From a864243fb7ae1932341fce17598cfc588150156d Mon Sep 17 00:00:00 2001 From: Dimitry Andric Date: Sat, 25 Nov 2023 20:15:54 +0100 Subject: [PATCH] sysutils/opensbi: fix build with clang 17 Building sysutils/opensbi with clang 17 results in the following errors: clang: error: unsupported option '-mno-unaligned-access' for target 'riscv64-unknown-elf' clang: error: unsupported option '-mno-unaligned-access' for target 'riscv64-unknown-elf' [... many more times...] The target-specific option -mno-unaligned-access (which is emitted from the compiler driver when -mstrict-align is used) did not do anything for riscv64, but clang 17 is now more strict about reporting unsupported options. Remove the -mstrict-align option from the Makefile's CFLAGS and ASFLAGS to fix it.
