# HIP_ARCHITECTURES

New in version 3.21.

List of GPU architectures to for which to generate device code. Architecture names are interpreted based on `CMAKE_HIP_PLATFORM`.

A non-empty false value (e.g. `OFF`) disables adding architectures. This is intended to support packagers and rare cases where full control over the passed flags is required.

This property is initialized by the value of the `CMAKE_HIP_ARCHITECTURES` variable if it is set when a target is created.

The HIP compilation model has two modes: whole and separable. Whole compilation generates device code at compile time. Separable compilation generates device code at link time. Therefore the `HIP_ARCHITECTURES` target property should be set on targets that compile or link with any HIP sources.

## Examples

    set_property(TARGET tgt PROPERTY HIP_ARCHITECTURES gfx801 gfx900)

Generates code for both `gfx801` and `gfx900`.
