[llvm-dev] MCJIT emitting optimization diagnostics on stdout/stderr
Hello, Starting with LLVM 3.8.x, we get some diagnostic printouts when JITting some functions, e.g.: remark: <unknown>:0:0: loop not vectorized: cannot prove it is safe to reorder memory operations Is it normal to get those by default? Is there a well-defined way to disable them? Regards Antoine.

It looks like DK_OptimizationRemarkAnalysisAliasing isn't handled in llvm::isDiagnosticEnabled(), hence those messages are always unconditionally output... Regards Antoine.
