From ca7e10bff196f69a450b9072a7b757713d3bb2dd Mon Sep 17 00:00:00 2001 From: Sami Tolvanen Date: Thu, 8 Sep 2022 14:55:01 -0700 Subject: x86/tools/relocs: Ignore __kcfi_typeid_ relocations The compiler generates __kcfi_typeid_ symbols for annotating assembly functions with type information. These are constants that can be referenced in assembly code and are resolved by the linker. Ignore them in relocs.
