Initial analysis fails while loading main.dol for game G4IP52

[therealjohnpitt]

While trying to setup a project with Shrek Smash n' Crash Racing, the static analysis fails without filling any of the symbols.txt or splits.txt. The game has no ELF/REL, only a DOL file.

WARN module{name=main}: Failed to locate _rom_copy_info

[encounter]

It looks like this game is built with ProDG (a GCC toolchain). This is usually indicated by:

WARN module{name=main}: Failed to locate _rom_copy_info    
WARN module{name=main}: Failed to locate BSS sections    

Unfortunately, decomp-toolkit's analyzer is mostly written with Metrowerks in mind, since the vast majority of games are built with the official toolchain. It's not an easy lift to get ProDG games working.

I'll leave this issue open in case that changes in the future.
