Hi,
I downloaded the gcc source code to find the source code of gcc
implementation of printf function in assembly. But I could not find it.
Does anyone know. Please let me know.

The implementation is in the corresponding C library (such as glibc,
musl, or newlib), not in GCC itself. For glibc, the implementation is
in stdio-common/vfprintf-internal.c, but it is very macro-heavy and tied
to the obsolete libio framework. Other implementations are perhaps more
straightforward.
Thanks,
Florian
