Subject: [PATCH] ia64: Update elf_machine_load_address for static PIE
Date: Fri, 29 Sep 2017 21:35:00 -0000 [thread overview]
Message-ID: <20170929213538.GQ2482@gmail.com> (raw)
ia64 uses a local label to compute load address, which works with static
PIE. We just need to return 0 if _DYNAMIC is undefined for static
executable.
OK for master?
* sysdeps/ia64/dl-machine.h (elf_machine_dynamic): Return 0 if
_DYNAMIC is undefined for static executable.
