From 3fb3ffccea717ce10bb29dfd8a9e761c7387626e Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Sun, 14 Jul 2019 14:05:48 +0100 Subject: [build] Fix use of inline assembly on GCC 8 ARM64 builds Commit 1a7746603 ("[build] Fix use of inline assembly on GCC 4.8 ARM64 builds") switched from using "%c0" to "%a0" in order to avoid an "invalid operand prefix" error on the ARM64 version of GCC 4.8. It appears that the ARM64 version of GCC 8 now produces an "invalid address mode" error for the "%a0" form, but is happy with the original "%c0" form. Switch back to using the "%c0" form, on the assumption that the requirement for "%a0" was a temporary aberration. Originally-fixed-by: John L.
