2020-12-31  Richard Sandiford  <richard.sandiford@arm.com>

	* tree-vect-stmts.c (vectorizable_condition): Only nullify cond_expr
	if we've created a new condition.  Don't nullify it if we've decided
	to keep it and then invert the result.

2020-12-31  Richard Sandiford  <richard.sandiford@arm.com>

	* tree-vect-loop-manip.c (create_lcssa_for_virtual_phi): Return
	the incoming virtual operand definition.
	(vect_do_peeling): When vectorizing an epilogue loop, handle the
	case in which the main loop has a virtual phi and the epilogue
	and scalar loops don't.  Restore an earlier comment about the
	update_ssa call.

2019-12-30  Olivier Hainque  <hainque@adacore.com>

	* config/vxworks/stdint.h: New file.  Include _yvals.h

	* config/t-vxworks: Arrange to install the stdint.h wrapper.
	* config.gcc (*-*-vxworks*): Add stdint-gcc.h to $extra_headers
	so it gets copied.  Set use_gcc_stdint to request _not_ crafting
	stdint.h through the common Makefile rules.

            Jerome Lambourg  <labourg@adacore.com>

	* config/t-vxworks: Arrange to alter/restore glimits.h
	before/after stmp-int-hdrs, so it uses a different macro
	name to protect itself against recursive inclusions.

	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

	(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

	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

	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.
