GCC invokes all the required gnu passes for you with the following utilities.
cpp
The preprocessor which processes
all the header files and macros that your target requires.
gcc
The compiler which produces
assembly language code from the processed C files. For more information,
see Using
GNU CC in GNUPro Compiler Tools.
as
The assembler which produces
binary code from the assembly language code and puts it in an object file.
ld
The linker which binds the
code to addresses, links the startup file and libraries to the object file,
and produces the executable binary image.
There are several machine-independent compiler switches, among which are, notably, -fno-exceptions (for C++), -fritti (for C++) and -T (for linking).
You have four implicit file extensions: .c, .C, .s, and .S. For more information, see Using GNU CC in GNUPro Compiler Tools. 0
