From: Nelson Chu Date: Fri, 9 Jul 2021 03:22:20 +0000 (-0700) Subject: RISC-V: Enable elf attributes when default configure option isn't set. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=aa0587b290e9155e71c01447c0e3f57c3ee0ecc3;p=binutils-gdb.git RISC-V: Enable elf attributes when default configure option isn't set. Since gcc commit, 3c70b3ca1ef58f302bf8c16d9e7c7bb8626408bf, we now enable elf attributes for all riscv targets by default in gcc. Therefore, I think binutils should have the same behavior, in case users are writing assembly files. If --enable-default-riscv-attribute isn't set, then we enable the elf attributes for all riscv targets by default.
