[PATCH] D87457: [ARM][TTI] Prevents constants in a min/max pattern from being hoisted when in a loop

[Meera Nakrani via Phabricator via llvm-commits]

MeeraN updated this revision to Diff 293120.
MeeraN added a comment.

Improved getIntImmCostInst so that the max(min()) case is properly handled by checking the instruction's operand is a min and a select instruction.
