decgen

V1.41b (15/4/2017): decgen.zip (553,270 bytes). Includes source and binaries for RISC OS (3.5+), Linux and Windows.

A tool for generating instruction set decoders based around user-provided 'encoding' files and 'action' files. Includes example encodings covering the majority of the ARM instruction sets and architectures.

Changes in this version

• Fixed bug in regular code generator that would result in the wrong paths being taken for many trees
• Improved action handling so that identical actions will be merged together
• Tweaked code output so that nodes which only have one reference will be marked as inline functions, to help with compilers that aren't very good at automatic inlining
• RISC OS binary now ARMv8 compatible
