Rename common to gdbsupport This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

Support the fs_base and gs_base registers on i386. As on amd64, these registers hold the base address of the fs and gs segments, respectively. For i386 these two registers are 32 bits. gdb/ChangeLog: * amd64-fbsd-nat.c (amd64_fbsd_nat_target::read_description): Update calls to i386_target_description to add 'segments' parameter. * amd64-tdep.c (amd64_init_abi): Set tdep->fsbase_regnum.

(i386_gdbarch_init): Pass I386_NUM_REGS to set_gdbarch_num_regs. Add 'segments' parameter to call to i386_target_description. (i386_target_description): Add 'segments' parameter to enable segment base registers.
