From c776deed60b3d7f30f3095ee98c3f0b3c815c348 Mon Sep 17 00:00:00 2001 From: Dimitris Papastamos Date: Fri, 13 Oct 2017 15:07:45 +0100 Subject: Change Statistical Profiling Extensions build option handling It is not possible to detect at compile-time whether support for an optional extension such as SPE should be enabled based on the ARM_ARCH_MINOR build option value. Therefore SPE is now enabled by default.
