From 7e1d0925526a104364630b7af5355b799ef884d9 Mon Sep 17 00:00:00 2001 From: Robert Marko Date: Mon, 16 Sep 2024 11:51:45 +0200 Subject: [PATCH] generic: enable RELR relocations RELR is a relocation packing format for relative relocations. Linux has supported using it for ARM64 since 5.4, and more recently for LoongArch as well. It requires compatible tooling as well, so only with binutils 2.43 TOOLS_SUPPORT_RELR is set and thus RELR available. RELR should always decrease the binary size and while testing this the default build for Dynalink WRX-36 (qualcommax/ipq807x) reduced the compressed kernel size by 38k and uncompressed one by 640k. So, lets enable it in the default config.
