What I wanted to discuss was in terms of reproducibility of tcc compiler

*snip*

The problem is that tcc’s “long double” uses only 10 bytes, but it is stored in 12 bytes, and tcc’s source code does not initialize the extra 2 bytes

Wouldn't a better solution be to change tcc to clear the padding bytes,
which would also help it reproducibly build other software?
