florian c75486db89 * patch by Nico Erfurth: 
Reorder unaligned Load sequence on ARM

The old version produced code like that:

ldrb rDEST, [rBASE]
ldrb rTemp, [rBASE, #1]
orr  rDEST, rDEST, rTEMP lsl #8 (2 stall cycles)
ldrb rTemp, [rBASE, #2]
orr  rDEST, rDEST, rTEMP lsl #16 (2 stall cycles)
ldrb rTemp, [rBASE, #3]
orr  rDEST, rDEST, rTEMP lsl #24 (2 stall cycles)

This creates a lot of stall-cycles on ARM Implementations with load
delay slots like Marvel Kirkwood or Intel XScale. With the usual up to 2
stall-cycles this code requires a total of 13 cycles (7 instructions + 6 stall
cycles) in best case.

The new code uses a second temp register to avoid the stall cycles.

ldrb rDEST, [rBASE]
ldrb rTemp1, [rBASE, #1]
ldrb rTemp2, [rBASE, #2]
orr  rDEST, rDEST, rTEMP1 lsl #8
ldrb rTemp1, [rBASE, #3]
orr  rDEST, rDEST, rTEMP2 lsl #16
orr  rDEST, rDEST, rTEMP1 lsl #24 (1 stall cycle)

The rescheduling and second register bring the total cycles down to 8.
If a later rescheduling should happen for the last orr it even can go
down to 7.

README.txt 

This directory contains the sources of the Free Pascal Compiler

If you want to compile/modify the compiler, please read first the
programmers manual.

To recompile the compiler, you can use the batch files :
 + mppc386.bat    if you want to build a cross compiler from i386 to m68k
 + mppcsparc      if you want to build a cross compiler from i386 to SPARC
 
 or
Use the make utility as following
  
      make OS_TARGET="compiler OS target" \
      CPU_TARGET="compiler CPU target" \
      FPCCPUOPT="Optimization level" \
      PP="compiler used to compile FPC" \
      COMPILER_OPTIONS="Options passed to compiler" \
      
      
If an option is omitted, then target CPU/OS will be same as current CPU/OS
 
Possibles targets are : linux go32v2 win32 os2 freebsd beos netbsd amiga haiku
atari sunos qnx netware openbsd wdosx palmos macos macosx emx
   
Possible compiler switches (* marks a currently required switch):
  -----------------------------------------------------------------
  GDB*                support of the GNU Debugger
  I386                generate a compiler for the Intel i386+
  x86_64              generate a compiler for the AMD x86-64 architecture
  M68K                generate a compiler for the M68000
  SPARC               generate a compiler for SPARC
  POWERPC             generate a compiler for the PowerPC
  VIS                 generate a compile for the VIS
  DEBUG               version with debug code is generated
  EXTDEBUG            some extra debug code is executed
  SUPPORT_MMX         only i386: releases the compiler switch
                      MMX which allows the compiler to generate
                      MMX instructions
  EXTERN_MSG          Don't compile the msgfiles in the compiler, always
                      use external messagefiles, default for TP
  NOAG386INT          no Intel Assembler output
  NOAG386NSM          no NASM output
  NOAG386BIN          leaves out the binary writer, default for TP
  NORA386DIR          No direct i386 assembler reader
  TEST_GENERIC        Test Generic version of code generator
                      (uses generic RTL calls)
  -----------------------------------------------------------------
  cpuflags            The target processor has status flags (on by default)
  cpufpemu            The target compiler will also support emitting software
                       floating point operations
  cpu64bitaddr        The targets use a 64-bit address space (pointers and
                       the default integer type are 64 bit)
  cpu64bitalu         The target cpu has 64-bit registers available (unless
                       cpu64bitaddr is also defined, pointers and default
                       integer type remain 32 bit, but the cpu can perform
                       64 bit calculations directly without needing helpers)
  -----------------------------------------------------------------

  Required switches for a i386 compiler be compiled by Free Pascal Compiler:
  GDB;I386

to build a compiler to SPARC target using a Win32/i386 you just use :
      make CPU_TARGET=SPARC
