Create an offloading section struct used to register this global at runtime.
Type struct __tgt_offload_entry { void *addr; // Pointer to the offload entry info. // (function or global) char *name; // Name of the function or global. size_t size; // Size of the entry info (0 if it a function). int32_t flags; int32_t data; };
M | The module to be used |
Addr | The pointer to the global being registered. |
Name | The symbol name associated with the global. |
Size | The size in bytes of the global (0 for functions). |
Flags | Flags associated with the entry. |
Data | Extra data storage associated with the entry. |
SectionName | The section this entry will be placed at. |
