Subject: [PATCH] MIPS: generic: Support linking with LLVM ld.lld
Date: Sun, 21 Mar 2021 13:18:05 +0000 [thread overview]
Message-ID: <20210321131805.98422-1-paul@crapouillou.net> (raw)
LLVM's ld.lld chokes on the 64-bit sign-extended load addresses. Use
32-bit addresses if the linker is LLVM's ld.lld.
Signed-off-by: Paul Cercueil <paul@crapouillou.net>
