6322 (aarch64_sve_abi): New function.
6323 (aarch64_sve_argument_p): Likewise.
6324 (aarch64_returns_value_in_sve_regs_p): Likewise.
6325 (aarch64_takes_arguments_in_sve_regs_p): Likewise.
6326 (aarch64_fntype_abi): Check for SVE functions and return the SVE PCS
6327 descriptor for them.
6328 (aarch64_simd_decl_p): Delete.
6329 (aarch64_emit_cfi_for_reg_p): New function.
6330 (aarch64_reg_save_mode): Remove the fndecl argument and instead use
6331 crtl->abi to choose the mode for FP registers. Handle the SVE PCS.
6332 (aarch64_hard_regno_call_part_clobbered): Do not treat FP registers
6333 as partly clobbered for the SVE PCS.
6334 (aarch64_function_ok_for_sibcall): Check whether the two functions
6335 use the same ABI, rather than checking specifically for whether
6336 they're aarch64_vector_pcs functions.
6337 (aarch64_pass_by_reference): Raise an error for attempts to pass
6338 SVE arguments when SVE is disabled. Pass SVE arguments by reference
6339 if there are not enough free registers left, or if the argument is
6341 (aarch64_function_value): Handle SVE predicates, vectors and tuples.
6342 (aarch64_return_in_memory): Do not return SVE predicates, vectors and
6344 (aarch64_layout_arg): Take a function_arg_info rather than
6345 individual properties. Handle SVE predicates, vectors and tuples.
6346 Raise an error if they are passed to unprototyped functions.
6347 (aarch64_function_arg): If the silent_p flag is set, suppress the
6348 usual error about using float registers without TARGET_FLOAT.
6349 (aarch64_init_cumulative_args): Take a silent_p parameter and store
6350 it in the cumulative_args structure. Initialize aapcs_nprn and
6351 aapcs_nextnprn. If the silent_p flag is set, suppress the usual
6352 error about using float registers without TARGET_FLOAT.
6353 If the silent_p flag is not set, also raise an error about
6354 using SVE functions when SVE is disabled.
6355 (aarch64_function_arg_advance): Update the call to aarch64_layout_arg,
6356 and call it for SVE functions too. Update aapcs_nprn similarly
6357 to the other register counts.
6358 (aarch64_layout_frame): If a big-endian function needs to save
6359 and restore Z8-Z15, search for a spare predicate that it can use.
6360 Store SVE predicates at the bottom of the register save area,
6361 followed by SVE vectors, then followed by the normal slots.
6362 Keep pointing the hard frame pointer at the base of the normal slots,
6363 above the SVE vectors. Update the various frame creation and
6364 tear-down strategies for the new layout, initializing the new
6365 sve_callee_adjust field. Add an additional layout for frames
6366 whose saved registers are all SVE registers.
6367 (aarch64_register_saved_on_entry): Cope with poly_int64 reg_offsets.
6368 (aarch64_return_address_signing_enabled): Likewise.
6369 (aarch64_push_regs, aarch64_pop_regs): Update calls to
6370 aarch64_reg_save_mode.
6371 (aarch64_adjust_sve_callee_save_base): New function.
6372 (aarch64_add_cfa_expression): Move earlier in file. Take the
6373 saved register as an rtx rather than a register number and use
6374 its mode for the MEM slot.
6375 (aarch64_save_callee_saves): Remove the mode argument and instead
6376 use aarch64_reg_save_mode to get the mode of each save slot.
6377 Add a hard_fp_valid_p parameter. Cope with poly_int64 register
6378 offsets. Allow GP offsets to be saved at a VL-based offset from
6379 the stack, handling this case using the frame pointer if available
6380 or a temporary register otherwise. Use ST1D to save Z8-Z15 for
6381 big-endian SVE functions; use normal moves for other SVE saves.
6382 Only mark the save as frame-related if aarch64_emit_cfi_for_reg_p
6383 returns true. Add explicit CFA notes when not storing via the
6384 stack pointer. Do not try to pair SVE saves.
6385 (aarch64_restore_callee_saves): Cope with poly_int64 register
6386 offsets. Use LD1D to restore Z8-Z15 for big-endian SVE functions;
6387 use normal moves for other SVE restores. Only add CFA restore notes
6388 if aarch64_emit_cfi_for_reg_p returns true. Do not try to pair
6390 (aarch64_get_separate_components): Always keep the first SVE save
6391 in the prologue if we need to use it as a stack probe. Don't allow
6392 Z8-Z15 saves and loads to be shrink-wrapped for big-endian targets.
6393 Likewise the spare predicate register that they need. Update the
6394 offset calculation to account for the SVE save area. Use the
6395 appropriate range check for SVE LDR and STR instructions.
