commit a75cf613fd7d0a48d526a996ff5c250c599d3ab7
Author: Ed Schouten <ed@nuxi.nl>
Date: Thu Oct 29 13:49:03 2015 +0000
Add support for AArch64 CloudABI binaries.
ld * Makefile.am (ALL_64_EMULATION_SOURCES): Add support for
CloudABI on aarch64. For this target we have to make sure we use
ELFOSABI_CLOUDABI instead of ELFOSABI_NONE.
* configure.tgt (targ_emul): Likewise.
* emulparams/aarch64cloudabi.sh: New file.
* emulparams/aarch64cloudabib.sh: New file.
* Makefile.in: Regenerate.
bfd * config.bfd (targ_defvec): Add support for CloudABI on aarch64.
For this target we have to make sure we use ELFOSABI_CLOUDABI
instead of ELFOSABI_NONE.
* configure.ac (tb): Likewise.
* elfnn-aarch64.c: Likewise.
* targets.c (_bfd_target_vector): Likewise.
* configure: Regenerate.
gas * config/tc-aarch64.c (elf64_aarch64_target_format): Select the
cloudabi format if the TARGET_OS is cloudabi.
