TCC does some simple local optimizations (AIUI, some peephole
optimization, and simple intra-statement linear register allocation),
but calling it an "optimizing" compiler in the GCC sense would be too much.

The TCC architecture would require significant changes if one wanted to
make it a true optimizing compiler.

However, TCC-compiled code is likely much faster than anything that the
interpreters (Python, Perl) produce from equivalent code.
