Rather than assuming a specific fpu name has been selected, we work
out the FPU from the ISA properties.  This is necessary since once we
have default FPUs selected by the processor, there will be no explicit
entry in the table of fpus to refer to.

This also fixes a bug with the code I added recently to permit new
aliases for existing FPU names: the new names cannot be passed to the
assembler since it does not recognize them.  By mapping the ISA
features back to the canonical names we avoid having to teach the
assembler about the new names.

	* arm.h (TARGET_FPU_NAME): Delete.
	* arm.c (arm_identify_fpu_from_isa): New function.
	(arm_declare_function_name): Use it to get the name for the FPU.

From-SVN: r243711

Now that we can describe the FPU with the standard ISA bits we need to
initialize them.  However, the FPU settings can be changed with target build
attributes, so we also need to reset them if things change.  This requires
a bit of juggling about with the existing code to ensure that the active
target is reconfigured after each change to the target options.

	* arm-protos.h: Include sbitmap.h

Similar to the new CPU and architecture ISA feature lists, we now add
similar capabilities to each FPU description.  We don't use these yet,
that will come in later patches.  These follow the same style as the
newly modified flag sets, but use slightly different defaults that
more accurately reflect the ISA specifications.

	* arm-isa.h (isa_feature): Add bits for VFPv4, FPv5, fp16conv,
	fP_dbl, fp_d32 and fp_crypto.
	(ISA_ALL_FPU): Add all the new bits.

From-SVN: r243709

Similar to the main ISA, we convert the FPU revision into a set of feature
bits.  This permits a more complex set of capability relationships to be
expressed more easily.  For now we continue to use the traditional bitmasks.

	* arm.h (FPU_FL_VFPv2) New feature bit.
	(FPU_FL_VFPv3, FPU_FL_VFPv4, FPU_FL_VFPv5, FPU_FL_ARMv8): Likewise.
	(FPU_VFPv2, FPU_VFPv3, FPU_VFPv4, FPU_VFPv5, FPU_ARMv8): New helper

Remove the VFP_REGS field by converting its meanings into flag
attributes.  The new flag attributes build on each other describing
increasing capabilities.  This allows us to do a better job when
inlining functions with differing requiremetns on the fpu environment:
we can now inline A into B if B has at least the same register set
properties as B (previously we required identical register set
properties).

The arm_fp_model enumeration type has only had one useful value since

This converts the recently added implicit -mthumb support code to use
the new data structures.  Since we have a very simple query and no

This patch finishes the job of removing insn_flags and moves the logic
over to using the new data structures.  I've added a new boolean
variable to detect when we have ARMv7ve-like capabilities and thus
have 64-bit atomic operations since that would be a complex query and
expensive to do in full.  It might be better to add a specific bit to
the ISA data structures to indicate this capability directly.

	* arm-protos.h (insn_flags): Delete declaration.
	(arm_arch7ve): Declare.
	* arm.c (insn_flags): Delete.
	(arm_arch7ve): New variable.

This patch uses the new ISA data structure to determine which builtins
to add.  It entirely eliminates the need for insn_flags to be a global
variable, but we're about to delete that in the following patches, so
for now we leave it as a global.

	* arm-builtins.c: Include sbitmap.h.
	(def_mbuiltin): Change first parameter to a flag bit.  Use it to test

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

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.

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.

From-SVN: r243698

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.
