Um, no. `gcc` is a driver that runs cc1 (a C compiler from the GNU compiler collection), cc1plus (a C++ compiler from the GNU compiler collection), (g)as (an assembler from GNU binutils) and ld (a static linker from GNU binutils) and sometimes other front-ends for other languages, and sometimes other back-ends for other reasons, and sometimes some special middle-ends.

All `gcc` does is parse come command-line options and then invoke other programs to do the actual job of preprocessing, compiling, assembling, and linking.

clang packs all three things into a single executable. GCC however will always call out to external executables for compiler (cc1) and assembler (as)

gcc uses gas (from binutils) as its assembler, unlike clang.
