According to the GraalVM documentation, GraalVM provides its own LLVM toolchain for users. Is this toolchain optimized with PGO? According to my tests, many LLVM-based tools can be optimized with PGO with measurable performance wins. Providing faster toolchain can be beneficial for the GraalVM users.
More information about optimizing LLVM with PGO can be found here:
Additionally, I can suggest evaluating LLVM BOLT usage as a Post-Link Optimization (PLO) step. It can help with optimizing the toolchain even after applying PGO.
