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.
