| | | | | | | | | | | | | | | | | Debugging/profiling features will be located. * vm_trace.c: expose C-level TracePoint APIs. Note that they are experimental. * vm_trace.c, include/ruby/debug.h: rename `rb_hook_flag_t' to `rb_event_hook_flag_t'. Macro names `RUBY_HOOK_FLAG_*' are also renamed to `RUBY_EVENT_HOOK_FLAG_*'. * debug.h, vm_debug.h: rename debug.h to vm_debug.h. * common.mk: ditto. * debug.c, main.c, vm_core.h: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37765 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* Fix build when gcc is used and the platform's libc lacks alloca().knu2012-11-091-4/+17
| | | | | | | | | | | | | | | | * include/ruby/ruby.h (alloca), eval_intern.h (alloca), gc.c (alloca): Make alloca() globally available by moving the ultimate ifdef's to ruby/ruby.h. Gcc hides its builtin alloca() when compiling with -ansi, and linking thus fails on platforms that lack their own alloca() implementation in libc, which include OpenBSD and some ports of NetBSD. We use alloca() everywhere including from within third party C extentions, so alloca() must be made globally available.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 64bit CPU environment (sizeof(double) == sizeof(VALUE)). flonum technique enables to avoid double object creation if the double value d is in range about between 1.72723e-77 < |d| <= 1.15792e+77 or 0.0. flonum Float value is immediate and their lowest two bits are b10. If flonum is activated, then USE_FLONUM macro is 1. I'll write detailed in this technique on https://bugs.ruby-lang.org/projects/ruby-trunk/wiki/Flonum_tech * benchmark/bmx_temp.rb: add an benchmark for simple Float calculation. * gc.c (id2ref, rb_obj_id): add flonum Float support. * include/ruby/intern.h: move decl of rb_float_new(double) to include/ruby/ruby.h. * insns.def, vm.c, vm_insnhelper.c: add flonum optimization and simplify source code. * vm_insnhelper.h (FLONUM_2_P): added. * marshal.c: support flonum output. * numeric.c (rb_float_new_in_heap): added. * parse.y: support flonum. * random.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36798 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (1) add rb_hook_list_t data structure which includes hooks, events (flag) and `need_clean' flag. If the last flag is true, then clean the hooks list. In other words, deleted hooks are contained by `hooks'. Cleanup process should run before traversing the list. (2) Change check mechanism See EXEC_EVENT_HOOK() in vm_core.h. (3) Add `raw' hooks APIs Normal hooks are guarded from exception by rb_protect(). However, this protection is overhead for too simple functions which never cause exceptions. `raw' hooks are executed without protection and faster. Now, we only provide registration APIs. All `raw' hooks are kicked under protection (same as normal hooks). * include/ruby/ruby.h: remove internal data definition and macros. * internal.h (ruby_suppress_tracing), vm_trace.c: rename ruby_suppress_tracing() to rb_suppress_tracing() and remove unused function parameter. * parse.y: fix to use renamed rb_suppress_tracing(). * thread.c (thread_create_core): no need to set RUBY_VM_VM. * vm.c (mark_event_hooks): move definition to vm_trace.c. * vm.c (ruby_vm_event_flags): add a global variable.
