* final.c (insn_last_address, insn_current_align, uid_align): New variables. (in_align_chain, align_fuzz, align_shrink_fuzz): New functions. (insn_current_reference_address): Likewise. (shorten_branches, final_scan_insn): Implement LABEL_ALIGN, LABEL_ALIGN_AFTER_BARRIER and LOOP_ALIGN target macros. (label_to_alignment): New function. * genattrtab.c (write_test_expr): If one of LABEL_ALIGN, LABEL_ALIGN_AFTER_BARRIER or LOOP_ALIGN is defined, call insn_current_reference_address instead of insn_current_address. (or_attr_value, write_length_unit_log): New functions. (main): Call write_length_unit_log. (write_const_num_delay_slots): Output extra '\n'. * alpha.h (ASM_OUTPUT_LOOP_ALIGN, ASM_OUTPUT_ALIGN_CODE): replace with: (LOOP_ALIGN, ALIGN_LABEL_AFTER_BARRIER). * i386.h, i386/osfrose.h, i386/svr3dbx.h, m68k.h, sparc.h: Likewise. * arc.h, m32r.h (ASM_OUTPUT_LOOP_ALIGN): replace with: (LOOP_ALIGN). * i960.h, m88k.h: (ASM_OUTPUT_ALIGN_CODE): Replace with: (LABEL_ALIGN_AFTER_BARRIER). * ns32k/encore.h, ns32k/merlin.h, ns32k.h, ns32k/sequent.h: Likewise. * ns32k/tek6000.h: Likewise. * i386/gas.h (ASM_OUTPUT_LOOP_ALIGN, ASM_OUTPUT_ALIGN_CODE): Delete. * i386.md (casesi+1): Use ASM_OUTPUT_ALIGN instead of ASM_OUTPUT_ALIGN_CODE.
