Yao Qi 1c90d9f022 Class-fy dwarf2_frame_state_reg_info
This patch adds dwarf2_frame_state_reg_info ctor, dtor, copy ctor,
assignment operator, and move assignment.  This patch also adds unit test
to execute_cfa_program to cover the changes.

Yao Qi afe37d6be5 Class-fy dwarf2_frame_state
This patch adds ctor and dtor to dwarf2_frame_state, so that we can
remove one cleanup "old_chain".

Yao Qi b348037fd8 Move dwarf2_frame_state_reg.exp_len to union .loc
dwarf2_frame_state_reg.exp_len is only used together with .loc.exp, so
it makes more sense to exp_len to the union as well.

gdb:

Jiong Wang b41c5a85a7 [gdbarch] New method "execute_dwarf_cfa_vendor_op" and migrate SPARC to it
Recently a feature called "return address signing" has been added to GCC to
prevent stack smash stack on AArch64.  For details please refer:

  https://gcc.gnu.org/ml/gcc-patches/2017-01/msg00376.html

GDB needs to be aware of this feature so it can restore the original return
address which is critical for unwinding.

On compiler side, whenever return address, i.e. LR register, is mangled or
restored by hardware instruction, compiler is expected to generate a
DW_CFA_AARCH64_negate_ra_state to toggle return address signing status.

DW_CFA_AARCH64_negate_ra_state is using the same CFI number and
therefore need to be multiplexed with DW_CFA_GNU_window_save which was designed
for SPARC.

A new gdbarch method "execute_dwarf_cfa_vendor_op" is introduced by this patch.
It's parameters has been restricted to those only needed by SPARC and AArch64
for multiplexing DW_CFA_GNU_window_save which is a CFI operation takes none
operand.  Should any further DWARF CFI operation want to be multiplexed in the
future,  the parameter list can be extended.  Below is the current function
prototype.

   typedef int (gdbarch_execute_dwarf_cfa_vendor_op_ftype)
     (struct gdbarch *gdbarch, gdb_byte op, struct dwarf2_frame_state *fs);

DW_CFA_GNU_window_save support for SPARC is migrated to this new gdbarch
method by this patch.

gdb/
	* gdbarch.sh: New gdbarch method execute_dwarf_cfa_vendor_op.
	* gdbarch.c: Regenerated.
	* gdbarch.h: Regenerated.
	* dwarf2-frame.c (dwarf2_frame_state_alloc_regs): Made the
	visibility external.
	(execute_cfa_program): Call execute_dwarf_cfa_vendor_op for CFI
	between DW_CFA_lo_user and DW_CFA_high_user inclusive.
	(enum cfa_how_kind): Move to ...
	(struct dwarf2_frame_state_reg_info): Likewise.
	(struct dwarf2_frame_state): Likewise.
	* dwarf2-frame.h: ... here.
	(dwarf2_frame_state_alloc_regs): New declaration.
	* sparc-tdep.c (sparc_execute_dwarf_cfa_vendor_op): New function.
	(sparc32_gdbarch_init): Register execute_dwarf_cfa_vendor_op hook.

Tom Tromey a8fd558970 split dwarf2_fetch_cfa_info from dwarf2_compile_expr_to_ax
This removes dwarf2_compile_expr_to_ax, replacing it with a utility
function that fetches the CFA data and adding the code to actually
compile to an agent expression directly into
dwarf2_compile_expr_to_ax.  This refactoring lets a later patch reuse
the new dwarf2_fetch_cfa_info.

Joel Brobecker 28e7fd6234 Update years in copyright notice for the GDB files.
Two modifications:
  1. The addition of 2013 to the copyright year range for every file;
  2. The use of a single year range, instead of potentially multiple
     year ranges, as approved by the FSF.
