Dr. Christian Giessen aa486f09b0 Add Types 12, 14, 16, 19, 21a, 29, 32, 34, 35 decode

- Type 12: Shift with DM/PM memory access
- Type 14: Shift with Dreg move
- Type 16: Conditional shift
- Type 29: DM/PM read/write with immediate modify
- Type 32: Any Reg <-> DM/PM with DAG postmodify
- Type 34: IO register read/write (both directions)
- Type 35: System control register read/write (both directions)
- Type 21a: MODIFY with immediate offset
- Fix: Move Type 34/35 from b23_22==1 block to b23_22==0
- Fix: Type 12 prefix corrected to bits 23-17 = 0001001
- Zero compiler warnings (except unused xop_shift, now used)
- Full regression test: all 48 isa_test.bin instructions pass

ADSP-219x Radare2 Plugin

Native architecture plugin for disassembling ADSP-219x (including ADSP-2191) 24-bit instructions in radare2 and iaito.

Build & Install

make
make install

Requires: GCC, radare2 >= 5.8.0 (RArchPlugin API).

Usage

r2 -a adsp219x -b 24 firmware.bin

Validation

Compare against the assembler-verified test ROM:

r2 -a adsp219x -b 24 -q -c "pd 48" ../examples/isa_test.bin

The test ROM (isa_test.dsp) was assembled with open21xx and contains known opcodes for all major instruction types.

Coding Standards

This plugin follows the GNU Coding Standards for C source code. No hardcoded absolute paths in any scripts.
