> Hello, we are currently trying to implement an LLVM backend on RISC-V for the GraalVM Native Image project and we run into some issues that are solved by this patch. In summary, we produce LLVM bitcode from Java code and feed it to llc. The problem is that we cannot really control the size of the functions and it can cause branches to out of range locations. However, this issue seems stale and controversial. Is there any news to share?

llc has branchrelaxation, doesn't it solve your problem?
