Arm: Add read_description read funcs and use in GDB
Switch the Arm target to get target descriptions via arm_read_description and aarch32_read_description, in the same style as other feature targets. Add an enum to specify the different types - this will also be of use to gdbserver in a later patch. Under the hood return the same existing pre-feature target descriptions. gdb/ChangeLog: * Makefile.in: Add new files. * aarch32-tdep.c: New file. * aarch32-tdep.h: New file. * aarch64-linux-nat.c (aarch64_linux_nat_target::read_description): Call aarch32_read_description. * arch/aarch32.c: New file. * arch/aarch32.h: New file. * arch/arm.c (arm_create_target_description) (arm_create_mprofile_target_description): New function. * arch/arm.h (arm_fp_type, arm_m_profile_type): New enum.

Arm/AArch64: Use a single set of Arm register set size defines
Both targets were using a mixture of defines and hardcoded values. Add a standard set in arch/arm.h and use throughout, ensuring that none of the existing sizes change. No functionality changes. gdb/ChangeLog: * aarch32-linux-nat.h (VFP_REGS_SIZE): Remove define. * aarch64-linux-nat.c (fetch_fpregs_from_thread) (store_fpregs_to_thread) (aarch64_linux_nat_target::read_description): Use ARM_VFP3_REGS_SIZE. * arch/arm.h (IWMMXT_VEC_REGISTER_SIZE, ARM_CORE_REGS_SIZE) (ARM_FP_REGS_SIZE, ARM_VFP2_REGS_SIZE, ARM_VFP3_REGS_SIZE) (IWMMXT_REGS_SIZE): Add define. * arm-linux-nat.c (IWMMXT_REGS_SIZE): Remove define. (fetch_vfp_regs, store_vfp_regs) (arm_linux_nat_target::read_description): Use ARM_VFP3_REGS_SIZE. * arm-tdep.c (arm_register_g_packet_guesses): Use new defines. gdb/gdbserver/ChangeLog: * linux-aarch32-low.c (arm_read_description, arm_regsets): Use new defines. * linux-arm-low.c (arm_read_description, arm_regsets): Likewise. |

Arm: Prefix register sizes with ARM_

Normalize include guards in gdb
While working on my other scripts to deal with gdb headers, I noticed
that some files were missing include guards. I wrote a script to add
the missing ones, but found that using the obvious names for the
guards ran into clashes -- for example, gdb/nat/linux-nat.h used
"LINUX_NAT_H", but this was also the script's choice for
gdb/linux-nat.h.
So, I changed the script to normalize all include guards in gdb. This
patch is the result.
As usual the script is available here:
https://github.com/tromey/gdb-refactoring-scripts
Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the
buildbot.

Update copyright year range in all GDB files.
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files. |

Support software single step on ARM in GDBServer
This patch teaches GDBServer how to software single step on ARM
linux by sharing code with GDB.
The arm_get_next_pcs function in GDB is now shared with GDBServer. So
that GDBServer can use the function to return the possible addresses of
the next PC.
A proper shared context was also needed so that we could share the code,
this context is described in the arm_get_next_pcs structure.

Implement breakpoint_kind_from_pc and sw_breakpoint_from_kind for ARM in GDBServer.
ARM can have multiple breakpoint types based on the instruction set
it's currently in: arm, thumb or thumb2.
GDBServer needs to know what breakpoint is to be inserted at location
when inserting a breakpoint.
This is handled by the breakpoint_kind_from_pc and sw_breakpoint_from_kind
target ops introduced in a previous patch, this patch adds the
arm_breakpoint_kind_from_pc and arm_sw_breakpoint_from_kind implementation so
that the proper breakpoint type is returned based on the pc.
Also in order to share some code with GDB a new file called arm.c have been
introduced in arch/.
While this file does not contain much yet future patches will add more
to it thus the inclusion at this stage.
No regressions on Ubuntu 14.04 on ARMv7 and x86.

Move ARM register numbers enum to arch/arm.h
This patch moves ARM register numbers enum to arch/arm.h, so that it can used by GDBserver too. This patch also creates a new directory gdb/arch in which arch-specific or target-specific files are placed. gdb: 2015-07-30 Yao Qi <yao.qi@linaro.org> * arm-tdep.h (enum gdb_regnum): Move it to ... * arch/arm.h: ... here. New file. * Makefile.in (HFILES_NO_SRCDIR): Add arch/arm.h. |
