Yusuke Endoh 42abad2464 numeric.c: optimize `float ** 2` case by fastpath 
It would be a relatively frequent case.  It is still slower than
`float * float` because `*` has a dedicated VM instruction (opt_mult),
though.

卜部昌平 5e22f873ed decouple internal.h headers 
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).
 2019-12-26 20:45:12 +09:00
卜部昌平 0958e19ffb add several __has_something macro 
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().
 2019-12-26 20:45:12 +09:00
卜部昌平 0e8219f591 make functions static 
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.

Yusuke Endoh 65e63af377 Make opt_aref instruction support Integer#[] 
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.

shyouhei b8540e0a9d numeric.c: avoid division by zero 
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.  But that is not
possible today.
