| * 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. | |
