/* This information must be kept in sync with the _DL_HWCAP_COUNT and

If anything should be added here check whether the size of each string

is still ok with the given array size.
|

|

All the #ifdefs in the definitions are quite irritating but
|

necessary if we want to avoid duplicating the information. There
|

are three different modes:
|
||||
|
||||
- PROCINFO_DECL is defined. This means we are only interested in
|
||||
declarations.
|
||||
|
||||
- PROCINFO_DECL is not defined:
|
||||
|
||||
+ if SHARED is defined the file is included in an array
|
||||
initializer. The .element = { ... } syntax is needed.
|
||||
|
||||
+ if SHARED is not defined a normal array initialization is
|
||||
needed.
