From 5e24da908dbf6ddeb03e2b194f6b39dea3c660f3 Mon Sep 17 00:00:00 2001 From: Fangrui Song Date: Sun, 9 Jul 2023 10:57:19 -0700 Subject: PR30592 objcopy: allow --set-section-flags to add or remove SHF_X86_64_LARGE For example, objcopy --set-section-flags .data=alloc,large will add SHF_X86_64_LARGE to the .data section. Omitting "large" will drop the SHF_X86_64_LARGE flag. The bfd_section flag is named generically, SEC_ELF_LARGE, in case other processors want to follow SHF_X86_64_LARGE. SEC_ELF_LARGE has the same value as SEC_TIC54X_BLOCK used by coff. bfd/ * section.c: Define SEC_ELF_LARGE. * bfd-in2.h: Regenerate. * elf64-x86-64.c (elf_x86_64_section_flags, elf_x86_64_fake_sections, elf_x86_64_copy_private_section_data): New. binutils/ * NEWS: Mention the new feature for objcopy. * doc/binutils.texi: Mention "large". * objcopy.c (parse_flags): Parse "large".
