;; Upon loading a file with the .spv extension into emacs, the file
;; will be disassembled using spirv-dis, and the result colorized with
;; asm-mode in emacs.  The file may be edited within the constraints
;; of validity, and when re-saved will be re-assembled using spirv-as.

;; Note that symbol IDs are not preserved through a load/edit/save operation.
;; This may change if the ability is added to spirv-as.

;; It is required that those tools be in your PATH.  If that is not the case
;; when starting emacs, the path can be modified as in this example:
;; (setenv "PATH" (concat (getenv "PATH") ":/path/to/spirv/tools"))
;;
;; See https://github.com/KhronosGroup/SPIRV-Tools/issues/359
