;;; Commentary:
;;;
;;; This module provides helpers for packages targeting AMD GPUs.

;;; Code:

  (or (assoc-ref (package-properties this-package) 'amd-gpu-targets)

(define-syntax-rule (current-amd-gpu-targets-string)
  "Return the list of AMD GPU targets for this package, as a string separated
by \";\".  This is useful for build options like 'AMDGPU_TARGETS' in many
CMake-based packages."
