++
++;; This automaton provides a pipeline description for the Marvell
++;; 2850 core.
++;;
++;; The model given here assumes that the condition for all conditional
++;; instructions is "true", i.e., that all of the instructions are
++;; actually executed.
++
++(define_automaton "marvell_f_vfp")
++
++;; This is a single-issue VFPv2 implementation with the following execution
++;; units:
++;;
++;; 1. 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 total time
++;; for a multiply-accumulate instruction to pass through the execution
++;; units is hence eight cycles.
++;;
++;; We do not need to explicitly model the add buffer because it can
++;; always issue the instruction at the head of its FIFO (due to the above
++;; priority rule) and there are more spaces in the add buffer (six) than
++;; there are stages (four) in the multiplication unit.
++;;
++;; Two instructions may be retired at once from the head of an 8-entry
++;; reorder buffer. Data from these first two instructions only may be
++;; forwarded to the inputs of the issue unit. We assume that the
++;; pressure on the reorder buffer will be sufficiently low that every
++;; instruction entering it will be eligible for data forwarding. Since
++;; data is forwarded to the issue unit and not the execution units (so
++;; for example single-cycle instructions cannot be issued back-to-back),
++;; the latencies given below are the cycle counts above plus one.

++When generating position-independent code for ColdFire, generate code
++that works if the GOT has more than 8192 entries. This code is
++larger and slower than code generated without this option. On M680x0
++processors, this option is not needed; @option{-fPIC} suffices.
++
++GCC normally uses a single instruction to load values from the GOT@.
++While this is relatively efficient, it only works if the GOT
++is smaller than about 64k. Anything larger causes the linker
++to report an error such as:
++
++@cindex relocation truncated to fit (ColdFire)
++@smallexample
++relocation truncated to fit: R_68K_GOT16O foobar
++@end smallexample
++
++If this happens, you should recompile your code with @option{-mxgot}.
++It should then work with very large GOTs. However, code generated with
++@option{-mxgot} is less efficient, since it takes 4 instructions to fetch
++the value of a global symbol.
++
++Note that some linkers, including newer versions of the GNU linker,
++can create multiple GOTs and sort GOT entries. If you have such a linker,
++you should only need to use @option{-mxgot} when compiling a single
++object file that accesses more than 8192 GOT entries. Very few do.

++ delete, rather than "foo.o".
++
++ Unfortunately, Eclipse's makefile generators use the "-ofoo.o"

++ use "-o foo.o", the "-ofoo.o" form is used in practice.
++
++ See this email thread for additional information:
++
++ http://gcc.gnu.org/ml/gcc/2008-07/msg00395.html
++
++ Therefore, we define SWITCHES_NEED_SPACES to include "o" by
++ default. This causes "-ofoo.o" to be split into "-o foo.o" during
++ the initial processing of the command-line, before being seen by
++ the specs machinery.
++
++ A risk of this change is that tools which *require* the "-ofoo.o"
++ form will no longer work. However, we know of no such tools, and
++ they would not have worked with the "-o foo.o" form anyhow.
++
++ If this general strategy is acceptable upstream, the best approach
++ might be simply to eliminate this macro, since the only definitions
++ in target files are also to the value "o". */

++/* This pass finds loop indices that are declared as
++ shorter-than-word-size and replaces them with word-sized loop
++ indices. (It assumes that word-sized quantities are the most
++ efficient type on which to do arithmetic.) 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. */

++/* Converting static function-local variables to automatic variables.
++
++ The motivating example is a function like:
++
++ void
++ foo (unsigned n)
++ {
++ static int var;
++ unsigned i;
++
++ for (i = 0; i != n; i++)
++ {
++ var = ...
++
++ do other things with var...
++ }
++ }
++
++ Because VAR is static, doing things like code motion to loads and
++ stores of VAR is difficult. Furthermore, accesses to VAR are
++ inefficient. This pass aims to recognize the cases where it is not
++ necessary for VAR to be static and modify the code so that later
++ passes will do the appropriate optimizations.
++
++ The criteria for a static function-local variable V in a function F
++ being converted to an automatic variable are:
++
++ 1. F does not call setjmp; and
++ 2. V's address is never taken; and
++ 3. V is not declared volatile; and
++ 4. V is not used in any nested function;
++ 5. V is not an aggregate value (union, struct, array, etc.); and
++ 6. Every use of V is defined along all paths leading to the use.
++
++ NOTE: For ease of implementation, we currently treat a function call
++ as killing all previous definitions of static variables, since we
++ could have:
++
++ static void
++ foo (...)
++ {
++ static int x;
++
++ x = ...; (1)
++
++ f (...); (2)
++
