Ask HN: Testing AST or assembly output for a compiler
2 by backslash_16 | 0 comments on Hacker News.
Hi Hacker News, I'm working on a c compiler from scratch and am in a bit of a deadzone figuring out how I can test the generated AST and assembly output. I'm specifically having a hard time finding something that is viable for a one person project and which is also useful. I did some research on Clang and saw they use a custom Filecheck library. This looks incredible for a production grade compiler but for mine I'm not sure if I want to put in all of the effort (especially because my host language F# doesn't have a Filecheck lib and I would have to re-create it). Same with the AST - the best I can think of is creating the nodes in my host code language. This is verbose. What have you done to test and check your compiler output, any good recommendations for me? I'm happy to research or read anything. Please keep in mind I'm going for a good effort to reward ratio.
