With the new data structures it is trivial to add a new field and we
aren't (too) limited as to the number we have. This patch adds a new
bit to describe the need for a particular compiler behaviour
modification: in this case a quirk in the cortex-m3.
* arm-isa.h (enum isa_feature): Add isa_quirk_cm3_ldrd.
(ISA_ALL_QUIRKS): New macro.
* arm-cores.def (cortex-m3): Add isa_quirk_cm3_ldrd to isa feature list.
* arm.c (isa_quirkbits): New feature-list bitmap.
(arm_configure_build_target): Ignore quirk bits when comparing an
architecture feature list with a CPU feature list.
(arm_option_override): Initialize_isa_quirkbits. If the user has
not specified -m[no-]fix-cortex-m3-ldrd, automatically enable the
feature if isa_quirk_cm3_ldrd appears in the isa feature list.

Make more use of the new data structure for initializing existing
variables.
* arm.c (arm_option_override): Use arm_active_target as source of
information for arm_base_arch and arm_arch_name.
* (arm_file_start): Use arm_active_target for core name.
From-SVN: r243700
We now start to make more use of the new data structure. This allows
us to eliminate two of the existing static variables,
arm_selected_arch and arm_selected tune.
* arm.c (arm_selected_tune): Delete static variable.
(arm_selected_arch): Likewise.
(arm_configure_build_target): Declare local versions of arm_selected
target and arm_selected_arch. Initialize more fields in target
data structure.
(arm_option_override): Use arm_active_target instead of
arm_selected_tune and arm_selected_arch.
(asm_file_start): Use arm_active_target.

This patch creates a new data structure for carrying around the data
relating to the current compilation target. The idea behind this is
that this data structure can be updated to reflect the overall
compilation target as new information is gathered (from command line
options) or architectural extensions. We will no-longer have to grub
around looking in multiple places for this information.
There are some small behaviour changes around how we handle selecting
a default CPU if thumb or interworking are specified on the command
line and the default CPU does not support thumb, but I believe the
existing code was broken in that respect. This code will go away once
we obsolete pre-armv4t devices.
* arm-protos.h (arm_build_target): New structure.
(arm_active_target): Declare it.
* arm.c (arm_active_target): New variable.
(bitmap_popcount): New function.
(feature_count): Delete.
(arm_initialize_isa): New function.
isa_fpubits): New variable.
(arm_configure_build_target): New function.
(arm_option_override): Initialize isa_fpubits and arm_active_target.isa.
Use arm_configure_build_target.

This patch adds the new ISA data structures. The idea is to use an
sbitmap for carrying these around internally. We don't make much use
of this yet, but will increasingly migrate over to this in the
following patches. All cores and architectures currently have both
old and new encodings for now.
For simplicity and clarity we introduce internally the concept of
ARMv7ve. It doesn't change any visible behaviour.
There's also a bit of tidying up of the various supported cores,
sorting them by profile.
* arm-isa.h: New file.
* arm-protos.h: Include it.
* arm-arches.def: Add new ISA field to all entries. Drop bogus
armv8.1-a+crc architecture.
* arm-cores.def: Similarly. Group ARMv8 cores by profile.
* arm-opts.h (enum processor_type): Adjust for new field.
* arm.c (struct processors): New field 'isa_bits'.
(all_cores, all_architectures): Initialize new field.
* arm-tables.opt: Regenerated.
* arm-tune.md: Regenerated.
From-SVN: r243697
We start out by separating the 'tuning flags' in a CPU or architecture
specification into a new field in the data structures. Because there
aren't very many of these (and we'd like to get rid of them entirely,
eventually, moving to entries in the tuning tables), we just use a
simple unsigned word. This frees up a number of bits in the main
flags data structure, but we don't consolidate them as we'll be
getting rid of them entirely shortly.
There's one small user-visible change, the slow multiply flag is moved
from being treated as an architectural flag to a tuning flag. This
has two consequences: it's now ignored for architectural matching to a
CPU and specifying a -mtune option will now correctly apply the
multiply performance to the decision as to which sequences to
synthesise.
* arm-arches.def (ARM_ARCH): Add extra field TUNE_FLAGS, move
tuning properties from architectural FLAGS field.
* arm-cores.def (ARM_CORE): Likewise.
* arm-protos.h (TF_LDSCHED, TF_WBUF, TF_CO_PROC): New macros.
(TF_SMALLMUL, TF_STRONG, TF_SCALE, TF_NOMODE32): New macros.
(FL_LDSCHED, FL_STRONG, FL_WBUF, FL_SMALLMUL): Delete.
(FL_TUNE): Remove deleted elements.
(tune_flags): Convert type to unsigned int.
* arm.c (struct processors): Add new field tune_flags.
(all_cores, all_arches): Initialize it.
(arm_option_override): Adapt uses of tune_flags. Use tune_flags
for deciding when we should have slow multiply operations.
