 | |
|  * These two symbols are declared in a C file so that the linker
 | |
|  * uses R_ARM_RELATIVE relocation, rather than the R_ARM_ABS32 one
 | |
|  * it would use if the symbols were defined in the linker file.
 | |
|  * Using only R_ARM_RELATIVE relocation ensures that references to
 | |
|  * the symbols are correct after as well as before relocation.
 | |
|  *
 | |
|  * We need a 0-byte-size type for these symbols, and the compiler
 | |
|  * does not allow defining objects of C type 'void'. Using an empty
 | |
|  * struct is allowed by the compiler, but causes gcc versions 4.4 and
 | |
|  * below to complain about aliasing. Therefore we use the next best
 | |
|  * thing: zero-sized arrays, which are both 0-byte-size and exempt from
 | |
|  * aliasing warnings.
