The fucomi* opcodes were only introduced for the Pentium Pro. They do not exist for an MMX Pentium. Use the fucom* instructions instead and move the condition codes from the fp flags register to the integer flags register explicitly. The use of fucomi* opcodes in ggen.go was introduced in 1.5 (CL 8738). The bad ops were generated for 64-bit floating-point comparisons. The use of fucomi* opcodes in gsubr.go dates back to at least 1.1. The bad ops were generated for float{32,64} to uint64 conversions.
