/* This information must be kept in sync with the _DL_HWCAP_COUNT,
HWCAP_PLATFORMS_START and HWCAP_PLATFORMS_COUNT definitions in
dl-hwcap.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.
