Modified Wed Aug 23 23:19:50 2017 UTC (3 years, 1 month ago) by jhr
  More 64-bit cleanup.  Remove information about word sizes
  from CPSREGS signature, since it is redundant (MACH_SPEC
  has the same information).

  Working on 64-bit support.  Trying to make the backend more cleanly
  parameterized by the target machine's word size.  Changed the
  DefaultMachSpec structure to be a functor that is parameterized by
  the ML and machine word sizes.

Original Path: sml/trunk/src/compiler/CodeGen/x86
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 1003 - Directory Listing
Modified Fri Dec 7 02:45:32 2001 UTC (18 years, 9 months ago) by george
Original Path: sml/trunk/src/compiler/CodeGen/x86
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.

Original Path: sml/trunk/src/compiler/CodeGen/x86
  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.

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 (20 years, 6 months ago) by leunga
Original Path: sml/trunk/src/compiler/CodeGen/x86

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.
