| /** |
| * 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. |
