/**
|
|
* 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.
