On some directives, some clauses accept the use of reserved locators as special identifiers that represent
system storage not necessarily bound to any base language storage item. Reserved locators may only appear
in clauses and directives where they are explicitly allowed and may not otherwise be referenced in the
program. The list of reserved locators is:
omp_all_memory
The reserved locator omp_all_memory is a reserved identifier that denotes a list item treated as having storage that corresponds to the storage of all other objects in memory.
