Anyone know of a collection of &quot;interesting&quot; little code chunks or algorithms for exercising compiler code generation, optimization, etc? Ideally stuff that&#39;s not too big (worst case a few functions, 100-200 lines of code or so), and has interesting code-flow properties, uses more than a handful of registers, does something computationally meaningful, does not depend on IO, (standard) library code, etc. Source in C/Go/Rust style languages a bonus. #Project #Compiler #PLdev

Right now my corpus of code to exercise the compiler is the compiler itself (~5000 lines of code) and an ever-growing library of little test cases (about 1000 lines across 50 tests at the moment), which is a start, but I'd love to have some interesting stuff between those extremes...

@swetland mainly any problem on Rosetta Code, my favorites being Ackerman Peter function and n-queens solvers

@swetland (minimal IO) I found this nice little recursive maze generator which I was using to test an emulator https://github.com/ringtailsoftware/uvm32/blob/main/apps/maze/maze.c

@swetland one i got a lot of mileage out of: compute pi very badly to a requested precision (which doesn't get even a few digits right until 1000 rounds)
