[PATCH 6.8 308/399] hexagon: vmlinux.lds.S: handle attributes section

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nathan Chancellor <nathan@xxxxxxxxxx>

commit 549aa9678a0b3981d4821bf244579d9937650562 upstream.

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.
