slac33

Epson S1C33000 support in Ghidra.

Work in progress. Currently able to disassemble raw binaries fine. Decompilation/P-code implementation needs polishing. Analysis of ELF objects does not work yet due to lack of an architecture-specific parser for relocations, etc.

Not a fork of s1c33_sleigh.

Install

Use gradle to build the extension.

If GHIDRA_INSTALL_DIR is correctly defined, run

gradle

Or, in case it is not defined or you wish to build it for a Ghidra version different than what is specified in GHIDRA_INSTALL_DIR, use

gradle -PGHIDRA_INSTALL_DIR=<Absolute path to Ghidra>

Disassembly syntax

The disassembly syntax is a simplified version inspired by the Capstone syntax and Arm assembly syntax, and is slightly different from Epson's. Specifically:

• Extended instructions do not have the x prefix.
• Registers do not have the % prefix.
• .w suffix are omitted.
• ld.* that loads to RAM is renamed to st (short for store) and with its operands reversed. ld.* that loads from immediate is renamed to mov.
• pushn and popn have the syntax of pushn {:rs} and popn {:rd} to illustrate how the pushed elements look like on the stack from lower to higher address.

If an instruction is delayed, an underscore (_) gets added to the beginning of mnemonic (add -> _add). This is done by Ghidra.
