2005-11-14 Jan Beulich <jbeulich@novell.com> * config/tc-ia64.c (md): Rename regsym to indregsym and move it to the end of the structure. (ar): Field regnum is unsigned. (cr): Likewise: (indirect_reg): Likewise. (declare_register_set): Parameter regnum is unsigned. (declare_register): Parameter numregs and base_regnum are unsigned. So is the local loop variable. (md_begin): Restrict scope of local variable regnum, which also is unsigned. Replace loops with function calls where possible. Re-order things so that register groups are kept together. Remove all uses of regsym except for indirect registers. Replace use of regsym by indregsym for indirect registers. (ia64_optimize_expr): Replace use of regsym by indregsym for indirect registers, with appropriate bias.
