/* This information must be kept in sync with the _DL_HWCAP_COUNT and | ||
_DL_PLATFORM_COUNT definitions in procinfo.h. | ||
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. | ||
