Subject: [PATCH] efi_loader: Fix link of EFI apps with ld.lld
Date: Wed, 20 Oct 2021 21:31:31 +0000 [thread overview]
Message-ID: <20211020213134.7534-3-adelva@google.com> (raw)
In-Reply-To: <20211020213134.7534-1-adelva@google.com>
When compiling U-Boot with ld.lld as the linker, the helloworld EFI app
example fails to link:
LD lib/efi_loader/helloworld_efi.so
ld.lld: error: section: .dynamic is not contiguous with other relro
sections
LLD will always create RELRO program header regardless of target
emulation, whereas BFD may automatically disable it for unsupported
targets. Add -znorelro to disable it explicitly in all cases.
