Divisions by a constant can be converted into multiplies which are usually cheaper, but this isn't possible if the constant gets separated (particularly in loops). Fix this by telling ConstantHoisting that the immediate in a DIV is cheap. I considered making the check generic, but neither AArch64 (strangely) nor x86 showed any benefit on the tests I had. llvm-svn: 266464 |
