elf: Allow mixed ordered/unordered inputs for non-relocatable link
For non-relocatable link with SHF_LINK_ORDER inputs, allow mixed indirect and data inputs with ordered and unordered inputs: 1. Add pattern to bfd_section for the matching section name pattern in linker script and update BFD_FAKE_SECTION. 2. Sort the consecutive bfd_indirect_link_order sections with the same pattern to allow linker script to overdide input section order. 3. Place unordered sections before ordered sections. 4. Change the offsets of the indirect input sections only. bfd/ PR ld/26256 * elflink.c (compare_link_order): Place unordered sections before ordered sections. (elf_fixup_link_order): Add a link info argument. Allow mixed ordered and unordered input sections for non-relocatable link. Sort the consecutive bfd_indirect_link_order sections with the same pattern. Change the offsets of the bfd_indirect_link_order sections only. (bfd_elf_final_link): Pass info to elf_fixup_link_order. * section.c (bfd_section): Add pattern. (BFD_FAKE_SECTION): Initialize pattern to NULL. * bfd-in2.h: Regenerated. gas/ PR ld/26256 * config/obj-elf.c (obj_elf_change_section): Also filter out SHF_LINK_ORDER. ld/ PR ld/26256 * ldlang.c (gc_section_callback): Set pattern. * testsuite/ld-elf/pr26256-1.s: New file. * testsuite/ld-elf/pr26256-1.t: Likewise. * testsuite/ld-elf/pr26256-1a.d: Likewise. * testsuite/ld-elf/pr26256-1b.d: Likewise. * testsuite/ld-elf/pr26256-2.s: Likewise. * testsuite/ld-elf/pr26256-2.t: Likewise. * testsuite/ld-elf/pr26256-2a.d: Likewise. * testsuite/ld-elf/pr26256-2b-alt.d: Likewise. * testsuite/ld-elf/pr26256-2b.d: Likewise. * testsuite/ld-elf/pr26256-3.s: Likewise. * testsuite/ld-elf/pr26256-3a.d: Likewise. * testsuite/ld-elf/pr26256-3a.t: Likewise. * testsuite/ld-elf/pr26256-3b.d: Likewise. * testsuite/ld-elf/pr26256-3b.t: Likewise.
