Hi,
Recently I used --target=nds32be-elf to configure nds32 gcc,
it seems that the big endian is not set as default.
In the config.gcc, I notice that target_cpu_default is defined as:
nds32le-*-*)
target_cpu_default="0"
nds32be-*-*)
target_cpu_default="0|MASK_BIG_ENDIAN"
But the TARGET_CPU_DEFAULT is not added into TARGET_DEFAULT_TARGET_FLAGS so that
MASK_BIG_ENDIAN is not enabled for nds32be-elf.
The following is the patch to fix this issue. Tested on nds32be-elf.
OK to apply?
