Compile a custom numerical loop

Build native CPU user functions and a checked fixed array transformation, then compare the same source through interpreted execution.

Make it your experiment.

Use the matching development source-build compiler SDK and C++20 toolchain. Save this program as examples/native_numeric.aner inside a folder for your experiment. Open a terminal in that folder, then check, build and execute the compiled program.

Choose fresh output paths and retain the generated C++ and JSON build manifest. On Windows, choose an .exe output and use the shell’s executable syntax. Building and the information command start no tasks.

aner check examples/native_numeric.aner
aner build examples/native_numeric.aner -o native-numeric
./native-numeric --aner-native-info
./native-numeric

Windows PowerShell:

aner check examples/native_numeric.aner
aner build examples/native_numeric.aner -o native-numeric.exe
.\native-numeric.exe --aner-native-info
.\native-numeric.exe

Select the matching aner compiler and SDK described in the native build guide; downloaded runtime packages do not provide a usable native SDK.

Requires the matching development source build compiler SDK and C++20 toolchain for native compilation. Downloaded runtime packages do not include a usable native compiler SDK. The interpreted source path remains available with the documented language subset.

This numerical example uses the development source-build compiler SDK. Retain its source, generated C++, build manifest and execution observations together when comparing results.
