2017-09-05add rb_hash_new_with_size()shyouhei
Sometimes, size of a hash can be calcluated a priori. By providing such info to the constructor we can avoid unnecessary internal re- allocations. This can boost for instance creation of hash literals.

2017-04-21refactor hash literalshyouhei
Same as rb_ary_tmp_new_from_values(), it reduces vm_exec_core binary size from 26,176 bytes to 26,080 bytes. But this time, also with a bit of optimizations: - Because we are allocating a new hash and no back references are introduced at all, we can safely skip write barriers. - Also, the iteration never recurs. We can avoid complicated function callbacks by using st_insert instead of st_update. ---- * hash.c (rb_hash_new_from_values): refactor extract the bulk insert into a function. * hash.c (rb_hash_new_from_object): also refactor. * hash.c (rb_hash_s_create): use the new functions. * insns.def (newhash): ditto. * vm.c (core_hash_from_ary): ditto. * iternal.h: export the new function. ----------------------------------------------------------- benchmark results: minimum results in each 7 measurements.

2017-04-18split insns.def into functionsshyouhei
Contemporary C compilers are good at function inlining. They fold multiple functions into one. However they are not yet smart enough to unfold a function into several ones. So generally speaking, it is wiser for a C programmer to manually split C functions whenever possible. That should make rooms for compilers to optimize at will. Before this changeset insns.def was converted into single HUGE function called vm_exec_core(). By moving each instruction's core into individual functions, generated C source code is reduced from 3,428 lines to 2,847 lines. Looking at the generated assembly however, it seems my compiler (gcc 6.2) is extraordinary smart so that it inlines almost all functions I introduced in this changeset back into that vm_exec_core. On my machine compiled machine binary of the function does not shrink very much in size (28,432 bytes to 26,816 bytes, according to nm(1)). I believe this change is zero-cost. Several benchmarks I exercised showed no significant difference beyond error mergin. For instance 3 repeated runs of optcarrot benchmark on my machine resulted in: before this: 28.330329285707490, 27.513378371065920, 29.40420215754537 after this: 27.107195867280414, 25.549324021385907, 30.31581919050884 in fps (greater==faster). ---- * internal.h (rb_obj_not_equal): used from vm_insnhelper.c * insns.def: move vast majority of lines into vm_insnhelper.c * vm_insnhelper.c: moved here. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58390 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-03-06optimize FIXABLE macroshyouhei
Looking at the source code, FIXABLE tends to be just before LOING2FIX to check applicability of that operation. Why not try computing first then check for overflow, which should be optimial. I also tried the same thing for unsigned types but resulted in slower execution. It seems RB_POSFIXABLE() is fast enough on modern CPUs. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57789 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-02-02Use carry flag to reduce instructionsnaruse
NOTE: (1) Fixnum's LSB is always 1. It means you can always run `x - 1` without overflow. (2) Of course `z = x + (y-1)` may overflow. Now z's LSB is always 1, and the MSB of true result is also 1. You can get true result in long as `(1<<63)|(z>>1)`, and it equals to `(z<<63)|(z>>1)` == `ror(z)`.

Infinity cannot be written as an optimizable literal, so it can never match a key in a CDHASH.

2015-12-08* introduce new ISeq binary format serializer/de-serializerko1
and a pre-compilation/runtime loader sample. [Feature #11788] * iseq.c: add new methods: * RubyVM::InstructionSequence#to_binary_format(extra_data = nil) * RubyVM::InstructionSequence.from_binary_format(binary) * RubyVM::InstructionSequence.from_binary_format_extra_data(binary) * compile.c: implement body of this new feature. * load.c (rb_load_internal0), iseq.c (rb_iseq_load_iseq): call RubyVM::InstructionSequence.load_iseq(fname) with loading script name if this method is defined. We can return any ISeq object as a result value. Otherwise loading will be continue as usual. This interface is not matured and is not extensible. So that we don't guarantee the future compatibility of this method. Basically, you should'nt use this method. * iseq.h: move ISEQ_MAJOR/MINOR_VERSION (and some definitions) from iseq.c. * encoding.c (rb_data_is_encoding), internal.h: added. * vm_core.h: add several supports for lazy load. * add USE_LAZY_LOAD macro to specify enable or disable of this feature. * add several fields to rb_iseq_t. * introduce new macro rb_iseq_check(). * insns.def: some check for lazy loading feature. * vm_insnhelper.c: ditto. * proc.c: ditto. * vm.c: ditto. * test/lib/iseq_loader_checker.rb: enabled iff suitable environment variables are provided. * test/runner.rb: enable lib/iseq_loader_checker.rb. * sample/iseq_loader.rb: add sample compiler and loader. $ ruby sample/iseq_loader.rb [dir] will compile all ruby scripts in [dir]. With default setting, this compile creates *.rb.yarb files in same directory of target .rb scripts. $ ruby -r sample/iseq_loader.rb [app] will run with enable to load compiled binary data. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@52949 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
