From 5a534314a85b735f766aa64b35697ed1d59f7068 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 24 Oct 2023 17:35:05 +0100 Subject: [PATCH] target/arm: Move feature test functions to their own header MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The feature test functions isar_feature_*() now take up nearly a thousand lines in target/arm/cpu.h. This header file is included by a lot of source files, most of which don't need these functions. Move the feature test functions to their own header file.
