re PR tree-optimization/93098 (ICE with negative shifter)
PR tree-optimization/93098
* match.pd (popcount): For shift amounts, use integer_onep
or wi::to_widest () == cst instead of tree_to_uhwi () == cst
tests. Make sure that precision is power of two larger than or equal
to 16. Ensure shift is never negative. Use HOST_WIDE_INT_UC macro
instead of ULL suffixed constants. Formatting fixes.
* gcc.c-torture/compile/pr93098.c: New test.

- variadic.
- (aarch64_function_value): Handle SVE predicates, vectors and tuples.
- (aarch64_return_in_memory): Do not return SVE predicates, vectors and
- tuples in memory.
- (aarch64_layout_arg): Take a function_arg_info rather than
- individual properties. Handle SVE predicates, vectors and tuples.
- Raise an error if they are passed to unprototyped functions.
- (aarch64_function_arg): If the silent_p flag is set, suppress the
- usual error about using float registers without TARGET_FLOAT.
- (aarch64_init_cumulative_args): Take a silent_p parameter and store
- it in the cumulative_args structure. Initialize aapcs_nprn and
- aapcs_nextnprn. If the silent_p flag is set, suppress the usual
- error about using float registers without TARGET_FLOAT.
- If the silent_p flag is not set, also raise an error about
- using SVE functions when SVE is disabled.
- (aarch64_function_arg_advance): Update the call to aarch64_layout_arg,
- and call it for SVE functions too. Update aapcs_nprn similarly
- to the other register counts.
- (aarch64_layout_frame): If a big-endian function needs to save
- and restore Z8-Z15, search for a spare predicate that it can use.
- Store SVE predicates at the bottom of the register save area,
- followed by SVE vectors, then followed by the normal slots.
- Keep pointing the hard frame pointer at the base of the normal slots,
- above the SVE vectors. Update the various frame creation and
- tear-down strategies for the new layout, initializing the new
- sve_callee_adjust field. Add an additional layout for frames
- whose saved registers are all SVE registers.
- (aarch64_register_saved_on_entry): Cope with poly_int64 reg_offsets.
- (aarch64_return_address_signing_enabled): Likewise.
- (aarch64_push_regs, aarch64_pop_regs): Update calls to
- aarch64_reg_save_mode.
- (aarch64_adjust_sve_callee_save_base): New function.
- (aarch64_add_cfa_expression): Move earlier in file. Take the
- saved register as an rtx rather than a register number and use
- its mode for the MEM slot.
- (aarch64_save_callee_saves): Remove the mode argument and instead
- use aarch64_reg_save_mode to get the mode of each save slot.
- Add a hard_fp_valid_p parameter. Cope with poly_int64 register
- offsets. Allow GP offsets to be saved at a VL-based offset from
- the stack, handling this case using the frame pointer if available
- or a temporary register otherwise. Use ST1D to save Z8-Z15 for
- big-endian SVE functions; use normal moves for other SVE saves.
- Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
- returns true. Add explicit CFA notes when not storing via the
- stack pointer. Do not try to pair SVE saves.
- (aarch64_restore_callee_saves): Cope with poly_int64 register
- offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;
- use normal moves for other SVE restores. Only add CFA restore notes
- if aarch64_emit_cfi_for_reg_p returns true. Do not try to pair
- SVE restores.
- (aarch64_get_separate_components): Always keep the first SVE save
- in the prologue if we need to use it as a stack probe. Don't allow
- Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
- Likewise the spare predicate register that they need. Update the
- offset calculation to account for the SVE save area. Use the
- appropriate range check for SVE LDR and STR instructions.
- (aarch64_components_for_bb): Cope with poly_int64 reg_offsets.
- (aarch64_process_components): Likewise. Update the offset
- calculation to account for the SVE save area. Only mark the
- save as frame-related if aarch64_emit_cfi_for_reg_p returns true.
- Do not try to pair SVE saves.
- (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
- reg_offsets. When handling the final allocation, expect the
- first SVE register save to be part of the initial allocation
- and for it to act as a probe at SP. Account for the SVE callee
- save area in the dump information.
- (aarch64_expand_prologue): Update the frame diagram. Fold the
- SVE callee allocation into the initial allocation if stack clash
- protection is enabled. Use new variables to track the offset
- of the frame chain (and hard frame pointer) from the current
- stack pointer, and likewise the offset of the bottom of the
- register save area. Update calls to aarch64_save_callee_saves
- and aarch64_add_cfa_expression. Apply sve_callee_adjust before
- saving the FP&SIMD registers. Save the predicate registers.
- (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
- into account when setting the stack pointer from the frame pointer,
- and when deciding whether we can inherit the initial adjustment
- amount from the prologue. Restore the predicate registers after
- the vector registers, then apply sve_callee_adjust, then restore
- the general registers.
- (aarch64_secondary_reload): Don't use secondary SVE reloads
- for VNx16BImode.
- (aapcs_vfp_sub_candidate): Assert that the type is not an SVE type.
- (aarch64_short_vector_p): Return false for SVE types.
- (aarch64_vfp_is_call_or_return_candidate): Initialize *is_ha
- at the start of the function. Return false for SVE types.
- (aarch64_asm_output_variant_pcs): Output .variant_pcs for SVE
- functions too.
- (TARGET_STRICT_ARGUMENT_NAMING): Redefine to request strict naming.
- * config/aarch64/aarch64-sve.md (*aarch64_sve_mov<mode>_le): Extend
- to big-endian targets for bytewise moves.
- (*aarch64_sve_mov<mode>_be): Exclude the bytewise case.
