Addition/subtraction unit; takes three cycles, pipelined. ++;; 2. Multiplication unit; takes four cycles, pipelined. ++;; 3. Add buffer, used for multiply-accumulate (see below). ++;; 4. Divide/square root unit, not pipelined. ++;; For single-precision: takes sixteen cycles, can accept another insn ++;; after fifteen cycles. ++;; For double-precision: takes thirty-one cycles, can accept another insn ++;; after thirty cycles. ++;; 5. Single-cycle unit, pipelined. ++;; This does absolute value/copy/negate/compare in one cycle and ++;; conversion in two cycles. ++;; ++;; When all three operands of a multiply-accumulate instruction are ready, ++;; one is issued to the add buffer (which can hold six operands in a FIFO) ++;; and the two to be multiplied are issued to the multiply unit. After ++;; four cycles in the multiply unit, one cycle is taken to issue the ++;; operand from the add buffer plus the multiplication result to the ++;; addition/subtraction unit. That issue takes priority over any add/sub ++;; instruction waiting at the normal issue stage, but may be performed in ++;; parallel with the issue of a non-add/sub instruction.

The loop optimization ++ machinery has a difficult time seeing through the casts required to ++ promote such indices to word-sized quantities for memory addressing ++ and/or preserving the semantics of the source language (such as C). ++ The transformation also helps eliminate unnecessary ++ {sign,zero}-extensions required for the same. ++ ++ Although this is most naturally expressed as a loop optimization ++ pass, we choose to place this pass some ways before the loop ++ optimization passes proper, so that other scalar optimizations will ++ run on our "cleaned-up" code. This decision has the negative of ++ requiring us to build and destroy all the loop optimization ++ infrastructure. ++ ++ The algorithm is relatively simple. For each single-exit loop, we ++ identify the loop index variable. If the loop index variable is ++ shorter than the word size, then we have a candidate for promotion. ++ We determine whether the scalar evolution of the loop index fits a ++ particular pattern (incremented by 1, compared against a ++ similarly-typed loop bound, and only modified by a single increment ++ within the loop), as well as examining the uses of the loop index to ++ ensure we are able to safely promote those uses (e.g. the loop index ++ must not be stored to memory or passed to function calls). If these ++ conditions are satisfied, we create an appropriate word-sized type ++ and replace all uses and defs of the loop index variable with the new ++ variable. */ ++ ++#include "config.h" ++#include "system.h" ++#include "coretypes.h" ++#include "tm.h" ++ ++#include "toplev.h" ++#include "rtl.h" ++#include "tm_p.h" ++#include "hard-reg-set.h" ++#include "obstack.h" ++#include "basic-block.h" ++#include "pointer-set.h" ++#include "intl.h" ++ ++#include "tree.h" ++#include "tree-gimple.h" ++#include "hashtab.h" ++#include "diagnostic.h" ++#include "tree-flow.h" ++#include "tree-dump.h" ++#include "cfgloop.h" ++#include "flags.h" ++#include "timevar.h" ++#include "tree-pass.h" ++#include "tree-chrec.h" ++#include "tree-scalar-evolution.h" ++#include "tree-inline.h" ++ ++struct promote_info { ++ /* The loop being analyzed. */ ++ struct loop *loop; ++ ++ /* The COND_EXPR controlling exit from the loop. */ ++ tree exit_expr; ++ ++ /* The loop index variable's SSA_NAME that is defined in a phi node in ++ LOOP->HEADER.
