* re-introduce __builtin_add_overflowshyouhei2017-03-083-25/+20
| | | | | | | | | | | | | r57789 (74cdd89) was gradually "improve"d by naruse through r57793 to r57806, resulted in reverting the efect of r57789 while retaining its complexity. I think the current situation is slightly worse than before (same output complicated source code). Here I introduce __builtin_add_overflow again, which (I think) is what naruse wanted to do in r57793. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57807 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | | | | * On recent CPUs, 2-operand MUL's latency is 3 cycle but ADD is 1 cycle. * clang Optimizes `MUL rax,2` into `ADD rax,rax` but gcc7 doesn't. * LONG2FIX is compiled into `lea r14,[r15+r15*1+0x1]`; this is 1cycle and run in parallel if the branch prediction is correct. * Note that old (RB_POSFIXABLE(f) && RB_NEGFIXABLE(f)) is usually uses following instructions. * movabs rax,0x4000000000000000 * add rax,rdi * js It needs large immediate and Macro-Fusion is not applied.

* optimize FIXABLE macroshyouhei2017-03-068-42/+71
| | | | | | | | | | | | Looking at the source code, FIXABLE tends to be just before LOING2FIX to check applicability of that operation. Why not try computing first then check for overflow, which should be optimial. I also tried the same thing for unsigned types but resulted in slower execution. It seems RB_POSFIXABLE() is fast enough on modern CPUs. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57789 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* use HAVE_BUILTIN___BUILTIN_MUL_OVERFLOWshyouhei2017-03-063-4/+32
| | | | | | | | | | | | | | | | | | | 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
