Add ILP32 support to gdb.
This patch adds AARCH64:ilp32 support to gdb and sets
up the correct sizes for some types like pointers and long.
Also sets up the correct linker map offsets for Linux.
2016-08-31 Andrew Pinski <apinski@cavium.com>
* aarch64-tdep.h (gdbarch_tdep): Add ilp32 field.
* aarch64-tdep.c (aarch64_gdbarch_init): Setup ILP32 support.
Make sure the gdbarches have compatible ilp32 flags.
Set long and ptr sizes correctly for ilp32.
* aarch64-linux-tdep.c (aarch64_linux_init_abi):
Add support for ILP32.
