Empirically, the runtime JIT produces slightly better code when > starting with IR that was optimized at -O1. Higher optimization levels tend > to bloat the code. > {quote} > This evaluation was done with LLVM 3.3. We're now on LLVM 5, and this > evaluation may no longer hold. Revisit whether this makes sense or whether > another option (O2, Os, O3) may make more sense. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
