hppa -z relro again
I misunderstood the hppa alias problem. File offsets of segments need
to be such that no page is mapped twice with different permissions.
(Which still seems to me like something the kernel could fix, but
anyhow, this is not so difficult to achieve in ld.)
PR 21000
bfd/
* elf-bfd.h (struct elf_backend_data): Add no_page_alias.
* elfxx-target.h (elf_backend_no_page_alias): Define.
(elfNN_bed): Init new field.
* elf.c (assign_file_positions_for_load_sections): If no_page_alias
ensure PT_LOAD segment starts on a new page.
* elf32-hppa.c (elf_backend_no_page_alias): Define.
ld/
* testsuite/ld-elf/loadaddr1.d: Adjust for hppa file offsets.
* testsuite/ld-elf/loadaddr2.d: Likewise.
* testsuite/ld-elf/loadaddr3a.d: Likewise.
* testsuite/ld-scripts/rgn-at5.d: Likewise.
