Subject: [PATCH v5 0/4] Enable orphan-handling=warn for VDSO
Date: Tue, 10 May 2022 10:58:30 +0100 [thread overview]
Message-ID: <20220510095834.32394-1-joey.gouly@arm.com> (raw)
Hi all,
This small series enables the orphan-handling linker flag for the VDSO.
This could catch subtle errors if features that use special sections are
introduced into the VDSO implementation.
Tested by running the VDSO self tests.
Tested building with LLVM LLD and Binutils LD linkers.
Changes from v4 [1]:
- Add more sections that showed up when using binutils ld
Thanks,
Joey
