[llvm-commits] [PATCH] Correctly fail decoding of LDRD with odd Rt field

[James Molloy]

Hi,

 

The attached patch causes decoding to fail if the Rt field of an LDRD/STRD
is odd (Rt&0x1 != 0), as specified in A.6.68. Testcase added.

 

I wanted to add an assert to the encoder too, but couldn't see an obvious
way to do this as the Rt field is decoded by the generic
"getMachineOpValue()" function direct from tablegen.

 

Cheers,

 

James
