rtl.h (insn_first_p): Declare.
* rtl.h (insn_first_p): Declare.
* rtlanal.c (insn_first_p): New function.
* loop.h (varray.h): Include.
(struct induction): Change combined_with to unsigned.
New members derived, ix and last_use.
(reg_iv_type, reg_iv_info): Now varray_type. All references changed.
(REG_IV_TYPE, REG_IV_INFO): Define.
(first_increment_giv, last_increment_giv): Declare.
* loop.c (loop_number_loop_cont): New static variable.
(loop_number_cont_dominator): Likewise.
(reg_iv_type, reg_iv_info): Now varray_type.
(first_increment_giv, last_increment_giv): New variables.
(compute_luids, verify_dominator, find_life_end): New functions.
(cmp_recombine_givs_stats, recombine_givs): Likewise.
(loop_optimize): Allocate loop_number_loop_cont and
loop_number_cont_dominator. Use compute_luids.
(find_and_verify_loops): Initialize loop_number_loop_cont and
loop_number_cont_dominator.
(strength_reduce): Try to find bivs that can be expressed as givs
of another biv, and to convert biv increments into givs.
Call recombine_givs. Handle derived givs.
(record_biv): New argument location. All callers changed.
(record_giv): Initialize derived and last_use fields.
(basic_induction_var): New argument location. All callers changed.
(combine_givs): Don't combine a DEST_REG giv with a DEST_ADDR giv.
Increment combined_with instead of setting to 1.
* unroll.c (derived_regs): New static variable.
(unroll_loop): Initialize it.
Allocate local_regno according to max_reg_num.
(copy_loop_body): Cope with derived givs.
(find_splittable_givs): Check for Givs made from biv increments.
Set derived_regs for givs.
* Makefile.in (stmt.o, loop.o, unroll.o): Depend on loop.h .
