the patent. --HG-- extra : convert_revision : 6fcf5dee440288d8bf92f6c5c2f97ef019975536

2007-09-04X86: Make the movfp microop use FloatRegBits instead of FloatRegs.Gabe Black
This fixes a problem where interpreting arbitrary bits as floating point would change what the value was. These values are legitimate because the fp registers could be used to move around arbitrary data. --HG-- extra : convert_revision : f1d7159ba137702b5722cc7c1b64ed7dd06c21de

2007-08-31X86: Major rework of how regop microops are generated.Gabe Black
The new implementation uses metaclass, and gives a lot more precise control with a lot less verbosity. The flags/no flags reg/imm variants are all handled by the same python class now which supplies a constructor to the right C++ class based on context. --HG-- extra : convert_revision : 712e3ec6de7a5a038da083f79635fd7a687d56e5
