* * iseq.c, vm_eval.c: set th->base_block properly.ko12012-06-221-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* * vm_core.h: remove VM_FRAME_MAGIC_FINISH (finish frame type).ko12012-06-151-37/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* * vm_core.h: remove lfp (local frame pointer) and renameko12012-06-111-92/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

(2) remove rb_backtrace_each(). Use backtrace_each() instead.

RubyVM::Backtrace object is lightweight backtrace information, which contains complete information to generate traditional style backtrace (an array of strings) with faster generation. If someone accesses to backtrace information via Exception#backtrace, then convert a RubyVM::Backtrace object to traditonal style backtrace.

| | | | | | | | | | | | | | | | fixes: Bug #2729 a patch from Kazuki Tsujimoto <kazuki@callcc.net> This problem is caused by changing dfp (dynamic env pointer) from saved dfp. Saved dfp is pointed env in VM stack. However, the dfp can be moved because VM copies env from VM stack to the heap. At this copying, dfp was also changed. To solve this problem, I'll try to change throw mechanism (not save target dfp, but save target cfp). * bootstraptest/test_flow.rb: add a test for above. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@33064 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | | | | | | | | | | | to solve an issue reported at [ruby-dev:44413] [Ruby 1.9 - Bug #5217]. Before this fix, each instruction has an information including line number (iseq::iseq_insn_info_table). Instead of this data structure, recording only line number changing places (iseq::iseq_line_info_table). The order of entries in iseq_line_info_table is ascending order of iseq_line_info_table_entry::position. You can get a line number by an iseq and a program counter with this data structure. This fix reduces memory consumption of iseq (bytecode). On my measurement, a rails application consumes 21.8MB for iseq with this fix on the 32bit CPU. Without this fix, it consumes 24.7MB for iseq [ruby-dev:44415]. * proc.c: ditto. * vm_insnhelper.c: ditto. * vm_method.c: ditto. * vm.c (rb_vm_get_sourceline): change to use rb_iseq_line_no(). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@33046 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
