2019-06-06[BFD, AArch64] Fix PT_GNU_PROPERTY alignment issueSudakshina Das2-0/+13
If the new GNU property section was being created by the linker (this will happen only if none of the inputs have any GNU property section but the command line to the linker forces a bti with --force-bti), the alignment of the section and hence the program header of PT_GNU_PROPERTY type was not being set correctly. This patch fixes this issue. bfd/ChangeLog: 2019-06-06 Sudakshina Das <sudi.das@arm.com> * elfxx-aarch64.c (_bfd_aarch64_elf_link_setup_gnu_properties): Set alignment of the new gnu property section. ld/ChangeLog: 2019-06-06 Sudakshina Das <sudi.das@arm.com> * testsuite/ld-aarch64/aarch64-elf.exp: Add new tests. * testsuite/ld-aarch64/property-bti-pac4-a.d: New test. * testsuite/ld-aarch64/property-bti-pac4-b.d: New test. * testsuite/ld-aarch64/property-bti-pac4.s: New test.

2019-05-28Obsolete tic30-aout, and linker segmentation faultsAlan Modra3-32/+75
See also the FIXME. tic30-aout linker support is so bad (and has been that way since the initial tic30-aout commit) that I'm obsoleting the target. This patch fixes numerous linker testsuite segmentation faults.

2019-05-28XCOFF linker segmentation faultAlan Modra3-8/+20
The XCOFF linker temporarily trims the output bfd section list, without adjusting section_count to suit. This is a little rude, but the dwarf line number code can easily cope with this situation. So check for a NULL end of list as well as limiting the saved section VMAs to the first section_count list entries. Also fixes -FAIL: Weak test 3 (main, static) (32-bit) -FAIL: Weak test 3 (main, static) (64-bit) PR 24596 * dwarf2.c (save_section_vma, section_vma_same): Check for NULL end of section list as well as section_count. * xcofflink.c (xcoff_link_add_symbols): Fix temporarily changed section list before returning error.
