-* pdf.py -- extract assembly format + instruction psuedocode from AMD PDF
-* dsl.py -- helpers for the autogen instruction classes in `__init__.py`. should be standalone with init
-* pcode.py -- psuedocode execution environment. psuedocode should be transformed as little as possible.
-* asm.py -- an asm/disasm function to transform to and from AMD assembly syntax
-* emu.py -- an emulator for RDNA that runs in tinygrad with `AMD=1 MOCKGPU=1 PYTHON_REMU=1`
-
-The code should be as readable and deduplicated as possible. asm and emu shouldn't be required for dsl.
-
-test_emu.py has a good set of instruction tests for the emulation, with USE_HW=1 it will compare to real hardware.
-Whenever an instruction is fixed, regression tests should be added here and confirmed with real hardware.
-
-test_llvm.py tests asm/disasm on the LLVM tests, confirming it behaves the same as LLVM.
-
-tinygrad's dtype tests should pass with and without LLVM. they run in about 12 seconds.

-
-When something is caught by main tinygrad tests, a local regression test should be added to `extra/assembly/amd/test`. While working with tinygrad, you can dump the assembly with `DEBUG=7`. These tests all pass on real hardware, so if a test is failing with `AMD=1 PYTHON_REMU=1 MOCKGPU=1` it's likely because an instruction is emulated incorrectly. You can test without `MOCKGPU=1` to test on real hardware, if it works on real hardware there's a bug in the emulator.
