PowerPC Performance Libraries 1.1

This project provides performance optimized library functions for IBM PowerPC
4xx embedded processors. 
The libraries cover floating-point emulation and common C library string and
memory functions.

More information may be found in the Source/doc/ directory.

----------   
2009, November 04 - Recompiled for AmigaOS 4.1 by Max "m3x" Tretene

To install, copy the SDK directory over SDK:

To rebuild the OS4.x version:

cd Source
sh
make -f makefile.os4

The script will build only the string and memory library for the 
440 cpu, since the cpu model used on Sam440ep has a hardware FPU unit.

The link and shared libraries will be placed in SDK:Local/newlib/lib

To rebuild the test executables, enter the Source/stropt/test directory and 
type "make". 

Run the executables linked with ppcstr440 library "t_xxx_new" and compare the 
time needed to complete against the executables linked with the standard SDK 
libraries "t_xxx_old"

7.RAM Disk:test> t_memchr_new 
7.RAM Disk:test> echo $_RunTime
5.661525

7.RAM Disk:test> t_memchr_old   
7.RAM Disk:test> echo $_RunTime
17.627331

(the provided run.sh script doesn't seem work on AOS4)

To link your project with the new library, add -lppcstr440 to LDFLAGS.

ATTENTION: the executables linked with this library will work ONLY on a 440 cpu,

and will crash if run on other cpus (ie G3 / G4)
Add a check in you programm to verify the code is running on a Sam440ep, with
ie:
GetMachineInfo() or GetCPUInfo()
