* tc-alpha.c: Patches to track current minimum alignment to reduce the number of fragments created with frag_align. (alpha_current_align): New static variable. (s_alpha_text): Reset alignment to 0. (s_alpha_data, s_alpha_rdata, s_alpha_sdata): Likewise. (s_alpha_stringer, s_alpha_space): New functions. (s_alpha_cons, alpha_flush_pending_output): Remove functions. (alpha_cons_align): New function to replace both of them. (emit_insn): Only align if alpha_current_align is less than 2; reset alpha_current_align to 2. (s_alpha_gprel32): Likewise. (s_alpha_section): New function. Basically duplicate the other alpha section change hooks. Only define for ELF. (s_alpha_float_cons): Simplify alignment handling. (md_pseudo_table): Only define "rdata" and "sdata" if OBJ_ECOFF. If OBJ_ELF, define "section", "section.s", "sect", and "sect.s". Don't define the s_alpha_cons pseudo-ops. Do define s_alpha_stringer and s_alpha_space pseudo-ops. (alpha_align): Skip if less than current default alignment. Set default alignment. * tc-alpha.h (md_flush_pending_output): Remove. (md_cons_align): Add. * tc-alpha.c: Add oodles of function description comments. (md_bignum_to_chars): Remove; there are no callers. (md_show_usage): Mention some more variants.
