-+
-+;; 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.

-+/* GCC Bugzilla PR11810 indicates that GCC does not correctly handle
-+ "-ofoo.o", in that it records "-ofoo.o" as a temporary file to
-+ delete, rather than "foo.o".
-+
-+ Unfortunately, Eclipse's makefile generators use the "-ofoo.o"
-+ form. See also CS Issue #3433. So, although most users probably
-+ 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)
-+
-+ ... = x; (3)
-+ }
-+
-+ The use at (3) needs to pick up a possible definition made by the
-+ call at (2). If the call at (2) does not call back into 'foo',
-+ then the call is not a killing call. We currently treat it as
-+ though it is. */

-+ It usually pays to define several simpler macros to serve as subroutines for

-+
-+ This macro must exist in two variants: a strict variant and a non-strict
-+ one. The strict variant is used in the reload pass. It must be defined so
-+ that any pseudo-register that has not been allocated a hard register is
-+ considered a memory reference. In contexts where some kind of register is
-+ required, a pseudo-register with no hard register must be rejected.
-+
-+ The non-strict variant is used in other passes. It must be defined to
-+ accept all pseudo-registers in every context where some kind of register is
-+ required.
-+
-+ Compiler source files that want to use the strict variant of this macro
-+ define the macro `REG_OK_STRICT'. You should use an `#ifdef REG_OK_STRICT'
-+ conditional to define the strict variant in that case and the non-strict
-+ variant otherwise.
-+
-+ Subroutines to check for acceptable registers for various purposes (one for
-+ base registers, one for index registers, and so on) are typically among the
-+ subroutines used to define `GO_IF_LEGITIMATE_ADDRESS'. Then only these
-+ subroutine macros need have two variants; the higher levels of macros may be
-+ the same whether strict or not.
-+
-+ Normally, constant addresses which are the sum of a `symbol_ref' and an
-+ integer are stored inside a `const' RTX to mark them as constant.
-+ Therefore, there is no need to recognize such sums specifically as
-+ legitimate addresses. Normally you would simply recognize any `const' as
-+ legitimate.
-+
-+ Usually `PRINT_OPERAND_ADDRESS' is not prepared to handle constant sums that
-+ are not marked with `const'. It assumes that a naked `plus' indicates
-+ indexing. If so, then you *must* reject such naked constant sums as
-+ illegitimate addresses, so that none of them will be given to
-+ `PRINT_OPERAND_ADDRESS'.
-+
-+ On some machines, whether a symbolic address is legitimate depends on the
-+ section that the address refers to. On these machines, define the macro
-+ `ENCODE_SECTION_INFO' to store the information into the `symbol_ref', and
-+ then check for it here. When you see a `const', you will have to look
-+ inside it to find the `symbol_ref' in order to determine the section.
-+
-+ The best way to modify the name string is by adding text to the beginning,
-+ with suitable punctuation to prevent any ambiguity. Allocate the new name
-+ in `saveable_obstack'. You will have to modify `ASM_OUTPUT_LABELREF' to
-+ remove and decode the added text and output the name accordingly, and define
-+ `STRIP_NAME_ENCODING' to access the original name string.
-+
-+ You can check the information stored here into the `symbol_ref' in the
-+ definitions of the macros `GO_IF_LEGITIMATE_ADDRESS' and
-+ `PRINT_OPERAND_ADDRESS'. */

- This patch brings over a few features from MirBSD:
- * -fhonour-copts
- If this option is not given, it's warned (depending
- on environment variables). This is to catch errors
- of misbuilt packages which override CFLAGS themselves.
- * Make -fno-strict-aliasing and -fno-delete-null-pointer-checks
- the default for -O2/-Os, because they trigger gcc bugs
- and can delete code with security implications.
-
- This patch was authored by Thorsten Glaser <tg at mirbsd.de>
- with copyright assignment to the FSF in effect.
