TTA-based Co-Design Environment (TCE) v1.20 released

TTA-based Co-Design Environment (TCE) is an open application-specific
instruction-set processor (ASIP) toolset for design and programming of
customized co-processors (typically programmable accelerators). It is
based on the energy efficient Transport Triggered Architecture (TTA)
processor template.

The toolset provides a complete retargetable co-design flow from high-
level language programs down to FPGA/ASIC synthesizable processor RTL
(VHDL and Verilog generation supported) and parallel program binaries.

Processor customization points include the register files, function
units, supported operations, and the interconnection network.

This release adds support for LLVM 9, modifies predicate evaluation to
look only at the lowest bit, adds constant shift amount operations among
other improvements and fixes.
