     Bug fixes and improvements to x86 and cfg

Revision 1143 - Directory Listing
Modified Thu Mar 14 15:35:19 2002 UTC (17 years, 7 months ago) by jhr
  Allen's fixes to maintain frequency information.

Revision 1142 - Directory Listing
Modified Wed Mar 13 22:25:37 2002 UTC (17 years, 7 months ago) by leunga

    X86 code generator did not correctly signal the ra to run.

Revision 1136 - Directory Listing
Modified Tue Mar 12 19:44:02 2002 UTC (17 years, 7 months ago) by george
Integrated jump chaining and static block frequency into the
compiler. More details and numbers later.

Revision 1133 - Directory Listing
Modified Tue Mar 12 03:56:23 2002 UTC (17 years, 7 months ago) by george
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.

Revision 1117 - Directory Listing
Modified Wed Mar 6 15:29:24 2002 UTC (17 years, 7 months ago) by jhr
  Uncommented support for FCMP in mltree-gen.sml (this required making
  the Cells structure a functor parameter).

Revision 1116 - Directory Listing
Modified Tue Mar 5 23:17:18 2002 UTC (17 years, 7 months ago) by george
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.

Revision 1108 - Directory Listing
Modified Fri Mar 1 04:46:54 2002 UTC (17 years, 7 months ago) by george

Revision 1085 - Directory Listing
Modified Fri Feb 22 00:15:55 2002 UTC (17 years, 7 months ago) by leunga
    Regenerated these files.  They didn't compile.

Revision 1057 - Directory Listing

  regenerated x86Peephole.sml

Revision 1056 - Directory Listing
Modified Thu Feb 7 21:05:19 2002 UTC (17 years, 8 months ago) by jhr
  Use isZeroLE in the definition of isZero.

Revision 1055 - Directory Listing
Modified Thu Feb 7 20:38:59 2002 UTC (17 years, 8 months ago) by george
Compilers that generate assembly code may produce  global labels
whose value is resolved at link time. The various peephole optimization
modules did not take this in account.

TODO. The Labels.addrOf function should really return an option
type so that clients are forced to deal with this issue, rather
than an exception being raised.

Revision 1053 - Directory Listing
Modified Wed Feb 6 19:11:13 2002 UTC (17 years, 8 months ago) by george
   Pulled out various utility modules that were embedded in the modules
   of the register allocator. I need these modules for other purposes, but
   they are not complete enough to put into a library (just yet).

Revision 1052 - Directory Listing
Modified Wed Feb 6 04:04:48 2002 UTC (17 years, 8 months ago) by george
  A bug fix from Allen.

  A typo causes extra fstp %st(0)'s to be generated at compensation
edges, which might cause stack underflow traps at runtime.  This
occurs in fft where there are extraneous fstps right before the 'into'
trap instruction (in this case they are harmless since none of the
integers overflow.)

Revision 1043 - Directory Listing
Modified Mon Jan 28 21:26:03 2002 UTC (17 years, 8 months ago) by jhr
  Added hooks for parameter-area management by client to CCalls API.
  Currently, these hooks are not being used.

Revision 1033 - Directory Listing
Modified Thu Jan 24 05:45:18 2002 UTC (17 years, 8 months ago) by george
   There is a dramatic simplification in the interface to the
   register allocator for RISC architectures as a result of making
   parallel copy instructions explicit.

Revision 1032 - Directory Listing
Modified Tue Jan 22 16:59:16 2002 UTC (17 years, 8 months ago) by blume

Revision 1024 - Directory Listing
Modified Thu Jan 17 19:30:59 2002 UTC (17 years, 9 months ago) by jhr
  Added Allen's fix for the FP register allocator.

Revision 1017 - Directory Listing
Modified Wed Jan 16 14:48:16 2002 UTC (17 years, 9 months ago) by george
  fixed various bugs with emitting pseudo-ops

Revision 1016 - Directory Listing
Modified Tue Jan 15 23:10:06 2002 UTC (17 years, 9 months ago) by george
1. Since COPY instructions are no longer native to the architecture,
   a generic functor can be used to implement the expandCopies function.

2. Allowed EXPORT and IMPORT pseudo-op declarations to appear inside a
   TEXT segment.

Revision 1012 - Directory Listing
Modified Tue Jan 15 16:16:39 2002 UTC (17 years, 9 months ago) by george
  added BSS and SPACE as basic pseudo-ops

Revision 1009 - Directory Listing
Modified Wed Jan 9 19:44:22 2002 UTC (17 years, 9 months ago) by george
	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 1005 - Directory Listing
Modified Sat Dec 8 07:24:04 2001 UTC (17 years, 10 months ago) by leunga

    Updated peephole modules to match latest MLTREE and instruction
    representation.

Revision 1003 - Directory Listing
Modified Fri Dec 7 02:45:32 2001 UTC (17 years, 10 months ago) by george
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.

Modified Tue Nov 27 06:28:37 2001 UTC (17 years, 10 months ago) by leunga

1. Made the stuff in MLRISC/Tools compile with the new pseudo ops changes.
2. Packaged the stuff in MLRISC/Tools as a library during installation.

Revision 984 - Directory Listing
Modified Wed Nov 21 19:00:08 2001 UTC (17 years, 10 months ago) by george
  Implemented a complete redesign of MLRISC pseudo-ops. Now there
  ought to never be any question of incompatabilities with
  pseudo-op syntax expected by host assemblers.

  For now, only modules supporting GAS syntax are implemented
  but more should follow, such as MASM, and vendor assembler
  syntax, e.g. IBM as, Sun as, etc.

Revision 583 - Directory Listing
Modified Thu Mar 23 21:52:30 2000 UTC (19 years, 6 months ago) by leunga

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.

Revision 579 - Directory Listing
Modified Wed Mar 22 06:33:08 2000 UTC (19 years, 6 months ago) by leunga


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.

Revision 576 - Directory Listing
Modified Fri Mar 10 07:27:16 2000 UTC (19 years, 7 months ago) by leunga

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.

Revision 565 - Directory Listing
Modified Sun Mar 5 04:10:18 2000 UTC (19 years, 7 months ago) by leunga

Fix up a few floating point bugs on the x86 that are discovered by Fermin.
Rewritten the Sethi-Ullman code.  Added new FP instructions to the x86,
including FIxxxx, FCOMxx, and FLDxx.
