* Always set image base to 0 for Ghidra * Script improvements Everything here is for Ghidra: * Use `%` instead of f-string (Ghidra still uses python 2.7, meanwhile f-strings were added in 3.6) * Handle errors when applying type (Ghidra throws exception unlike IDA) * Don't trigger decompiler (analysis will be faster) * Revert back string literals * Set image base to zero only for ELF I don't know about PE with Ghidra * Update README for disassemblers * IDA 7.6 required due `ida_ida.inf_is_32bit_exactly()` * Ghidra now don't launch decompiler for whole binary * Set image base to 0 in script Remove %IMAGE_BASE% since we don't use it anymore * Create XREFs for Ghidra Now you can jump from `MethodInfo` to actual method * Fix demangler for Ghidra Ghidra's demangler can process only functions in auto analysis. Now both `TypeInfo` and `MethodInfo` are displayed properly --------- Co-authored-by: commonuserlol <commonuserlol@users.noreply.github.com>
