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

[Meera Nakrani via Phabricator via llvm-commits]

MeeraN updated this revision to Diff 293170.
MeeraN retitled this revision from "[ARM][TTI] Prevents constants in a min/max pattern from being hoisted when in a loop" to "[ARM][TTI] Prevents constants in a min(max) or max(min) pattern from being hoisted when in a loop".
MeeraN added a comment.

Added new helper function isSSATMinMaxPattern which checks whether the instruction being passed in is a valid max instruction that is part of a min(max()) or max(min()) pattern. Simplified getIntImmCostInst down to make a call to this function.
