Hi Aram,
i have gone through the a.out file after this error.> that is producing full of arm instructions other than the main
function(which is compiled for -mthumb). where should i change for this corresponding error.
It is not clear what question you are asking here.
Ian has pointed out that you should be compiling your program with the -mthumb-interwork switch specified on the gcc command line.
i have added one new add instruction in thumb mode. based on that
i have written one sample program to emit the corresponding new instruction. gcc works fine. when i assemble the function it emits

Again this is not clear. Do you mean that when the linker is creating the executable that it is inserting some ARM-encoded instructions into the output, or that it is somehow magically transforming your THUMB-encoded instructions into ARM-encoded instructions ?
Perhaps it would help if you could provide a *small* example program and the command lines you use to compile it, as well as description of what is wrong with the resulting executable.
Cheers Nick
