dmgreen added inline comments.
================
Comment at: llvm/lib/Target/AArch64/AArch64Subtarget.cpp:82
case CortexA35:
+ MaxBytesForLoopAlignment = 8;
break;
----------------
This needn't be set if there is no PrefLoopLogAlignment set too.
Either that, or it can be treated like a CortexA53/A55 below by adding it to the same case block.
================
Comment at: llvm/test/CodeGen/AArch64/aarch64-p2align-max-bytes-neoverse.ll:9
+; RUN: llc -mtriple=aarch64-none-linux-gnu -mcpu=cortex-a75 < %s -o -| FileCheck %s --check-prefixes=CHECK,CHECK-8
+; RUN: llc -mtriple=aarch64-none-linux-gnu -mcpu=cortex-a510 < %s -o -| FileCheck %s --check-prefixes=CHECK,CHECK-8
----------------
Should this be checking for 4, 8? Can we add some of the other cpus like A53 and A55 too?
