A disassembler and lifter for the CLIPPER architecture, and loaders for CLIPPER ROM images and COFF object/executable files.
This plugin disassembles CLIPPER assembly code and generates LLIL.
The plugin also contains three binary views, the first of which is able to load InterPro computer system boot and flash ROM images. The second is designed to handle COFF executable and object files as used by CLIX (UNIX SYSVR3 for CLIPPER systems). The third binary view handles disk partition images, specifically the REBUILD and FDMDISK boot floppy disk images (and the I/O system monitor, blue screen utility and diagnostic code contained).
The CLIPPER architecture plugin has the following known issues:
- Stack operations using registers other than r15 are not implemented.
- C400 delayed branch instructions are implemented using a number of crude workarounds until the API provides better native support.
The COFF binary view has the following known issues:
- Does not properly support relocatable files or imported symbols.
- Non-exported code symbols do not create functions; this is a workaround until some method of disambiguating functions from simple local labels can be identified.
- Produces quite a lot of logging "noise", dumping information decoded from the input file such as section information and the symbol table. This will be toned down when testing on a broader range of input files has been completed.
