== Progress ==

* Zero/sign extension elimination with widening types (TCWG-546 - 9/10) - Fixed ICEs and now can build the cross compiler and do the regression testing with qemu - some test-cases are failing due to condition that rely on overflow; this need fixing. - Bootstrapping on AArch64 still fails (but much later than previously). - Verified CRC is optimized * Improve block memory operations by GCC (TCWG-142 - 1/10) - Looked at the changes since the card was drafted

== Plan ==

* Continue with Zero/sign extension pass.
