Wouldn’t just a simple case of bad code generation render little compiler into a toy one?
Repeating others, today’s compilers are really just “optimizing compilers”, there is no room for toying in production environments.

If you find some time to go through gcc bugzilla you'll find shockingly simple snippets of code that miscompiled (often by optimization passes), with fixes never backported to older versions that production environments like RHEL are using.
I still insist that a production grade compiler can’t leave performance on table. Which is where the current battlefield is.
The techniques employed are very similar
in summary, optimizing compilers for c or pascal or zig or rust or whatever can only be used for code where considerations like compatibility, ease of programming, security, and predictability are more important than performance
probably the vast majority of production code is already in python and javascript, which don't even have reasonable compilers at all
Main post is about a C compiler, post I responded is saying
> When your computer was anemic, and could barely do the tasks required for it
which I could only interpret as a machine that can run a single process at a time, so not really about gpus or what.
