Subject: [PATCH] powerpc/boot: move the .got section to after the .dynamic section
Date: Fri, 16 Oct 2020 17:01:51 -0700 [thread overview]
Message-ID: <20201017000151.150788-1-morbo@google.com> (raw)
Both .dynamic and .got are RELRO sections and should be placed together,
and LLD emits an error:
ld.lld: error: section: .got is not contiguous with other relro sections
Place them together to avoid this.
