Original Path: sml/trunk/src/compiler/CodeGen
        All pseudo-ops emitted before the first segment declaration
such as TEXT, DATA, and BSS directives are assumed to be global
declarations and are emitted first in the assembly file. This is
useful in a number of situations where one has pseudo-ops that are not
specific to any segment, and also works around the constraint that one
cannot have client pseudo-ops in the TEXT segment.

        Because no segment is associated with these declarations it is
an error to allocate any space or objects before the first segment
directive and an exception will be raised. However, we cannot make
this check for client pseudo-ops.

        These top level declarations are a field in the CFG graph_info.
In theory you can continue to add to this field after the CFG has been
built -- provided you know what you are doing;-)

Edge colors  during graphical viewing is based on

Revision 1168 - Directory Listing
Modified Fri Mar 22 19:19:32 2002 UTC (17 years, 8 months ago) by george
Original Path: sml/trunk/src/compiler/CodeGen
Implemented the Ball-Larus branch prediction-heuristic, and
incorporated graphical viewers for control flow graphs.

Ball-Larus Heuristic:
---------------------
See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.

By design it uses the Dempster-Shafer theory for combining
probabilities.  For example, in the function:

    fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)

the ball-larus heuristics predicts that the n=0 is unlikely
(OH-heuristic), and the 'then' branch is unlikely because of the
RH-heuristic -- giving the 'then' branch an even lower combined
probability using the Dempster-Shater theory.

Finally, John Reppy's loop analysis in MLRISC, further lowers the
probability of the 'then' branch because of the loop in the else
branch.


Graphical Viewing:
------------------
I merely plugged in Allen's graphical viewers into the compiler. The
additional code is not much. At the top level, saying:

	Control.MLRISC.getFlag "cfg-graphical-view" := true;

will display the graphical view of the control flow graph just before
back-patching.  daVinci must be in your path for this to work. If
daVinci is not available, then the default viewer can be changed
using:

	Control.MLRISC.getString "viewer"

which can be set to "dot" or "vcg" for the corresponding viewers. Of
course, these viewers must be in your path.

The above will display the compilation unit at the level of clusters,
many of which are small, boring, and un-interesting. Also setting:

	Control.MLRISC.getInt "cfg-graphical-view_size"

will display clusters that are larger than the value set by the above.

Revision 1133 - Directory Listing
Modified Tue Mar 12 03:56:23 2002 UTC (17 years, 9 months ago) by george
Original Path: sml/trunk/src/compiler/CodeGen
Tested the jump chain elimination on all architectures (except the
hppa).  This is on by default right now and is profitable for the
alpha and x86, however, it may not be profitable for the sparc and ppc
when compiling the compiler.

The gc test will typically jump to a label at the end of the cluster,
where there is another jump to an external cluster containing the actual
code to invoke gc. This is to allow factoring of common gc invocation
sequences. That is to say, we generate:

	f:
	   testgc
	   ja	L1	% jump if above to L1

	L1:
	   jmp L2


After jump chain elimination the 'ja L1' instructions is converted to
'ja L2'. On the sparc and ppc, many of the 'ja L2' instructions may end
up being implemented in their long form (if L2 is far away) using:

	jbe	L3	% jump if below or equal to L3
        jmp 	L2
     L3:
	...


For large compilation units L2  may be far away.

Original Path: sml/trunk/src/compiler/CodeGen
Tested the weighted block placement optimization on all architectures
(except the hppa) using AMPL to generate the block and edge frequencies.
Changes were required in the machine properties to correctly
categorize trap instructions. There is an MLRISC flag
"weighted-block-placement" that can be used to enable weighted block
placement, but this will be ineffective without block/edge
frequencies (coming soon).

Revision 1116 - Directory Listing
Modified Tue Mar 5 23:17:18 2002 UTC (17 years, 9 months ago) by george
Original Path: sml/trunk/src/compiler/CodeGen
In order to support the block placement optimization, the first
cluster that is generated (called the linkage cluster) contains a jump
to the entry point for the compilation unit. The linkage cluster
contains only one 'function', so block placement will have no effect on
the linkage cluster itself, but all the other clusters have full
freedom in the manner in which they reorder blocks or functions.

On the x86 the typical linkage code that is generated is:
   ----------------------
	.align 2
   L0:
        addl    $L1-L0, 72(%esp)
        jmp     L0


        .align  2
   L1:
   ----------------------

72(%esp) is the memory location for the stdlink register. This
must contain the address of the CPS function being called. In the
above example, it contains the address of  L0; before
calling L1 (the real entry point for the compilation unit), it
must contain the address for L1, and hence

	addl $L1-L0, 72(%esp)

I have tested this on all architectures except the hppa.The increase
in code size is of course negligible.

