Hi all I have to inline some arm instructions with c code.Can any one tell me how to pass the parameters from c code to assembly and take the output.I have a loop in the assembly code and the results are to be stored back to an array in the c code. Can any one suggest me any documents regarding this or any methods to do it. Regards keir

You can create pure assembler source files (*.s files) You can create assembler source files that require CPP processing (*.S files). You can create c source files with inline assembler statements (see above and more ARM specific: http://www.ethernut.de/en/documents/arm-inline-asm.html). Each of them may compile to an object file. The linker forms a binary executable from these object files. So a mixture of object files from *.s, *.S and *.c is possible.
