* symfile.c (addr_section_name): New function.
(addrs_section_compar): Use it.
(addr_info_make_relative): Use it. Move variable sect_name into a more
inner block. Make ".dynbss" and ".sdynbss" checks more strict.
gdb/testsuite/
* gdb.base/prelink-lib.c (copyreloc): New initialized variable.
* gdb.base/prelink.c (copyreloc, bssvar, bssvarp): New variables.
(main): Use copyreloc.
* gdb.base/prelink.exp (split debug of executable)
(.dynbss vs. .bss address shift): New tests.
* gdb.base/attach-pie-misread.exp: Load prelink-support.exp. Replace
build_executable by build_executable_own_libs. Replace "prelink -R"
execution by a call of prelink_yes. Comment why "prelink -r" needs no
change.
* gdb.base/break-interp.exp: Load prelink-support.exp. Rename calls of
copy to file_copy. Move setting opts --dynamic-linker and -rpath,
mkdir $dir and ldd its parsing and copying to lib/prelink-support.exp.
Replace build_executable by build_executable_own_libs's function
build_executable_own_libs.
(prelinkNO): Create new stub to call prelink_no.
(prelinkYES): Create new stub to call prelink_yes.
(test_attach): Rename calls of copy to file_copy.
(section_get, prelinkNO_run, prelinkNO, prelinkYES, symlink_resolve)
(copy): Move to ...
* lib/prelink-support.exp: ... a new file. Rename prelinkNO to
prelink_no, prelinkYES to prelink_yes, copy to file_copy.
* gdb.base/prelink.exp: Disable testcase also for is_remote and
skip_shlib_tests. Load prelink-support.exp. Replace gdb_compile with
special flags by gdb_compile_shlib. Replace second gdb_compile by
build_executable_own_libs. Replace "prelink -R" execution by a call of
prelink_yes. Replace "prelink -u" and second "prelink -R" execution by
a second call of prelink_yes. Replace restart commands by
clean_restart.
(prelink): Rename to ...
(seen displacement message): ... this test. Extend its expectation
strictness.
* solib-svr4.c (LM_ADDR_CHECK) <info_verbose>: Use printf_unfiltered
for the PIC displacement, print also the displacement value.
(svr4_exec_displacement): Print DISPLACEMENT if INFO_VERBOSE.
gdb/testsuite/
* gdb.base/break-interp.exp: Create new displacement parameter value
for the test_ld calls.
(reach): New parameter displacement, verify its content. New push of
pf_prefix "reach-$func:". Import global expect_out.
(test_core): New parameter displacement, verify its content. New push
of pf_prefix "core:". New command "set verbose on". Import global
expect_out.
(test_attach): New parameter displacement, verify its content. New
push of pf_prefix "attach:". New command "set verbose on". Import
global expect_out.
(test_ld): New parameter displacement, pass it to the reach, test_core
and test_attach calls and verify its content in the "ld.so exit" test.
* gdb.base/prelink.exp: Remove gdb_exit and final return.
(prelink): Update expected text, use gdb_test.
* solib-svr4.c (svr4_current_sos): Move up initialization of
l_addr, such that it clearly covers all cases.
gdb/testsuite/ChangeLog:
* gdb.base/prelink.exp: Anchor tested-for regular expression
on gdb prompt.
* gdb.base/prelink.exp: Likewise. Add -q to prelink runs.
Rename executable to prelinkt. Don't re-prelink if we didn't
get a core file. Test prelink -u exit status to tell whether
prelinking failed. Use gdb_test_multiple.
