* aarch64: Add support for GNU indirect functions.willnewton2013-10-031-66/+604
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for STT_GNU_IFUNC symbols to the AArch64 bfd backend. The tests are ported from the ld-ifunc tests but are enabled for cross builds so can be run easily without hardware or a simulator. bfd/ChangeLog: 2013-10-03 Will Newton <will.newton@linaro.org> * configure: Regenerate. * configure.in: Build elf-ifunc.o for AArch64. * elfnn-aarch64.c: Include objalloc.h.
