I think there are several common use cases for these attributes -
1. to mark what ISA a function is compiled for: (i.e. is it a
thumb16/thumb32/ARM?)
2. to constrain the generated code to use specific co-processors.
At least for case 2, the ARMTargetMachine/ARMSubtarget contains a
distinct set of flags which should be output in the file scope section
of the attributes
For case 1, I don't know how common it is for the same executable t...

Hi Duncan,
I assumed you knew what build attributes were in the first place, my mistake.
For a full explanation of what they are, see ARM ABI Addenda, section
2.1 (PDF). (Google's first hit for

no, I mean
