Hi,
Another new feature in Studio 12.4 is better control over the amount of debug information included in the generated object files. The simplest version of this is the new -g1 option which includes minimal debug information. However, we're also provided extensive control over exactly which debug information gets included. The article at https://community.oracle.com/docs/DOC-894097 explains the options in great detail.
Regards,
Darryl.
