Subject: [PATCH] core: link: add --no-warn-rwx-segments
Signed-off-by: Anton Antonov <Anton.Antonov@arm.com>
Upstream-Status: Backport [https://github.com/OP-TEE/optee_os/pull/5474]
binutils ld.bfd generates one RWX LOAD segment by merging several sections
with mixed R/W/X attributes (.text, .rodata, .data). After version 2.38 it
also warns by default when that happens [1], which breaks the build due to
--fatal-warnings. The RWX segment is not a problem for the TEE core, since
that information is not used to set memory permissions. Therefore, silence
the warning.
