I took local variables from rust_gen_target function for arm and aarch64
targets. Refer below, the tspec varibles for 'arm' generated with NoneType.
Locals at rust_gen_target for arm::
arch = arm
rust_arch = arm
arch_abi = arm
*tspec['data-layout'] = None*
*Type of tspec['data-layout'] = <class 'NoneType'>*
tspec['data-layout'] = None
Type of tspec['data-layout'] = <class 'NoneType'>
DEBUG: Python function do_rust_gen_targets finished
Locals at rust_gen_target for aarch64::
arch = aarch64
rust_arch = aarch64
arch_abi = aarch64
*tspec['data-layout'] = aarch64-unknown-linux-gnu*
*Type of tspec['data-layout'] = <class 'str'>*
tspec['data-layout'] = e-m:e-i8:8:32-i16:16:32-i64:64-i128:128-n32:64-S128
Type of tspec['data-layout'] = <class 'str'>
tspec['max-atomic-width'] = 128
Type of tspec['max-atomic-width'] = <class 'int'>
tspec['target-pointer-width'] = 64
Type of tspec['target-pointer-width'] = <class 'str'>
tspec['target-c-int-width'] = 32
Type of tspec['target-c-int-width'] = <class 'str'>
tspec['target-endian'] = little
Type of tspec['target-endian'] = <class 'str'>
tspec['arch'] = aarch64
Type of tspec['arch'] = <class 'str'>
Reason for changing arm-eabi to arm:
I noticed that the previous change introduced this bug, so I reverted the
arm-eabi to arm and the issue is fixed.
