--- Comment #9 from SK <santoshkumar.a at gmail dot com> 2011-08-25 15:01:26 UTC --- Just for checking i changed the instruction in .s file from "mfcr 27,1" to "mfcr 27" and used the assembler to generate the binary there was no error reported. Now i am confused whether it is fault with assembler if with compiler. Please suggest where to look into.
