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.
