 Changes to the PowerPC Target
 -----------------------------
 
- During this release ...
+Optimization:
+
+  *  Improved register pressure estimates in the loop vectorizer based on type
+  *  Improved the PowerPC cost model for the vectorizer
+  *  Enabled vectorization of math routines on PowerPC using MASSV (Mathematical Acceleration SubSystem) library
+
+compiler-rt:
+
+  *  Added/improved conversion functions from IBM long double to 128-bit integers
+
+Codegen:
+
+   *  Optimized memory access instructions in loops (pertaining to update-form instructions and address computation)
+   *  Added options to disable hoisting instructions to hotter blocks based on statically or profile-based block hotness estimates
+   *  Code generation improvements (particularly with floating point and vector code as well as handling condition registers)
+   *  Various infrastructural improvements, code refactoring, and bug fixes
+   *  Optimized handling of control flow based on multiple comparison of same values
+
+Tools:
+
+  *   llvm-readobj supports displaying file header, section headers, symbol table and relocation entries for XCOFF object files
+  *   llvm-objdump supports disassembling physical sections for XCOFF object files
