# Source structure
|
||||
|
||||
Since many source files are automatically generated from ghidra, the file names correspond to the function names inside ghidra, one source file per function.
|
||||
For each required function in the program the file will be either in gh_auto or gh_fix
|
||||
|
||||
## gh_auto
|
||||
|
||||
Contains the decompiled ghidra source files
|
||||
|
||||
## gh_fix
|
||||
|
||||
Contains decompiled source functions, manually fixed up
|
||||
File diff suppressed because it is too large
