Subject: [PATCH] riscv: kexec: do not add '-mno-relax' flag if compiler doesn't support it
Date: Thu, 22 Jul 2021 10:17:15 +0800 [thread overview]
Message-ID: <20210722021715.127066-1-changbin.du@gmail.com> (raw)
The RISC-V special option '-mno-relax' which to disable linker relaxations
is supported by GCC8+. For GCC7 and lower versions do not support this
option.
