From 0a59ff65df6da8267efb5c97dead8cd0dcd5b445 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Pekka=20Sepp=C3=A4nen?= Date: Wed, 20 Sep 2023 19:41:01 +0100 Subject: [PATCH] aarch64: Ensure const and sign correctness MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Be const and sign correct by using a matching CIE augmentation type. Use a builtin instead of relying being included. libgcc/ChangeLog: * config/aarch64/aarch64-unwind.h (aarch64_cie_signed_with_b_key): Use const unsigned type and a builtin.
