Bug ID: 41162
Summary: Implement LKK remainder and divisibility algorithms
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Scalar Optimizations
Assignee: unassignedb...@nondot.org
Reporter: sfi...@hotmail.com
CC: llvm-bugs@lists.llvm.org
New algorithms can improve the performance of remainder and divisibility. See
"Faster remainders when the divisor is a constant: beating compilers and
libdivide" at
https://lemire.me/blog/2019/02/08/faster-remainders-when-the-divisor-is-a-constant-beating-compilers-and-libdivide/
and the paper "Faster Remainder by Direct Computation: Applications to
Compilers and Software Libraries" by Daniel Lemire, Owen Kaser, and Nathan Kurz
at https://arxiv.org/pdf/1902.01961.pdf .
(This has the potential to improve C++17 charconv performance.)
