Unknown register ymm0h requested >From what I can tell from furious googling is that the ymm registers have = changed location from broadwell-e to skylake-x. I can see references to the ymm registers in gdb's codebase, with apparent = positioning related to features like org.gnu.gdb.i386.avx & org.gnu.gdb.i38= 6.avx512. Being a complete novice around gdb's codebase, I'm not sure if I need to en= able or state something at configure stage so that the right ymm register l= ocation is referenced. gdb server 8 in ubuntu bionics repos works OK on the skylake-x platform, bu= t when I compile myself it does not. Is there something specific I need to be stating at compile time to "get" g= dbserver 8 to work on skylake-x Paul
