* inline Primitive.cexpr!卜部昌平2020-07-131-0/+12
| | | | | We can obtain the verbatim source code of Primitive.cexpr!. Why not paste that content into the JITed program.
* add UNREACHABLE_RETURN卜部昌平2020-06-291-0/+1
| | | | | | Not every compilers understand that rb_raise does not return. When a function does not end with a return statement, such compilers can issue warnings. We would better tell them about reachabilities.
* fix_pow: do not goto into a branch卜部昌平2020-06-291-31/+26
| | | | | I'm not necessarily against every goto in general, but jumping into a branch is definitely a bad idea. Better refactor.

* Mark some Integer methods as inline (#3264)Takashi Kokubun2020-06-271-73/+0

* Make Integer#zero? a separated method and builtin (#3226)Takashi Kokubun2020-06-201-7/+17
| | | | | | | A prerequisite to fix https://bugs.ruby-lang.org/issues/15589 with JIT. This commit alone doesn't make a significant difference yet, but I thought this commit should be committed independently. This method override was discussed in [Misc #16961].
* Remove unused else if statements in int_even_p func (#3220)S.H2020-06-161-10/+6
| | | | | | | * remove else if & rb_funcall * fix int_even_p impl * fix rb_int_odd_p implementation
* Add static modifier for rb_int_ceil & rb_int_floor (#3217)S.H2020-06-161-4/+4

* numeric.c: optimize `float ** 2` case by fastpathYusuke Endoh2020-05-121-1/+5
| | | | | | It would be a relatively frequent case. It is still slower than `float * float` because `*` has a dedicated VM instruction (opt_mult), though.
* sed -i 's|ruby/impl|ruby/internal|'卜部昌平2020-05-111-1/+1
| | | | To fix build failures.
* sed -i s|ruby/3|ruby/impl|g卜部昌平2020-05-111-1/+1
| | | | This shall fix compile errors.

* numeric.c: Remove unreachable codeYusuke Endoh2020-04-091-4/+1

* Check the encoding of `half:` optionNobuyoshi Nakada2020-01-271-0/+1

* decouple internal.h headers卜部昌平2019-12-261-4/+18
| | | | | | | | | | | | | | | | | | Saves comitters' daily life by avoid #include-ing everything from internal.h to make each file do so instead. This would significantly speed up incremental builds. We take the following inclusion order in this changeset: 1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very first thing among everything). 2. RUBY_EXTCONF_H if any. 3. Standard C headers, sorted alphabetically. 4. Other system headers, maybe guarded by #ifdef 5. Everything else, sorted alphabetically. Exceptions are those win32-related headers, which tend not be self- containing (headers have inclusion order dependencies).
* add several __has_something macro卜部昌平2019-12-261-11/+11
| | | | | | | With these macros implemented we can write codes just like we can assume the compiler being clang. MSC_VERSION_SINCE is defined to implement those macros, but turned out to be handy for other places. The -fdeclspec compiler flag is necessary for clang to properly handle __has_declspec().
* make functions static卜部昌平2019-11-191-3/+4
| | | | | | | These functions are used from within a compilation unit so we can make them static, for better binary size. This changeset reduces the size of generated ruby binary from 26,590,128 bytes to 26,584,472 bytes on my macihne.
* Use FIX2LONG instead of FIX2INT like 26843cbcd0NARUSE, Yui2019-11-071-4/+4
|
* Use FIX2LONG to avoid unexpected exceptionNARUSE, Yui2019-11-071-1/+1
| | | | | Though it won't happen in the real world in this context, FIX2INT may raise an exception and it cause to generate extra code.
* Suppress keyword argument warning from #stepNobuyoshi Nakada2019-09-301-1/+1
| | | | | | * numeric.c (num_step): pass the extracted argument from keyword argument, not the last argument itself which should have been warned already.
* Inspect dynamic symbol as well as static symbolNobuyoshi Nakada2019-08-251-1/+1
|
* Expanded f_quoNobuyoshi Nakada2019-08-101-3/+3

* Prefer `rb_error_arity` to `rb_check_arity` when it can be usedYusuke Endoh2019-07-141-2/+1
|
* Make opt_aref instruction support Integer#[]Yusuke Endoh2019-06-011-3/+3
| | | | | | | | | | | | only when its receiver and the argument are both Integers. Since 6bedbf4625, Integer#[] has supported a range extraction. This means that Integer#[] now accepts multiple arguments, which made the method very slow unfortunately. This change fixes the performance issue by adding a special handling for its traditional use case: `num[idx]` where both `num` and `idx` are Integers.
