From 3da917d534954ae727a2174039a3786b474dd712 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Sat, 7 Mar 2020 08:24:35 -0800 Subject: [PATCH] ld: Add tests for -z nosectionheader and --strip-section-headers Add tests to verify that the linker option, -z nosectionheader and objcopy and strip option, --strip-section-headers, work correctly as well as linker issues an error when dynamic symbol table from PT_DYNAMIC segment is used.
