jump.c (jmp_uses_reg_or_mem): Deleted unused function.
* jump.c (jmp_uses_reg_or_mem): Deleted unused function.
(find_basic_blocks): Use computed_jump_p to determine if a
particular JUMP_INSN is a computed jump.
* reg-stack.c (find_blocks): Use computed_jump_p to determine
if a particular JUMP_INSN is a computed jump.
* rtlanal.c (jmp_uses_reg_or_mem): New function.
(computed_jump_p): Likewise.
* rtl.h (computed_jump_p): Declare.
* genattrtab.c (pc_rtx): Define and initialize.
* loop.c (loop_optimize): Always determine if the current
function has a computed jump.
(indirect_jump_in_function_p): Use computed_jump_p to determine
if a particular JUMP_INSN is a computed jump.
General (and haifa) cleanups.
