Tracing down an AVR bug, I compiled LLVM with debugging and with assertions. Then I made some changes to
src/librustc_codegen_llvm/common.rs. The stage1 build was taking forever, and then I realized that it's likely because of the non-release LLVM.
Is there any great solution to compiling in a reasonable time, or should I switch LLVM to release+debugsymbols?
release + debuginfo, and assertions, should be fine
but also you don't want to build the compiler twice if you're testing around LLVM, unless building rustc itself triggers the bug
