599ef811c3 * config/tc-tic80.c (build_insn): Handle instructions that have
long (32 bit) PC relative offsets.  Fix places that previously
        misused R_MPPCR for 15 bit offsets to use the new R_MPPCR15W type.
        (md_apply_fix): Add case to handle long PC relative offsets.

* read.c (s_lcomm_internal): Renamed from s_lcomm, added arg to
	flag when alignment is in bytes instead of power of 2, and code to
	use that flag to convert alignment to bytes.
	(s_lcomm, s_lcomm_bytes):  New helpers that call s_lcomm_internal.
	* read.h (s_lcomm_bytes): Add prototype.
	* config/obj-coff.c (write_object_file): If ALIGNMENT_IN_S_FLAGS is
	defined, write alignment to alignment bits in section header s_flags
	rather than the s_align field.

	* config/obj-coff.h (ALIGNMENT_IN_S_FLAGS): Define for TC_TIC80.
	* config/tc-tic80.c (md_pseudo_table): Use s_lcomm_bytes for bss
	pseudo, instead of s_lcomm which wants a power of two for alignment.

e6e676a501 * config/tc-tic80.c (build_insn): Remove "extended" and replace with
"fx" and "fxfrag".  Add "ffrag".  Change code to initialize and use
	the right f/ffrag and fx/fxfrag pairs since instruction may be split
 	across frags.
