19/* This information must be kept in sync with the _DL_HWCAP_COUNT,
20 HWCAP_PLATFORMS_START and HWCAP_PLATFORMS_COUNT definitions in
21 dl-hwcap.h.
22
23 If anything should be added here check whether the size of each string
24 is still ok with the given array size.
25
26 All the #ifdefs in the definitions are quite irritating but
27 necessary if we want to avoid duplicating the information. There
28 are three different modes:
29
30 - PROCINFO_DECL is defined. This means we are only interested in
31 declarations.
32
33 - PROCINFO_DECL is not defined:
34
35 + if SHARED is defined the file is included in an array
36 initializer. The .element = { ... } syntax is needed.
37
38 + if SHARED is not defined a normal array initialization is
39 needed.
