Go performance updates for Power
I rewrote most of the math/big arithmetic implementations so they perform better on Power. Commit 9459c03, which I already mentioned here before, added new implementations for addVV/subVV with up to ~3x

Advance Toolchain for Linux on Power 10.0-4 released
A new update for the Advance Toolchain for Linux on Power 10.0 is released. Advance Toolchain for Linux on Power 10.0-4 new features GCC provides: Fix for incorrect code generation for __divkf3.
Go: Changed function alignment to 16 bytes for Power
I just added a simple, but important change for Power. In order to eliminate inefficiencies in the iBuffer, all functions are now aligned to 16 bytes. This opens a new
Go: Performance optimization for addVV for Power
I added a new implementation for addVV (math/big package) for Power architecture. The new assembly implementation leverages specific Power instructions and provides a speedup of ~3x over the generic implementation in Go.

Go: Cleanup of legacy code on Big Endian Power architecture
As I mentioned in my previous post, in Go 1.9, the new minimum processor requirement for ppc64 Big Endian will be POWER8. I started cleaning up old code that was
Go: Performance optimization for IndexByte for Power
I added a new implementation for both bytes·IndexByte and strings·IndexByte for Power architecture. The new lazy search-based algorithm gives a speedup of up to 15x over the previous implementation. This
