From mboxrd@z Thu Jan 1 00:00:00 1970 From: Thomas Petazzoni Date: Sun, 3 May 2020 23:26:39 +0200 Subject: [Buildroot] [PATCH] package/libunwind: enable on AArch64 Message-ID: <20200503212640.189571-1-thomas.petazzoni@bootlin.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Since version 1.2, libunwind has support for the AArch64 architecture. It builds fine on glibc, needs a small patch on musl, but doesn't build with uClibc (stack_t undefined).
