Complementing commit 280ca31f4d ("Add test for fetching TLS from
core file") extend gdb.threads/tls-core.exp with an OS-generated dump
where supported.
This verifies not only that our core dump interpreter is consistent
with our producer, but that it matches the OS verified as well,
avoiding a possible case where our interpreter would be bug-compatible
with our producer but not the OS and it would go unnoticed in testing.
This results in:
PASS: gdb.threads/tls-core.exp: native: load core file
PASS: gdb.threads/tls-core.exp: native: print thread-local storage variable
PASS: gdb.threads/tls-core.exp: gcore: load core file
PASS: gdb.threads/tls-core.exp: gcore: print thread-local storage variable
with local testing and:
UNSUPPORTED: gdb.threads/tls-core.exp: native: load core file
UNSUPPORTED: gdb.threads/tls-core.exp: native: print thread-local storage variable
PASS: gdb.threads/tls-core.exp: gcore: load core file
PASS: gdb.threads/tls-core.exp: gcore: print thread-local storage variable
with remote testing, or for testing on ports that don't supports
cores.
gdb/testsuite/ChangeLog:
2018-05-24 Maciej W. Rozycki <macro@mips.com>
Pedro Alves <palves@redhat.com>
* gdb.threads/tls-core.c: Include <stdlib.h>
(thread_proc): Call `abort'.
* gdb.threads/tls-core.exp: Generate a core with core_find too.
(tls_core_test): New procedure, bits factored out from ...
(top level): ... here. Test both native cores and gcore cores.
