Subject: [PATCH v1 06/14] DCE/DSE: add HAVE_SECTION_SHF_GROUP_SUPPORT option
Date:   Sat,  4 Nov 2023 00:00:14 +0800
Message-Id: <04271c1f3a4c3d369310146faefc0d05144276e9.1699025537.git.tanyuan@tinylab.org>

Precedence: bulk

SHF_GROUP requires ld >= 2.36.

LLD supports SHF_GROUP too, but it does not support riscv
HAVE_LD_DEAD_CODE_DATA_ELIMINATION. Therefore, I haven't tested the
minimum compatible version yet.
