Change the interfaces for backend methods that create statements to
always pass in the enclosing Bfunction for the statement. Having the
function available simplifies things if a temporary variable has to be
created during the construction of a statement.
This also includes a change to the Mark_lvalue_varexprs helper
class to handle indirections on the left hand side of assignments
(e.g. "*x.y = ...").

doesn't support RSC with an immediate.
The negdi2 patterns for ARM and Thumb-2 are duplicated because Thumb-2
doesn't support RSC with an immediate. We can however emulate RSC with
zero using a shifted SBC. If we add this to subsi3_carryin the negdi
patterns can be merged, simplifying things a bit. This should generate
identical code in all cases.

registers.
Thumb uses a special register allocation order to increase the use of low
registers. Oddly enough, LR appears before R12, which means that LR must
be saved and restored even if R12 is available. Swapping R12 and LR means
this simple example now uses R12 as a temporary (just like ARM):
int f(long long a, long long b)
{
if (a < b) return 1;
return a + b;
}

Previously users of mulsidi_600 and umulsidi_600 had to take care of
moving the multiplication result into the final destination themselves
(from the MUL64_OUT_REG register). This commit converts these two
instruction patterns into insn_and_split patterns that now take the
final destination as an extra operand. The insn_and_split patterns
generate the multiplication using two new multiplication instruction
patterns, then generate the move of the result from the MUL64_OUT_REG
register into the final destination.
This is a clean up commit, there should be no user visible changes
after this commit.

compiler: call determine_types even for constant expressions
We need to call determine_types even for constant expressions, since a
constant expression may include code like unsafe.Sizeof(0). Something
needs to determine the type of the untyped 0, and that should be the
determine_types pass.
Implementing that triggered a compiler crash on test/const1.go because
it permitted some erroneous constants to make it all the way to the
backend. Catch that case by checking whether we get a constant
overflow error, and marking the expression invalid if we do. This is
a good change in any case, as previously we reported the same constant
overflow error multiple times, and now we only report it once.
Fixes GCC PR 78763.

(arm_valid_target_attribute_tree): Use the target options for
reconfiguration. Resynchronize after performing override checks.

Now that the isa feature bits are all available in arm_active_target
we can use that for most of the feature tests that are needed.
* arm.h (TARGET_VFPD32): Use arm_active_target.
(TARGET_VFP3): Likewise.
(TARGET_VFP5): Likewise.
(TARGET_VFP_SINGLE): Likewise.
(TARGET_VFP_DOUBLE): Likewise.

(TARGET_FMA): Likewise.
(TARGET_FPU_ARMV8): Likewise.
(TARGET_CRYPTO): Likewise.
(TARGET_NEON): Likewise.
(TARGET_FPU_FEATURES): Delete.

Neon using arm_active_target.

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.

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
(arm_configure_build_target): Make public.
* arm.c (arm_configure_build_target): Now not static.
(arm_valid_target_attribute_rec): Move internal option check to...
(arm_valid_target_attribute_tree0: ... here. Also reconfingure the
active target.
(arm_override_options_after_change): Call arm_configure_build_target.
(isa_all_fpubits): Renamed from isa_fpubits.
(arm_option_restore): New function.
(TARGET_OPTION_RESTORE): Register it.
(arm_configure_build_target): Initialize the FPU capability bits in
the isa.
(arm_option_override): Move the code that forces the setting of the
FPU option before the call to arm_configure_build_target.
* arm.opt (march): Mark as Save.
(mcpu, mtune): Likewise.
* arm-c.c (arm_pragma_target_parse): Reconfigure the build target
after pragmas change the target options.

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.
(ISA_VFPv2, ISA_VFPv3, ISA_VFPv4, ISA_FPv5): New macros.
(ISA_FP_ARMv8, ISA_FP_DBL, ISA_FP_D32, ISA_NEON, ISA_CRYPTO): Likewise.
* arm-fpus.def: Add ISA features to all FPUs.
* arm.h: (arm_fpu_desc): Add new field for ISA bits.
* arm.c (all_fpus): Initialize it.
* arm-tables.opt: Regenerated.

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
macros.
(FPU_DBL, FPU_D32, FPU_NEON, FPU_CRYPTO, FPU_FP16): Likewise.
(TARGET_FPU_REV): Delete.
(TARGET_VFP3): Use feature bits.
(TARGET_VFP5): Likewise.
(TARGET_FMA): Likewise.
(TARGET_FPU_ARMV8): Likewise.
(struct arm_fpu_desc): Delete rev field.
* arm-fpus.def: Delete REV entry, use new feature bits and macros.
* arm.c (all_fpus): Delete rev field.

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).
* arm.h (vfp_reg_type): Delete.
(TARGET_FPU_REGS): Delete.
(arm_fpu_desc): Delete regs field.
(FPU_FL_NONE, FPU_FL_NEON, FPU_FL_FP16, FPU_FL_CRYPTO): Use unsigned
values.
(FPU_FL_DBL, FPU_FL_D32): Define.
(TARGET_VFPD32): Use feature test.
(TARGET_VFP_SINGLE): Likewise.
(TARGET_VFP_DOUBLE): Likewise.
* arm-fpus.def: Update all entries for new feature bits.
* arm.c (all_fpus): Update initializer macro.
(arm_can_inline_p): Remove test on fpu regs.

The arm_fp_model enumeration type has only had one useful value since
the FPA support was removed, and it's no-longer used anywhere. This
patch just cleans that up by removing it.
* arm.h (arm_fp_model): Delete.
From-SVN: r243706

Nothing uses the old feature sets now, so we can delete them entirely.
* arm-cores.def: Remove FLAGS field from all core definitions.
* arm-arches.def: Likewise.
* arm-opts.h (enum processor_type): Remove FLAGS parameter from
ARM_CORES macro.
(arm_arch_core_flags): Likewise, plus ARM_ARCH macro.
* arm-protos.h (FL_*): Delete.
(arm_feature_set): Delete.
(ARM_FSET_*): Delete.
* arm.c (struct processors): Delete flags field.

This converts the recently added implicit -mthumb support code to use
the new data structures. Since we have a very simple query and no
initialized copies of the sbitmaps, for now we simply scan the list of
features to look for the one of interest.
* arm-opts.h (struct arm_arch_core_flag): Add new field ISA.
Initialize it.
(arm_arch_core_flag): Delete flags field.
(arm_arch_core_flags): Don't initialize flags field.
* common/config/arm/arm-common.c (check_isa_bits_for): New function.
(arm_target_thumb_only): Use new isa bits arrays.

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.
(arm_selected_cpu): Delete.
(arm_option_check_internal): Use new ISA bitmap.
(arm_option_override_internal): Likewise.
(arm_configure_build_target): Declare arm_selected_cpu locally.
(arm_option_override): Use new ISA bitmap. Initialize arm_arch7ve.
Rearrange variable intialization by general function.
* arm.h (TARGET_HAVE_LPAE): Use arm_arch7ve.

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
available features in the current target.
(struct builtin_description): Change type of feature field.
(IWMMXT_BUILTIN): Use the isa_features types.
(IWMMXT2_BUILTIN): Likewise.
(IWMMXT_BUILTIN2): Likewise.
(IWMMXT2_BUILTIN2): Likewise.
(CRC32_BUILTIN): Likewise.
(CRYPTO_BUILTIN): Likewise.
(iwmmx_builtin): Likewise.
(iwmmx2_builtin): Likewise.
(arm_iwmmxt_builtin): Check for specific feature bits.

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.
