Can you handle all features as follows instead of checking a particular option?

handleTargetFeaturesGroup(Args, Features, options::OPT_m_amdgpu_Features_Group)

There is code in AMDGPU tool chain you can use as a reference.

Changed patch to us handleTargetFeatures, to consume all -m options passed into clang.

Can you add some tests? Preferably with -mxnack/-mno-xnack, -msram-ecc/-mno-sram-ecc, -mcode-object-v3/-mno-code-object-v3

I've added a lit test to check for options such as -mxnack/-mno-xnack, -msram-ecc/-mno-sram-ecc, -mcode-object-v3/-mno-code-object-v3

Is it still code object v2 by default?

Yes, but it will need this PR:
So that the default is set.

LGTM. Please make sure to update your commit message as your patch processes all m options now.

I think this breaks the attributes already listed in the functions on the IR since -mattr overrides those. I think we need to stop using subtarget features to communicate this

I reverted this in rC353893 because it was still causing test failures.

This was submitted again with the fix. Thanks!
