* 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.

| | | | 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.

* 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.

|
* 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.

| | | | | | | | | | | | | | | | | | | In C, division by zero is undefined, even if the expression is double (cf: ISO/IEC 9899:1990 section 6.3.5). OTOH we have tests about such operations and results, means we expect no exceptional situation shall occur. We need to carefully reroute the situation, and generate what is needed. See also: https://travis-ci.org/ruby/ruby/jobs/452680646#L2943 PS: Recently (last two decades), C have Annex. F document. It normatively specifies that the division operator is IEEE 754's division operator (cf: ISO/IEC 9899:1999 section F.3). If we could move to such newer version this could be no problem.
