From 780ef4857aba77fa771eb6a4ae4e7359645c9484 Mon Sep 17 00:00:00 2001 From: Jessica Clarke Date: Sat, 20 Mar 2021 20:43:05 +0000 Subject: Support building on macOS/arm64 On Arm-based Macs, -no_pie is ignored and gives a linker warning. Moreover, the build falls over with: ld: Absolute addressing not allowed in arm64 code but used in '_image_type_ptr_aisimage' referencing '_image_type_aisimage' for dumpimage and mkimage, since we put data structs in text sections not data sections and so cannot have dynamic relocations. Instead, move the sections to __DATA and drop disabling PIE.
