Thanks a lot for taking the time to point these out. They have all
been noted. Unfortunately, I have too many things on my list now. 4829
may be what I tackle first; it may take a while though.
I hope the following is helpful.
Generally, my strengths are in algorithmic/mathematical/numerical
improvements. I have a strong interest in security (both its
"practical" and "theoretical" variants), but with nowhere near the
same level of knowledge.
Clarifications: by algorithmic improvements, I do not usually count
asm code, but make exceptions in some cases. In particular, I have
minimal knowledge of assembly and minimal motivation in learning it.
However, I may examine at some point cases where I am convinced that a
compiler can't do the needful.
By theoretical aspects of security, I refer to defensive programming,
some forms of undefined behavior (e.g rint64_clip, many ubsan
failures), and other such things such as those flagged by Coverity. By
practical aspects of security, I refer to things like fuzzing crashes,
other ubsan failures, and other things flagged by Coverity or found by
