From cde6497d286337de2ed21c71c85157e2745b742b Mon Sep 17 00:00:00 2001 From: Vladimir Marko Date: Tue, 25 Apr 2023 16:40:06 +0000 Subject: Optimizing: Add `HInstruction::As##type()`. After the old implementation was renamed in https://android-review.googlesource.com/2526708 , we introduce a new function with the old name but new behavior, just `DCHECK()`-ing the instruction kind before casting down the pointer. We change appropriate calls from `As##type##OrNull()` to `As##type()` to avoid unncessary run-time checks and reduce the size of libart-compiler.so.
