c4x.c (c4x_output_ascii): Restrict line length of output when TI syntax is used. 

2000-01-29 Herman A.J. ten Brugge <Haj.Ten.Brugge@net.HCC.nl>

        * c4x.c (c4x_output_ascii): Restrict line length of output when TI
	syntax is used.
	(c4x_function_prologue): Use regnames intead of float_reg_names when
	TI syntax is used.
	(c4x_function_epilogue): Likewise.
	(c4x_print_operand): Likewise.
	* c4x.h (HOST_WIDE_INT_PRINT_HEX): Redefine.
	* c4x.md (set_high): Disable for TARGET_TI.
