* refactor extract binop dispatchershyouhei2017-04-191-171/+107
| | | | | | | | | | | | | | | | | | | | | | Those opt_something instructions are worth refactoring. They tend to have similar ways of executions. By extracting the common part, generated vm_exec_core function shrinks from 26,816 bytes to 26,256 bytes (according to nm(1)). This changeset introduces negligible performance impact. 3 repeated runs of optcarrot benchmark on my machine resulted in: before this: 28.813363684823557, 27.523907198440366, 27.292766121965400 after this: 28.174038497265080, 28.999513875020405, 29.621399800428065 in fps (greater==faster). ---- * vm_insnhelper.c (vm_opt_binop_dispatch): new function. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58402 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* split insns.def into functionsshyouhei2017-04-181-0/+866
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | define as `static inline` when it is not optimized to keep the symbol generated. * vm_insnhelper.c (vm_getivar): use `INLINE` to force inline so that a compiler inlines it into vm_getinstancevariable and optimizes out is_attr and related branches. * vm_insnhelper.c (vm_getivar): use `inline` to recommend inline.
