| | | | | | | | | | | | | | | | | | | Defining PACKED_STRUCT_UNALIGNED to a noop in ruby/config.h (via `configure') prevents the definition in include/ruby/defines.h from working This should have been fixed in r46914, so there's a size regression for some objects since Ruby 2.2+. I do not believe we can backport to existing releases, either, since it can affect ABI.

* fix --with-gmp (broken by r57490)shyouhei2017-04-051-2/+4
| | | | | | | | | | | Looking at the generated shell script (also the autoconf manual), it seems AC_SEARCH_LIBS() m4 macro does not define HAVE_LIBsomething C preprocessor macros, unlike AC_CHECK_LIB() which does define them. This previous change effectively killed building with GMP because building that mode depends on existence of HAVE_LIBGMP.

| | | | | | | | | | | | | | | | | These methods are useful for safe/concurrent file I/O in multi-thread/process environments and also fairly standard nowadays especially in systems supporting pthreads. Based on patches by Avseyev <sergey.avseyev@gmail.com> at [ruby-core:79290]. [Feature #4532] * configure.in: check for pwrite(2). pread() is already used internally for IO.copy_stream. * io.c: implement wrappers for pread(2) and pwrite(2) and expose them in IO. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58240 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* use HAVE_BUILTIN___BUILTIN_MUL_OVERFLOWshyouhei2017-03-061-0/+1
| | | | | | | | | | | | | | | | | | | We already check for __builtin_mul_overflow in configure but never actually referred it before. Why not call it if available, because that should render supposedly-optimial assembly outputs. Optionally if __builtin_mul_overflow_p is available, which is the case for recent GCC, use that to detect fixnum overflow. This is much faster than the previous. On my machine generated assembly of numeric.c:int_pow reduces from 480 to 448 bytes, according to nm(1). Also on my machine, following script boosts from 7.819 to 6.929 sec. time ./miniruby -e 'i=0; while i < 30_000_000 do i += 1; 7 ** 23; end' Signed-off-by: Urabe, Shyouhei <shyouhei@ruby-lang.org> git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57784 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* Use carry flag to reduce instructionsnaruse2017-02-021-0/+3
| | | | | | | | | | | | | | | | 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)`.
