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 | |
fda19e04 L |
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. | |
