From fde51dd189a1f8a63896bcb845ef36ea5e1917d5 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Tue, 4 Dec 2018 06:00:57 -0800 Subject: x86: Don't remove empty GNU_PROPERTY_X86_UINT32_OR_AND properties For GNU_PROPERTY_X86_COMPAT_ISA_1_USED and GNU_PROPERTY_X86_UINT32_OR_AND properties, a bit in the output pr_data field is set if it is set in any relocatable input pr_data fields and this property is present in all relocatable input files. A missing property implies that its bits have unknown values. When all bits in the the output pr_data field are zero, this property should not be removed from output to indicate it has zero in all bits. bfd/ PR ld/23372 * elfxx-x86.c (_bfd_x86_elf_merge_gnu_properties): Don't remove empty properties for GNU_PROPERTY_X86_COMPAT_ISA_1_USED and GNU_PROPERTY_X86_UINT32_OR_AND.
