From aa0cbc1b506b090c3a775b547c693ada108cc0d7 Mon Sep 17 00:00:00 2001 From: WANG Rui Date: Tue, 21 Nov 2023 15:03:25 +0800 Subject: LoongArch: Record pc instead of offset in la_abs relocation To clarify, the previous version functioned flawlessly. However, it's worth noting that the LLVM's LoongArch backend currently lacks support for cross-section label calculations. With this patch, we enable the use of clang to compile relocatable kernels.
