re PR target/50022 ("incorrect condition in IT block" when building mozilla code base for ARM) 



2011-08-15  Ramana Radhakrishnan  <ramana.radhakrishnan@linaro.org>

	PR target/50022
	* config/arm/arm.c (output_move_double): Add 2 parameters
	to count the number of insns emitted and whether to emit or not.
	Use the flag to decide when to emit and count number of instructions
	that will be emitted.
	Handle case where output_move_double might be called for calculating
	lengths with an invalid constant.
	(arm_count_output_move_double_insns): Define.
	* config/arm/arm-protos.h (arm_count_output_move_double_insns): Declare.
	(output_move_double): Adjust prototype.
	* config/arm/vfp.md ("*movdi_vfp"): Adjust call to
	output_move_double.
	("*movdi_vfp_cortexa8"): Likewise and add attribute
	for ce_count.
	* config/arm/arm.md ("*arm_movdi"): Adjust call to output_move_double.
	("*movdf_soft_insn"): Likewise.
	* config/arm/cirrus.md ("*cirrus_arm_movdi"): Likewise.
	("*cirrus_thumb2_movdi"): Likewise.
	("*thumb2_cirrus_movdf_hard_insn"): Likewise.
	("*cirrus_movdf_hard_insn"): Likewise.
	* config/arm/neon.md (*neon_mov<mode> VD): Likewise.
	* config/arm/iwmmxt.md ("*iwmmxt_arm_movdi"): Likewise.
	("mov<mode>_internal VMMX"): Likewise.
	* config/arm/fpa.md (*movdf_fpa, *thumb2_movdf_fpa): Likewise.
