gdb: Have allocate_target_description return a unique_ptr
There were a few places where we could (should?) have delayed
releasing the target_desc_up until a little later. This commit
catches these cases.
In the case of ARC, the target_desc_up is now exposed right out to
gdbserver, which means making a small change there too.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* arch/aarch32.c (aarch32_create_target_description): Release the
target_desc_up as late as possible.
* arch/aarch64.c (aarch64_create_target_description): Likewise.
* arch/amd64.c (amd64_create_target_description): Likewise.
* arch/arc.c (arc_create_target_description): Return a
target_desc_up, don't release it.
* arch/arc.h (arc_create_target_description): Update declaration.
(arc_lookup_target_description): Move target_desc_up into the
cache, and return a borrowed pointer.
* arch/arm.c (arm_create_target_description): Release the
target_desc_up as late as possible.
* arch/i386.c (i386_create_target_description): Likewise.
* arch/riscv.h (riscv_create_target_description): Update
declaration to match definition.
* arch/tic6x.c (tic6x_create_target_description): Release the
target_desc_up as late as possible.
gdbserver/ChangeLog:
* linux-arc-low.cc (arc_linux_read_description): Release the
unique_ptr returned from arc_create_target_description.
In arm arm_create_target_description and
aarch32_create_target_description create feature based target descriptions
instead of returning the old style descriptions.
Ensure the descriptions are created in exactly the same way as the old xml
files.
Remove the old initialize calls.
gdb/ChangeLog:
* arch/aarch32.c (aarch32_create_target_description): Create
target descriptions using features.
* arch/arm.c (arm_create_target_description)
(arm_create_mprofile_target_description): Likewise.
* arm-tdep.c (_initialize_arm_tdep): Remove tdesc init calls.
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_create_target_description)
(arm_create_mprofile_target_description): New declaration.
* arm-fbsd-tdep.c (arm_fbsd_read_description_auxv): Call
read_description functions.

Likewise.

function.
