Options

re PR target/90096 (Misleading option hint for AVX intrinsics) 

	PR target/90096
	* config/i386/i386.c (ix86_target_string): Add ADD_ABI_P argument, only
	print -m64/-mx32/-m32 if it is true.
	(ix86_debug_options, ix86_function_specific_print): Pass true as
	ADD_ABI_P to ix86_target_string.
	(ix86_expand_builtin): Adjust ix86_target_string caller, pass true as
	ADD_ABI_P only if OPTION_MASK_ISA_64BIT is set in bisa and in that case
	or into it OPTION_MASK_ISA_ABI_64 or OPTION_MASK_ISA_ABI_X32.

	* gcc.target/i386/pr90096.c: New test.
	* gcc.target/i386/pr69255-1.c: Adjust expected diagnostics.
	* gcc.target/i386/pr69255-2.c: Likewise.
	* gcc.target/i386/pr69255-3.c: Likewise.
