From Ira Baxter answer on, Why do the INC and DEC instructions not affect the Carry Flag (CF)?
Mostly, I stay away from
INCandDEC
Depending on the CPU implementation of the instructions, a partial register update may cause a stall. According to Agner Fog's optimization guide, page 62,
For historical reasons, the
INCandDECinstructions leave the carry flag unchanged, while the other arithmetic flags are written to. This causes a false dependence on the previous value of the flags and costs an extra μop. To avoid these problems, it is recommended that you always useADDandSUBinstead ofINCandDEC. For example,INC EAXshould be replaced byADD EAX,1.
