Extended Description

A number of options supported by --elf-output-style=LLVM are not implemented for GNU output style, a message is output in these cases which is not too useful for the user. For example use of --elf-linker-options prints:

"printELFLinkerOptions not implemented!"

This is the name of the function. A description of the command line option or missing functionality would be clearer.

Other examples are seen in printCGProfile() and printBBAddrMaps().

Contributor guide

Research direction
Locate the implementations of printELFLinkerOptions, printCGProfile, and printBBAddrMaps in the codebase, and replace the current not implemented messages with descriptive messages indicating the unsupported option and the missing functionality.
