4d13cb0a8a
This patch modifies hasStandardEncoding() / inMicroMipsMode() / inMips16Mode() methods of the MipsSubtarget class so only one can be true at any one time. That prevents the selection of microMIPS and MIPS instructions and patterns that are defined in TableGen files at the same time. A few new patterns and instruction definitions hae been added to keep test cases passed. Differential revision: https://reviews.llvm.org/D51483 llvm-svn: 341338
