Now is available version 0.1.1 in my site. New features are:
* support for Windows
* register ranges, symbols with register ranges (you can name registers)
* fixed Gallium and AMD Catalyst binary generator
* fixed clrxasm
* GCN ISA documentation
* many fixes
Support for AMD OpenCL 2.0 kernel binaries will be in next version (0.1.2). The new binary format differs significantly and it requires quite lot of works.
I already integrated this GCN assembler into my tripcode generator, and it works great! Now I can dynamically generate GCN assembler sources at run-time and generate binaries on the fly with this assembler with 10% increase in performance compared to regular OpenCL kernels. I cannot wait for the next version with OpenCL 2.0 support. I am more than happy to help you with testing with two 7990s (GCN 1.0) and two 290Xs (GCN 1.1).
