First standard C code is converted into Blackfin assembly code by the complier, <code>bfin-elf-gcc</code>. The assembler, <code>bfin-elf-as</code>, then takes this code and creates Executable and Linkable Format (ELF) object files. These ELF files are linked together by the utility <code>bfin-elf-ld</code> or included in an archive library by the utility <code>bfin-elf-ar</code>. The ELF files must then be converted into a binary format compatible with uClinux. This conversion is done by the utility <code>bfin-elf-elf2flt</code> which converts ELF files into <code><em>flat</em></code> binary format files. The way in which the compiler controls the assembler, linker, and archiver depends on the source input files and the compiler options used.</p></div></body></html>
