cpu/or1k: Define unordered comparisons
Add support for new floating point unordered comparisons. These have been defined in OpenRISC architecture proposal 7[0] and are now included in the architecture specification 1.3. These new instructions provide the ability for floating point comparisons to detect NaNs. [0] https://openrisc.io/proposals/lfsf cpu/ChangeLog: yyyy-mm-dd Stafford Horne <shorne@gmail.com> * or1korfpx.cpu (insn-opcode-float-regreg): Add SFUEQ_S, SFUNE_S, SFUGT_S, SFUGE_S, SFULT_S, SFULE_S, SFUN_S, SFUEQ_D, SFUNE_D, SFUGT_D, SFUGE_D, SFULT_D, SFULE_D, SFUN_D opcodes. (float-setflag-insn-base): New pmacro based on float-setflag-insn. (float-setflag-symantics, float-setflag-unordered-cmp-symantics, float-setflag-unordered-symantics): New pmacro for instruction symantics. (float-setflag-insn): Update to use float-setflag-insn-base. (float-setflag-unordered-insn): New pmacro for generating instructions.
