This patch fixes gcc warning when build ARM GDBserver and AArch64
GDBserver,
AArch64 GDBserver:
gdb/gdbserver/linux-aarch32-low.h:36:29: error: 'thumb2_breakpoint' defined but not used [-Werror=unused-const-variable]
static const unsigned short thumb2_breakpoint[] = { 0xf7f0, 0xa000 };
^
gdb/gdbserver/linux-aarch32-low.h:34:29: error: 'thumb_breakpoint' defined but not used [-Werror=unused-const-variable]
static const unsigned short thumb_breakpoint = 0xde01;
^
gdb/gdbserver/linux-aarch32-low.h:28:28: error: 'arm_breakpoint' defined but not used [-Werror=unused-const-variable]
static const unsigned long arm_breakpoint = arm_eabi_breakpoint;
^
cc1: all warnings being treated as errors
ARM GDBserver:
gdb/gdbserver/linux-aarch32-low.h:34:29: error: 'thumb_breakpoint' defined but not used [-Werror=unused-const-variable]
static const unsigned short thumb_breakpoint = 0xde01;
^~~~~~~~~~~~~~~~
gdb/gdbserver/linux-aarch32-low.h:28:28: error: 'arm_breakpoint' defined but not used [-Werror=unused-const-variable]
static const unsigned long arm_breakpoint = arm_eabi_breakpoint;
^~~~~~~~~~~~~~
by simply moving these macros and variables to
linux-aarch32-low.c and only declare thumb2_breakpoint in
linux-aarch32-low.h, which is not perfect, and reveals some issues
in recent arm GDBserver software single step changes. I'll post
follow-up patches.
gdb/gdbserver:
2016-01-06 Yao Qi <yao.qi@linaro.org>
* linux-aarch32-low.h (arm_abi_breakpoint): Move to
linux-aarch32-low.c.
(arm_eabi_breakpoint, arm_breakpoint): Likewise.
(arm_breakpoint_len, thumb_breakpoint_len): Likewise.
(thumb2_breakpoint, thumb2_breakpoint_len): Likewise.
(thumb2_breakpoint): Declare.
* linux-aarch32-low.c (arm_abi_breakpoint): Moved from
linux-aarch32-low.h.
(arm_eabi_breakpoint, arm_breakpoint): Likewise.
(arm_breakpoint_len, thumb_breakpoint_len): Likewise.
(thumb2_breakpoint, thumb2_breakpoint_len): Likewise.
