That was a long time ago. :) > Does anyone know what happened to the patch? I think it may have died due to lack of interest. I'm not aware many folks like you that have actually been using it. At the time, I obtained a FSF copyright assignment for the code at the request of one of the binutils maintainers. AFAIK the patch was never incorporated although I do not remember seeing any technical concerns from the binutils maintainers before I moved on to a different project. > Is there another tool that provides the same information? Not that I'm aware of. The binutils patch was based on an earlier stand-alone utility that processed `objdump -d` output but that program lacked Itanium 2 support and several other improvements that I put in the binutils version. I can't remember very much about the code but I suspect that some of these changes would not have been adaptable to the stand-alone utility. > > I've found the tool very useful for providing insight into IA64 > code scheduling. Thanks. We thought it might be useful to someone. Gary -- Gary Hade IBM Linux Technology Center 503-578-4503 IBM T/L: 775-4503 garyhade@us.ibm.com http://www.ibm.com/linux/ltc
