 The translator accepts a number of reserved names that correspond to SPIR-V
-member decorations.

 None of the special requirements imposed from using the reserved names apply to

+In cases when decoration parameter carried by ``llvm.ptr.annotation`` coalesces

+the value depending on the meaning of the annotation. For example for alignment
+we can chose the biggest alignment specified in LLVM IR:

 During reverse translation, the translator prioritizes reserved names over
 decoration identifiers, even if the member decoration was generated using the
 corresponding decoration identifier. For example, this means that translating
