New Revision: 97276
URL: http://llvm.org/viewvc/llvm-project?rev=97276&view=rev
Log:
Added the follwoing 32-bit Thumb instructions for disassembly only:
o Parallel addition and subtraction, signed/unsigned
o Miscellaneous operations: QADD, QDADD, QSUB, QDSUB
o Unsigned sum of absolute differences [and accumulate]: USAD8, USADA8
o Signed/Unsigned saturate: SSAT, SSAT16, USAT, USAT16
o Signed multiply accumulate long (halfwords): SMLAL<x><y>
o Signed multiply accumulate/subtract [long] (dual): SMLAD[x], SMLALD[X], SMLSD[X], SMLSLD[X]
o Signed dual multiply add/subtract [long]: SMUAD[X], SMUSD[X]
