It implements a partial ARMv4 architecture in software.
For code this can accept, use gcc or clang in -march=armv4 mode. Almost all builds of clang but default support --target=armv4-linux regardless of your host platform.
For more information on the ARMv4 architecture, look for documentation on the ARM7 core.
- We are not currently attempting to support Thumb mode
- Only supporting little endian is supported
- For details on the implementation we are aiming for, look at the ARM7TDMI manual
We plan to implement the VFP version 1 for a hardware FPU. For this support add -mfpu=vfp -mfloat-abi=hard to your build command line.
For more information, look at the ARMv5 Architecture Reference Manual.

To compile the code, it requires at least C++17 to work. This includes std::filesystem which is not until GCC 8.
In this project Conan is used for package management. Conan is a portable package manager for C/C++ libraries. It is used to cache all the dependencies needed to build into local directories, without needing to install system packages.
For installation methods of Conan, visit this link. The step-by-step instructions to enable you to build with conan is provided in Conan's website. But in case you would like to see a live demo you can check out this video.
To build the project with conan, you will also need to have CMake with minimum version of 3.8 to support cxx_std_17.
To set the compiler and the compiler version in Conan, edit the ~/.conan/profiles/default file if necessary.
Then in the project directory:
mkdir build && cd build
Conan support is built into the CMakeLists.txt file. You must have conan installed already and need to add appropriate remote:
conan remote add bincrafters https://api.bintray.com/conan/bincrafters/public-conan
cmake ..
If cmake cannot find the version of conan you have installed you can tell it where to find it with:
cmake .. -DCONAN_CMD:PATH=/path/to/conan
After successfully finishing build process, run test to see if everything is work.
You can use ctest
$ ctest
Or make
$ make test
Or execute the tests directly. To do so, simply go to build/bin folder and run the tests.
$ ./constexpr_tests
All tests passed (47 assertions in 21 test cases)
$ ./relaxed_constexpr_tests
All tests passed (47 assertions in 21 test cases)
