Hello,
This is to introduce a patch to lower the memory footprint of JITed
code by optimizing functions at the function level (i.e. with
function-level optimization passes) as soon as they are generated.
This addresses the code comment inside llvm_optimize_module():
/*
* Do function level optimization. This could be moved to the point where
* functions are emitted, to reduce memory usage a bit.
*/
LLVMInitializeFunctionPassManager(llvm_fpm);
