Check IBM's RISC research with PL/8, before they decided to create Aix instead.

There is plenty more, however I think you can already lose yourself in such information. :)

Interesting. I remember Jon Bentley [1] mentions BLISS multiple times in his book Writing Efficient Programs.
The book is a gold mine of software performance tuning techniques (with recommendations on when to use them or not), organized in the form of many numbered and well-named "rules" (so that you can remember when to apply them) about saving time or space, or trading space for time or vice versa, all with plenty of examples and "war stories". The book also talks about working at many levels of the stack (although most of the focus is at the level of program code), all the way from hardware up to algorithms.

I took a brief look at the BLISS language, and I have to say that it does seem a bit verbose, though in general, in the larger scheme of things, that may not matter, given other qualities of a language, or may even be an advantage over more cryptic or concise languages.
Luckily many of the same books and papers, now live on as facsimle copies on bitsavers, archive and many other Internet and Faculty repositories.
Burroughs, Xerox PARC, ETHZ, TI, Genera, VMS, Lisa, Constellation, SOLO, SPIN and plenty others are available for systems programming archeology.
