New Revision: 152817
URL: http://llvm.org/viewvc/llvm-project?rev=152817&view=rev
Log:
Revert r152202: "Use uint16_t to store InstrNameIndices in MCInstrInfo."
We cannot limit the concatenated instruction names to 64K. ARM is
already at 32K, and it is easy to imagine a target with more
instructions.
