hi all,
Currently i am using GNUARM4.1.1 for ARM7TDMI lpc23xx.I am going to move
to lpc17xx.(CortexM3).Which version of GNUARM i have to use??Can i use
GNUARM4.1.1??I couldn't get detail information from GNUARM document.
Thanks,
GNUARM supports for CortexM3,Thumb2 Instruction

One way to find out is the read the GCC manuals for the various versions. I didn't do this...
As of version 4.4.1 (the document version I have stored locally), the compiler will generate either Thumb1 or Thumb2 depending on -mcpu= and -march= options. So sayeth page 147 of the document (page 159 of the pdf).
So, grab the GCC document for your version and check it out.
The current version of Rowley CrossWorks is using GCC 4.4.3 and I know that Thumb2 works with that because I have been messing around with an STM32F103 which is based on the Cortex M3

The manual for version 4.3.4, which is available at GNU, also indicates that it generates Thumb or Thumb2 depending on the same options.
The manual for version 4.1.2 does not indicate that it supports Thumb2
So, somewhere in the middle which is convenient because the sources at gnuarm.org are for 4.3.2
Since you are using Windows, you could skip cygwin and just use YAGARTO which includes Eclipse and uses GCC 4.4.2.

I don't know when Cortex M3 support was actually added but I have used CodeSourcery gcc version 4.2.3 (Sourcery G++ Lite 2008q1-126) for two years with Luminary and now LPC17XX.
Just set "-mcpu=cortex-m3".

I just installed CodeSourcery 2009Q3 with Windows (it uses GCC 4.4.1) and it works fine with the LP1343 (M3) ... just install it, run your make file from a standard windows command prompt and it should work fine (or at least it does for me). I haven't had time to test out the M0 yet (LPC1114).

I just tested CodeSourcery G++ Lite 2009Q3 with an M0 (LPC1114) and it seems to work fine. The GCC documentation doesn't seem to list cortex-m0 for -mcpu, but it appears to work anyway (http://gcc.gnu.org/onlinedocs/gcc-4.4.3/gcc/ARM-Options.html#ARM-Options)
