| Subject: hexagon: vmlinux.lds.S: handle attributes section |
| Date: Tue, 19 Mar 2024 17:37:46 -0700 |
| |
| After the linked LLVM change, the build fails with |
| CONFIG_LD_ORPHAN_WARN_LEVEL="error", which happens with allmodconfig: |
| |
| ld.lld: error: vmlinux.a(init/main.o):(.hexagon.attributes) is being placed in '.hexagon.attributes' |
| |
| Handle the attributes section in a similar manner as arm and riscv by |
| adding it after the primary ELF_DETAILS grouping in vmlinux.lds.S, which |
| fixes the error. |
