*** TEST RESULTS FOR COMMIT f5424cfa7e9337a6cb02a1f83c9feea0995c5350 ***
Author: John Baldwin <jhb@FreeBSD.org>
Branch: master
Commit: f5424cfa7e9337a6cb02a1f83c9feea0995c5350
Support TLS variables on FreeBSD/amd64.
Use the fs_base register to fetch the address of a thread's tcb and
calculate the address of the DTV array. This value is then passed to
fbsd_get_thread_local_address to compute the final variable address.
Note that fs_base is currently only available via the native target as
core dumps on FreeBSD do not store the value of fs_base.
gdb/ChangeLog:
* amd64-fbsd-tdep.c (amd64fbsd_get_thread_local_address): New.
(amd64fbsd_init_abi): Install gdbarch
"fetch_tls_load_module_address" and "get_thread_local_address"
methods.