6396 (aarch64_components_for_bb): Cope with poly_int64 reg_offsets.
6397 (aarch64_process_components): Likewise. Update the offset
6398 calculation to account for the SVE save area. Only mark the
6399 save as frame-related if aarch64_emit_cfi_for_reg_p returns true.
6400 Do not try to pair SVE saves.
6401 (aarch64_allocate_and_probe_stack_space): Cope with poly_int64
6402 reg_offsets. When handling the final allocation, expect the
6403 first SVE register save to be part of the initial allocation
6404 and for it to act as a probe at SP. Account for the SVE callee
6405 save area in the dump information.
6406 (aarch64_expand_prologue): Update the frame diagram. Fold the
6407 SVE callee allocation into the initial allocation if stack clash
6408 protection is enabled. Use new variables to track the offset
6409 of the frame chain (and hard frame pointer) from the current
6410 stack pointer, and likewise the offset of the bottom of the
6411 register save area. Update calls to aarch64_save_callee_saves
6412 and aarch64_add_cfa_expression. Apply sve_callee_adjust before
6413 saving the FP&SIMD registers. Save the predicate registers.
6414 (aarch64_expand_epilogue): Take below_hard_fp_saved_regs_size
6415 into account when setting the stack pointer from the frame pointer,
6416 and when deciding whether we can inherit the initial adjustment
6417 amount from the prologue. Restore the predicate registers after
6418 the vector registers, then apply sve_callee_adjust, then restore
6419 the general registers.
6420 (aarch64_secondary_reload): Don't use secondary SVE reloads
6422 (aapcs_vfp_sub_candidate): Assert that the type is not an SVE type.
6423 (aarch64_short_vector_p): Return false for SVE types.
6424 (aarch64_vfp_is_call_or_return_candidate): Initialize *is_ha
6425 at the start of the function. Return false for SVE types.
6426 (aarch64_asm_output_variant_pcs): Output .variant_pcs for SVE
6428 (TARGET_STRICT_ARGUMENT_NAMING): Redefine to request strict naming.
6429 * config/aarch64/aarch64-sve.md (*aarch64_sve_mov<mode>_le): Extend

35354 * gimple-fold.c (get_range_strlen_tree): Record if the computed
35355 length is optimistic. If it is, then arrange to compute the
35356 conservative length as well.
35358 * gimple-fold.h (get_range_strlen): Update prototype.
35359 * builtins.c (check_access): Update call to get_range_strlen to use
35360 c_strlen_data pointer. Change various variable accesses to instead
35361 pull data from the c_strlen_data structure.
35362 (check_strncat_sizes, expand_builtin_strncat): Likewise.
35363 * calls.c (maybe_warn_nonstring_arg): Likewise.
35364 * tree-ssa-strlen.c (maybe_diag_stxncpy_trunc): Likewise. Reset
35365 minimum length if maximum lengh is unknown.
35366 * gimple-ssa-sprintf.c (get_string_length): Likewise. Drop code
35367 that used c_strlen, it's no longer needed. Restructure slightly.
35368 (format_string): Set unlikely range appropriately.
35369 * gimple-fold.c (get_range_strlen): Update comments. Fix minor
35371 (get_range_strlen): Accept c_strlen_data pointer for external
35372 call sites as well. Pass through to call to internal get_range_strlen.
35373 Adjust minlen, maxlen and maxbound as needed.
35374 (get_maxval_strlen): Update comments.
35375 (gimple_fold_builtin_strlen): Update call to get_range_strlen
35376 to use c_strlen_data pointer. Change variable accesses to instead
35377 use c_strlen_data data members.
35379 * gimple-fold.c (get_range_strlen): Update prototype.
35380 (get_range_strlen_tree): Update prototype. Drop minlen/maxlen
35381 local variables. Use pdata to return information to caller.
35382 Update calls to get_range_strlen. Update pdata->maxbound.
35383 (get_range_strlen -- static version): Similarly.
35384 (get_range_strlen -- extern version): Update for internal
35385 get_range_strlen API change. Convert to external data format.
35386 (get_maxval_strlen): Similarly.
35388 2019-01-01 Jan Hubicka <hubicka@ucw.cz>
35390 * coverage.c (get_coverage_counts): Use current_function_decl.
35391 * profile.c (read_thunk_profile): New function.
35392 (branch_prob): Add THUNK parameter.
35393 * tree-profile.c (tree_profiling): Handle thunks.
35394 * value-prof.c (init_node_map): Handle thunks.
35395 * value-prof.h (branch_prob): Upate prototype.
35396 (read_thunk_profile): Declare.
