2021-11-18Optimize dynamic string interpolation for symbol/true/false/nil/0-9Jeremy Evans
This provides a significant speedup for symbol, true, false, nil, and 0-9, class/module, and a small speedup in most other cases. Speedups (using included benchmarks): :symbol :: 60% 0-9 :: 50% Class/Module :: 50% nil/true/false :: 20% integer :: 10% [] :: 10% "" :: 3% One reason this approach is faster is it reduces the number of VM instructions for each interpolated value. Initial idea, approach, and benchmarks from Eric Wong. I applied the same approach against the master branch, updating it to handle the significant internal changes since this was first proposed 4 years ago (such as CALL_INFO/CALL_CACHE -> CALL_DATA). I also expanded it to optimize true/false/nil/0-9/class/module, and added handling of missing methods, refined methods, and RUBY_DEBUG. This renames the tostring insn to anytostring, and adds an objtostring insn that implements the optimization. This requires making a few functions non-static, and adding some non-static functions. This disables 4 YJIT tests. Those tests should be reenabled after YJIT optimizes the new objtostring insn.

2021-08-18rb_fix2uint should use FIXNUM_NEGATIVE_PJohn Hawthorn
rb_num_negative_int_p is equivalent to calling the "<" method on Integer (and checking whether it is overridden), where in this case we are interested in whether the "actual" value can fit inside an unsigned int. This also was slow because rb_num_negative_int_p calls rb_method_basic_definition_p, doing a method lookup to check for < being overridden. This replaces the check in both rb_fix2uint and rb_fix2ushort with FIXNUM_NEGATIVE_P which simply checks whether the VALUE is signed.

2021-08-06Use Rational for Float#round with ndigits > 14Jeremy Evans
ndigits higher than 14 can result in values that are slightly too large due to floating point limitations. Converting to rational for the calculation and then back to float fixes these issues.

2021-07-27Make Float#floor with ndigits argument handle errorJeremy Evans
The previous implementation could result in a returned float that is 1/(10**ndigits) too low. First try adding one before dividing, and if that results in a value that is greater than the initial number, then try the original calculation. Spec added for ciel, but the issue doesn't appear to affect ciel, at least not for the same number. If the issue does effect ciel, a similar fix could probably work for it.

2021-05-29Fix Enumerator::ArithmeticSequence handling of float rangesJeremy Evans
Depending on the float range, there could be an off-by-one error, where the last result that should be in the range was missed. Fix this by checking if the computed value for the expected value outside the range is still inside the range, and if so, increment the step size.
