm_insnhelper.c (vm_call_method): search methods in refinements if ci->me is VM_METHOD_TYPE_REFINED. If the method is called by super (i.e., ci->call == vm_call_super_method), skip the same method entry as the current method to avoid infinite call of the same method. * class.c (include_modules_at): add a refined method entry for each method defined in a module included in a refinement. * class.c (rb_prepend_module): set an empty table to RCLASS_M_TBL(klass) to add refined method entries, because refinements should have priority over prepended modules. * proc.c (mnew): use rb_method_entry_with_refinements() to get a refined method. * vm.c (rb_thread_mark): mark cfp->klass for iclasses created by copy_refinement_iclass(). * vm.c (Init_VM), cont.c (fiber_init): initialize th->cfp->klass. * test/ruby/test_refinement.rb (test_inline_method_cache): do not skip the test because it should pass successfully. * test/ruby/test_refinement.rb (test_redefine_refined_method): new test for the case a refined method is redefined. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38236 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2012-10-23* vm_core.h, vm_insnhelper.c, vm_eval.c (OPT_CALL_CFUNC_WITHOUT_FRAME):ko1
add a new otpimization and its macro `OPT_CALL_CFUNC_WITHOUT_FRAME'. This optimization makes all cfunc method calls `frameless', which is fster than ordinal cfunc method call. If `frame' is needed (for example, it calls another method with `rb_funcall()'), then build a frame. In other words, this optimization delays frame building. However, to delay the frame building, we need additional overheads: (1) Store the last call information. (2) Check the delayed frame buidling before the frame is needed. (3) Overhead to build a delayed frame. rb_thread_t::passed_ci is storage of delayed cfunc call information. (1) is lightweight because it is only 1 assignment to `passed_ci'. To achieve (2), we modify GET_THREAD() to check `passed_ci' every time. It causes 10% overhead on my envrionment. This optimization only works for cfunc methods which do not need their `frame'. After evaluation on my environment, this optimization does not effective every time. Because of this evaluation results, this optimization is disabled at default. * vm_insnhelper.c, vm.c: add VM_PROFILE* macros to measure behaviour of VM internals.

2012-06-22* iseq.c, vm_eval.c: set th->base_block properly.ko1
th->base_block is information for (a) parsing, (b) compiling and (c) setting up the frame to execute the program passed by `eval' method. For example, (1) parser need to know up-level variables to detect it is variable or method without paren. Befor (a), (b) and (c), VM set th->base_block by passed bindng (or previous frame information). After execute (a), (b) and (c), VM should clear th->base_block. However, if (a), (b) or (c) raises an exception, then th->base_block is not cleared. Problem is that the uncleared value th->balo_block is used for irrelevant iseq compilation. It causes SEGV or critical error. I tried to solve this problem: to clear them before exception, but finally I found out that it is difficult to do it (Ruby program can be run in many places). Because of this background, I set th->base_block before compiling iseq and restore it after compiling. Basically, th->base_block is dirty hack (similar to global variable) and this patch is also dirty. * bootstraptest/test_eval.rb: add a test for above. * internal.h: remove unused decl. * iseq.c (rb_iseq_compile_with_option): add base_block parameter. set th->base_block before compation and restore it after compilation. * ruby.c (require_libraries): pass 0 as base_block instead of setting th->base_block * tool/compile_prelude.rb (prelude_eval): apply above changes. * vm.c, vm_eval.c: ditto. * vm_core.h: add comments. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36179 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* vm_core.h: remove lfp (local frame pointer) and renameko1
dfp (dynamic frame pointer) to ep (environment pointer). This change make VM `normal' (similar to other interpreters). Before this commit: Each frame has two env pointers lfp and dfp. lfp points local environment which is method/class/toplevel frame. lfp[0] is block pointer. dfp is block local frame. dfp[0] points previous (parent) environment pointer. lfp == dfp when frame is method/class/toplevel. You can get lfp from dfp by traversing previous environment pointers. After this commit: Each frame has only `ep' to point respective enviornoment. If there is parent environment, then ep[0] points parent envioenment (as dfp). If there are no more environment, then ep[0] points block pointer (as lfp). We call such ep as `LEP' (local EP). We add some macros to get LEP and to detect LEP or not. In short, we replace dfp and lfp with ep and LEP. rb_block_t and rb_binding_t member `lfp' and `dfp' are removed and member `ep' is added. rename rb_thread_t's member `local_lfp' and `local_svar' to `root_lep' and `root_svar'. (VM_EP_PREV_EP(ep)): get previous environment pointer. This macro assume that ep is not LEP. (VM_EP_BLOCK_PTR(ep)): get block pointer. This macro assume that ep is LEP. (VM_EP_LEP_P(ep)): detect ep is LEP or not. (VM_ENVVAL_BLOCK_PTR(ptr)): make block pointer. (VM_ENVVAL_BLOCK_PTR_P(v)): detect v is block pointer.
