* 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.
