 <<patch-maxq.tar.gz>> 
Hi,

We at HCL Technologies Pvt. Ltd. Have ported binutils v1.5 for the MAXQ
architechture.

MAXQ is a new high performance RISC architecture from Maxim Integrated
Products & Dallas Semiconductor.
The MAXQ RISC architecture has a new microcontroller core that combines
high performance and low power 
with a variety of complex analog functions.

The MAXQ can be seen as a MOVE driven architecture and the source and
destination operands for the
"MOVE" instruction are the basis for creating instructions and memory
accesses, and triggering hardware 
operations.

	16-bit MAXQ Instruction Word
	FORMAT DESTINATION SOURCE
	  f    ddd dddd    ssss ssss
	  1    Index Mod.  Index Mod.
	  0    Index Mod.  Immediate Data

Initially the MAXQ Arch. has two slightly different versions named
MAXQ10 and MAXQ20. The primary
difference between the MAXQ10 and MAXQ20 options is the standard width
of the working accumulators
 and supporting arithmetic logic unit (ALU).  The MAXQ10 supports 8-bit
(byte-wide) accumulators and 
ALU operations, while the MAXQ20 supports 16-bit (word-wide)
accumulators and ALU operations.

The MAXQ microcontroller uses Peripheral Registers to control and
monitor peripheral 
modules (like General Purpose I/O Module, UART, MAC etc.)

About MAXQ binutils v2.15 port
------------------------------


- The binutils contains support for both MAXQ10 and MAXQ20 versions of
MAXQ. 

- Apart from standard MAXQ Arch. binutils support the   MAXQ2000
variant. Which includes support for
  integrated, in-system-programmable flash memory and a   wide range of
peripherals including an LCD
 driver   supporting up  to x4 multiplexed displays. The MAXQ2000   is
ideally suited for battery-powered,
 portable applications such as blood glucose monitoring, medical
instrumentation, environmental data logging, and   industrial control.

Testing binutils for MAXQ
-------------------------

The testcases for the MAXQ arch. has been integrated into the DEJAGNU
Testsuite.
which will be posted later on.


Configuring and Installing
--------------------------

While configuring the binutils source we need to specify the option
'--enable-bfd-assembler'.
Go to the binutils sources and do:

 > configure --enable-bfd-assembler --target=maxq-coff
 > make
 > make install

Hi Inderpreet,

I tried applying your patch to the current CVS head and got a number
of rejects. In any case the current binutils version is 2.15 and you
claim this to be with respect to binutils v 1.5 . Usually new
contributions are accepted with respect to the current CVS head. So
you might like to rework your patch with respect to the same.

Also since the other thing missing is a set of testcases from the
patch is a set of testcases it would be difficult for anyone to rework
the patches to the current mainline and be sure that those changes did
not break anything.



regards
Ramana

Hi H.J

I got the Idea and am posting the patch for MAXQ form the mainline.
You can get the sources using
cvs -z 9 -d :pserver:anoncvs@sources.redhat.com:/cvs/src co binutils
And then apply the patch.

This patch also includes all the testcases.

Thanks,
Inder

Thanks for doing this.  I have applied your patch, although I had to fix 
up a lot of formatting issues.  Probably as a result of this some of the 
new MAXQ specific GAS and LD tests are failing.  I hope that you will 
find time to investigate these failures and submit patches to fix them.

Cheers
