[PATCH] [ARM] Adding missing Tag_DIV_use test for the Cortex-M7

[Charlie Turner]

The v7-M cores have SDIV and UDIV required in Thumb mode.

The correct value for Tag_DIV_use is therefore 0 for these cores (i.e.,
don't emit it)

 

I missed the Cortex-M7 CPU in a previous patch which attempted to implement
full coverage of the existing CPUs / architecture tested in
tests/CodeGen/ARM/build-attributes.ll

 

Please find patch attached.

 

Kind regards,

Charlie.
