Changes to the MIPS Target
- During this release ...
+* The microMIPS64R6 backend is deprecated and will be removed in the next
+* The MIPS backend now directly supports vector types for arguments and return
+ values (previously this required ABI specific LLVM IR).
+* Added documentation for how the MIPS backend handles address lowering.
+* Added a GCC compatible option -m(no-)madd4 to control the generation of four
+ operand multiply addition/subtraction instructions.
+* Added basic support for the XRay instrumentation system.
+* Added support for more assembly aliases and macros.
+* Added support for the ``micromips`` and ``nomicromips`` function attributes
+ which control micromips code generation on a per function basis.
+* Added the ``long-calls`` feature for non-pic environments. This feature is
+ used where the callee is out of range of the caller using a standard call
+ sequence. It must be enabled specifically.
+* Added support for performing microMIPS code generation via function
+* Added experimental support for the static relocation model for the N64 ABI.
+* Added partial support for the MT ASE.
+* Added basic support for code size reduction for microMIPS.
+* Fixed numerous bugs including: multi-precision arithmetic support, various
+ vectorization bugs, debug information for thread local variables, debug
+ sections lacking the correct flags, crashing when disassembling sections
+ whose size is not a multiple of two or four.
