== Progress ==

* Zero/sign extension elimination with widening types (TCWG-546 - 10/10) - Re-wrote the pass from the results of experiments so far - Fixed most of the regression failures - 5 tests are still failing from C/C++/Fortran regression suite.

== Plan ==

* Continue with Zero/sign extension pass. - Get bootstrapping for ARM and AArch64 working - Fix remaining regression failures - Add detail dumps - Remove unnecessary copies (it is now being removed dead code elimination pass) - Get patch ready for upstream discussion
