bfd/elfnn-aarch64.c: Fix calculation of DT_RELASZ
The current code subtracts the size of the output section containing relplt from RELASZ. In some cases this will be the same output section as the dynamic relocs causing a value of zero to be output. Calculating the size from input sections seems to make more sense. bfd/ChangeLog: 2014-03-25 Will Newton <will.newton@linaro.org> * elfnn-aarch64.c (elfNN_aarch64_finish_dynamic_sections): Set value of DT_PLTRELSZ and DT_RELASZ based on the size of input sections rather than output sections. ld/testsuite/ChangeLog: 2014-03-25 Will Newton <will.newton@linaro.org> * ld-aarch64/aarch64-elf.exp: Add relasz dump test. * ld-aarch64/relasz.d: New file. * ld-aarch64/relasz.s: Likewise.
