hi, thanks for identifying the error. 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. 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 correct opcode. but when i give the same function to the ld it emits full of arm instructions instead of thumb instructions. which routine checks for this corresponding change. thanks in advance ----- Original Message ----- From: "Ian Lance Taylor" <ian@airs.com> To: "aram bharathi" <[EMAIL PROTECTED]> Subject: Re: adding new instruction Date: 12 Feb 2005 21:06:07 -0500
