From 98e55f97afc2a212185804e2c1130bebe980db73 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marek=20Beh=C3=BAn?= Date: Thu, 20 May 2021 13:24:00 +0200 Subject: [PATCH] lib: crc32: put the crc_table variable into efi_runtime_rodata section MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When compiling with LTO, the compiler fails with an error saying that `crc_table` causes a section type conflict with `efi_var_buf`. This is because both are declared to be in the same section (via macro `__efi_runtime_data`), but one is const while the other is not. Put this variable into the section .rodata.efi_runtime, instead of .data.efi_runtime, via macro __efi_runtime_rodata.
