2017-03-07Use ADD instead of MULnaruse
* 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. ADD and JO is much smaller though it is also Macro-Fusion unfriendly. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57793 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-03-06optimize FIXABLE macroshyouhei
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
