File _service:tar_scm:LoongArch-Prepare-static-PIE-support.patch of Package gcc
From aa2d9e0e1dc4bf0b612618cf0e3fcea514f92f95 Mon Sep 17 00:00:00 2001 From: Xi Ruoyao <xry111@xry111.site> Date: Tue, 13 Sep 2022 23:21:39 +0800 Subject: [PATCH 018/124] LoongArch: Prepare static PIE support Static PIE allows us to extend the ASLR to cover static executables and it's not too difficult to support it. On GCC side, we just pass a group of options to the linker, like other ports with static PIE support. The real implementation of static PIE (rcrt1.o) will be added into Glibc later. gcc/ChangeLog: * config/loongarch/gnu-user.h (GNU_USER_TARGET_LINK_SPEC): For -static-pie, pass -static -pie --no-dynamic-linker -z text to the linker, and do not pass --dynamic-linker.
