If split stacks are negatively impacting profiling, debugging, or other compiler development tasks, I have to ask, have we considered optimizing clang stack usage? There are multiple issues: * Clang is a recursive descent parser. This isn't going to change, it just means we can't ignore stack usage. * We use lots of needlessly nested "small" data structures on the stack, which means are stack frames are large * Anecdotally I am told that LLVM is not great at stack coloring This is not a blocking concern, but we should seriously consider doing some builds with -Wframe-larger-than or -Wstack-usage in Sema and Parser. We'd all be happier for it. I had some comments, but overall this seems reasonable. https://github.com/llvm/llvm-project/pull/133173 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
