+Changes to the Debug Info
+---------------------------------
+
+* LLVM now supports the debug entry values (DW_OP_entry_value) production for
+ the x86, ARM, and AArch64 targets by default. Other targets can use
+ the utility by using the experimental option ("-debug-entry-values").
+ This is a debug info feature that allows debuggers to recover the value of
+ optimized-out parameters by going up a stack frame and interpreting the values
+ passed to the callee. The feature improves the debugging user experience when
+ debugging optimized code.
