bfd/elfnn-aarch64.c: Fix miscalculation of GOTPLT offset for ifunc syms.
The .got.plt header size was not being correctly taken into account
when calculating the offset for relocations against ifunc symbols.
bfd/ChangeLog:
2013-11-26 Will Newton <will.newton@linaro.org>
* elfnn-aarch64.c (elfNN_aarch64_final_link_relocate): Ensure
PLT_INDEX is calculated using correct header size.
ld/testsuite/ChangeLog:
2013-11-26 Will Newton <will.newton@linaro.org>
* ld-aarch64/aarch64-elf.exp: Add ifunc-21 test.
* ld-aarch64/ifunc-21.d: New file.
* ld-aarch64/ifunc-21.s: Likewise.
