From 18931c892724cb9408811c793fe2656d11573b3a Mon Sep 17 00:00:00 2001 From: Andreas Schwab Date: Tue, 26 Feb 2013 16:55:54 +0000 Subject: arm64: fix padding computation in struct ucontext The expression to compute the padding needed to fill the uc_sigmask field to 1024 bits actually computes the padding needed for 1080 bits. Fortunately, due to the 16-byte alignment of the following field (uc_mcontext) the definition in glibc contains enough bytes of padding after uc_sigmask so that the overall offsets and size match in both definitions.
