@Zhenhang1213 :
Code looks ok. 
Are all edge cases covered by the lit test now? 

Could you please adjust the commit message to reflect the actual changes?

The updated version looks better. 

I think we need to remove ARMV6T2 from the list, as it does not seem to support 
the feature.

This describes different functionality for mrc p15 c13 than that of ARMV6K, 
ARMV6KZ and later A/R architectures, for example 
https://developer.arm.com/documentation/ddi0333/h/system-control-coprocessor/system-control-processor-registers/c13--thread-and-process-id-registers?lang=en


It seems the current version will select tpidruro mode for -mtp=auto for any 
architecture that supports it. 
Note that this does not seem to be the gcc behaviour, as gcc will only set it 
for armv6k automatically, and for nothing else. 
https://github.com/gcc-mirror/gcc/blob/fdf846fdddcc0467b9f025757f081c5d54319d08/gcc/config/arm/arm.cc#L3972-L3978
This seems a defect in gcc, rather than something to emulate.

I've edited my suggestion a bit to include all architectures known to support 
hardware thread pointer. 
These are: 
Any where version is 7 and above, excluding any MProfile
Version 6 for only ARMV6T2, ARMv6K and ARMv6KZ

@Zhenhang1213 Might I suggest changes along the lines of 

https://github.com/VladiKrapp-Arm/llvm-project/commit/63e4f10eaefc024e2afc41e5151411a383226a8b

This separates the check for whether the platform allows hardware tls from 
whether it is possible to encode using thumb2. Both these checks should be made 
for auto mode, so we don't automatically select this mode for the user when 
they might have some functions compiled with soft mode. 
@smithp35 : This still isn't exactly the same as what gcc does, because there 
auto mode is enabled if it's armv6k and arm mode. This check could be done here 
as well, but could still cause problems if user compiles as in your example 
with __attribute__((target("thumb"))).

The check here is incorrect, if nothing else, the check should be 
'!isMProfile(Tripple)', as no M Profile chips support HardTP. 


Something along the lines of
```
  int Ver = getARMSubArchVersionNumber(Triple);
  llvm::ARM::ArchKind AK = llvm::ARM::parseArch(Triple.getArchName());
  return Triple.isARM() || AK == llvm::ARM::ArchKind::ARMV6T2 ||
 (Ver >= 7 && !isARMMProfile(Triple));

```
But maybe this should be done in the original isHardTPSupported?