Original Path: sml/trunk/src/compiler/CodeGen
	Removed the native COPY and FCOPY instructions
	from all the architectures and replaced it with the
	explicit COPY instruction from the previous commit.

	It is now possible to simplify many of the optimizations
	modules that manipulate copies. This has not been
	done in this change.

Revision 1003 - Directory Listing
Modified Fri Dec 7 02:45:32 2001 UTC (18 years ago) by george
Original Path: sml/trunk/src/compiler/CodeGen
Changed the representation of instructions from being fully abstract
to being partially concrete. That is to say:

  from
	type instruction

  to
	type instr				(* machine instruction *)

	datatype instruction =
	    LIVE of {regs: C.cellset, spilled: C.cellset}
          | KILL of {regs: C.cellset, spilled: C.cellset}
          | COPYXXX of {k: CB.cellkind, dst: CB.cell list, src: CB.cell list}
          | ANNOTATION of {i: instruction, a: Annotations.annotation}
          | INSTR of instr

This makes the handling of certain special instructions that appear on
all architectures easier and uniform.

LIVE and KILL say that a list of registers are live or killed at the
program point where they appear. No spill code is generated when an
element of the 'regs' field is spilled, but the register is moved to
the 'spilled' (which is present, more for debugging than anything else).

LIVE replaces the (now deprecated) DEFFREG instruction on the alpha.
We used to generate:

	DEFFREG f1
	f1 := f2 + f3
        trapb

but now generate:

	f1 := f2 + f3
	trapb
	LIVE {regs=[f1,f2,f3], spilled=[]}

Furthermore, the DEFFREG (hack) required that all floating point instruction
use all registers mentioned in the instruction. Therefore f1 := f2 + f3,
defines f1 and uses [f1,f2,f3]! This hack is no longer required resulting
in a cleaner alpha implementation. (Hopefully, intel will not get rid of
this architecture).

COPYXXX is intended to replace the parallel COPY and FCOPY  available on
all the architectures. This will result in further simplification of the
register allocator that must be aware of them for coalescing purposes, and
will also simplify certain aspects of the machine description that provides
callbacks related to parallel copies.

ANNOTATION should be obvious, and now INSTR represents the honest to God
machine instruction set!

The <arch>/instructions/<arch>Instr.sml files define certain utility
functions for making porting easier -- essentially converting upper case
to lower case. All machine instructions (of type instr) are in upper case,
and the lower case form generates an MLRISC instruction. For example on
the alpha we have:

  datatype instr =
     LDA of {r:cell, b:cell, d:operand}
   | ...

  val lda : {r:cell, b:cell, d:operand} -> instruction
    ...

where lda is just (INSTR o LDA), etc.

1. X86 fixes/changes

   a.  The old code generated for SETcc was completely wrong.
       The Intel optimization guide is VERY misleading.

2. ALPHA fixes/changes

   a.  Added the instructions LDBU, LDWU, STB, STW as per Fermin's suggestion.
   b.  Added a new mode byteWordLoadStores to the functor parameter to Alpha()
   c.  Added reassociation code for address computation.

1. X86 fixes/changes

   a.  x86Rewrite bug with MUL3 (found by Lal)
   b.  Added the instructions FSTS, FSTL

2. PA-RISC fixes/changes

   a.  B label should not be a delay slot candidate!  Why did this work?
   b.  ADDT(32, REG(32, r), LI n) now generates one instruction instead of two,
       as it should be.
   c.  The assembly syntax for fstds and fstdd was wrong.
   d.  Added the composite instruction COMICLR/LDO, which is the immediate
       operand variant of COMCLR/LDO.

3. Generic MLRISC

   a.  shuffle.sml rewritten to be slightly more efficient
   b.  DIV bug in mltree-simplify fixed (found by Fermin)

4. Register Allocator

   a.  I now release the interference graph earlier during spilling.
       May improve memory usage.

Original Path: sml/trunk/src/compiler/CodeGen

More assembly output problems involving the indexed addressing mode
on the x86 have been found and corrected. Thanks to Fermin Reig for the
fix.

The interface and implementation of the register allocator have been changed
slightly to accommodate the possibility to skip the register allocation
phases completely and go directly to memory allocation.  This is needed
for C-- use.

This fix only affects the x86 assembly output.
