I heard tcc builds executables that are not as well optimized as gcc's.
Is this true? As long as tcc won't reduce my execution speed too much I
will still use it, I am just curious.

Certainly it is slower. It does next to no optimization right now, and
it has to reset the registers every instruction IIRC, which is slow.
GCC also replaces some instructions with inline loops--so a memcpy
expands to a full loop, not a function call, and such.

It's only noticable if the program is something like an algorithm, really.
