Thanks.
The following is the result from godbolt (except the beta releases of 21.1.*)
version __INTEL_COMPILER __INTEL_COMPILER_UPDATE 13.0.1 1300 (unsupported) 16.0.3 1600 3 17.0.0 1700 0 18.0.0 1800 0 19.0.0 1900 0 19.0.1 1900 0
Presumably, the version string xx.yy.zz corresponds to __INTEL_COMPILER=xxyy __INTEL_COMPILER_UPDATE=zz
The output from 19.0.1 does not make sense, though.
BTW, when I tried ICC a few years ago, I could not build the kernel with it.
