|
|
Follow instructions in COMPILE.TXT for how to compile and run test code.
|
|
|
|
Note: if you find some strange bugs, it is recommended to firstly clean
|
|
the code and try to recompile/reinstall again. This can be done with:
|
|
|
|
$ ./make.sh
|
|
$ sudo ./make.sh install
|
|
|
|
Then test Capstone with cstool, for example:
|
|
|
|
$ cstool x32 "90 91"
|
|
|
|
At the same time, for Java/Ocaml/Python bindings, be sure to always use
|
|
the bindings coming with the core to avoid potential incompatibility issue
|
|
with older versions.
|
|
See bindings/<language>/README for detail instructions on how to compile &
|
|
install the bindings.
|
|
|
|
|
|
Coding style
|
|
------------
|
|
- C code follows Linux kernel coding style, using tabs for indentation.
|
|
- Python code uses 4 spaces for indentation.
|
|
|
|
Updating an Architecture
|
|
------------------------
|
|
|
|
The update tool for Capstone is called `auto-sync` and can be found in `suite/auto-sync`.
|
|
|
|
Not all architectures are supported yet.
|
|
Run `suite/auto-sync/Update-Arch.sh -h` to get a list of currently supported architectures.
|
|
|
|
The documentation how to update with `auto-sync` or refactor an architecture module
|
|
can be found in [docs/AutoSync.md](docs/AutoSync.md).
|
|
|
|
If a module does not support `auto-sync` yet, it is highly recommended to refactor it
|
|
instead of attempting to update it manually.
|
|
Refactoring will take less time and updates it during the procedure.
|
|
|
|
The one exception is `x86`. In LLVM we use several emitter backends to generate C code.
|
|
One of those LLVM backends (the `DecoderEmitter`) has two versions.
|
|
One for `x86` and another for all the other architectures.
|
|
Until now it was not worth it to refactoring this unique `x86` backend. So `x86` is not
|
|
supported currently.
|
|
|
|
Adding an architecture
|
|
----------------------
|
|
|
|
If your architecture is supported in LLVM or one of its forks, you can use `auto-sync` to
|
|
add the new module.
|
|
|
|
<!-- TODO: Move this info to the auto-sync docs -->
|
|
|
|
Obviously, you first need to write all the logic and put it in a new directory arch/newarch
|
|
Then, you have to modify other files.
|
|
(You can look for one architecture such as EVM in these files to get what you need to do)
|
|
|
|
Integrate:
|
|
- cs.c
|
|
- cstool/cstool.c
|
|
- cstool/cstool_newarch.c: print the architecture specific details
|
|
- include/capstone/capstone.h
|
|
- include/capstone/newarch.h: create this file to export all specifics about the new architecture
|
|
|
|
Compile:
|
|
- CMakeLists.txt
|
|
- Makefile
|
|
- config.mk
|
|
|
|
Tests:
|
|
- tests/Makefile
|
|
- tests/test_basic.c
|
|
- tests/test_detail.c
|
|
- tests/test_iter.c
|
|
- tests/test_newarch.c
|
|
- suite/fuzz/platform.c: add the architecture and its modes to the list of fuzzed platforms
|
|
- suite/capstone_get_setup.c
|
|
- suite/MC/newarch/mode.mc: samples
|
|
- suite/test_corpus.py: correspondence between architecture and mode as text and architecture number for fuzzing
|
|
|
|
Bindings:
|
|
- bindings/Makefile
|
|
- bindings/const_generator.py: add the header file and the architecture
|
|
- bindings/python/Makefile
|
|
- bindings/python/capstone/__init__.py
|
|
- bindings/python/capstone/newarch.py: define the python structures
|
|
- bindings/python/capstone/newarch_const.py: generate this file
|
|
- bindings/python/test_newarch.py: create a basic decoding test
|
|
- bindings/python/test_all.py
|
|
|
