Labels for register-relative addresses
label can represent a named register plus a numeric value. You define these labels in a storage map. They are most commonly used to access data in data sections.
You can use the
EQU directive to define additional register-relative
labels, based on labels defined in storage maps.
Register-relative addresses are not supported in A64 code.
Example of storage map definitions
