ILP32: BFD
Rebased 2c5e2ba3ced851a18c488c630abd00ca99523bbd from linaro's
gdb-aarch64-ilp32 branch on GDB 8.1-release.
bfd:
2017-03-06 Andrew Pinski <apinski@cavium.com>
Steve Ellcey <sellcey@cavium.com>
* cpu-aarch64.c (compatible):
Don't reject different ILP32/LP64 ABI's here.
* elfnn-aarch64.c (elfNN_aarch64_merge_private_bfd_data):
Add an error message on why endianess is rejected.
Reject different ILP32/LP64 ABI settings.
* elfxx-aarch64.c (_bfd_aarch64_elf_grok_prstatus): Handle
size and offset of ILP32 executables.
(_bfd_aarch64_elf_grok_psinfo): Ditto.
