PR22758, FAIL: Run pr22393-2
We can't map different disk pages into the same memory page; The last
page mapped will simply overwrite any previous pages. The
executable/non-executable new_segment test ignored this fact, leading
to a ld.so segfault on hppa when .dynamic is overwritten with zeros.
This patch moves existing tests for demand paging with lma on the same
memory page, to a new test performed before any case where we want a
new segment due to protection or loadable conflicts.
PR 22758
* elf.c (_bfd_elf_map_sections_to_segments): Don't start a new
segment when demand paged with lma on the same page. Test this
before load/non-load, executable/non-executable,
writable/non-writable tests and simplify. Delete bogus relro
condition in writable/non-writable test. Delete outdated
comment. Formatting.
