To: J3 07-256r1 From: Bill Long and John Reid Subject: UTI 121 (p212): VOLATILEs and segment ordering Date: 2007 August 8 References: J3/07-007r2 (N1678) Discussion The relaxed rules for segment ordering concerning referencing of VOLATILE scalars is meant to facilitate certain low-level but common constructions (like spin loops). We agree with editor's arguments that scalar elements and components should be treated the same as simple scalars. While reviewing the terminology used in this section we noticed that the first bullet point does not adequately cover non-co-array TARGETs accessed by other images via pointer components of co-arrays. Edits to J3/07-007r2 [212:4] In 8.5.1 Image control statements, paragraph 6, line 4, replace "co-array" by "variable".
