The Intel Classic Compiler had a compilation flag -ax which I'd use to generate additional code paths for multiple instructions sets, such as AVX512, which was very convenient as I'd only build and receive a single binary.
With the next-generation intel compiler the documentation omits this flag from the full list of compiler flags, but still makes reference to it in other sections (including the porting guide). When I attempt to use it with versions 2022.0.0 or 2022.0.1, ICPX tells me the flag is unrecognized:
$ icpx -axCORE-AVX512
icpx: command line warning #10430: Unsupported command line options encountered
These options as listed are not supported.
For more information, use '-qnextgen-diag'.
option list:
-axCORE-AVX512
Is there any way to recover the old behaviour with the new compiler? Otherwise it looks like I will have to quintuple my CI time spent building and deploying to ship 5 binaries instead of one, not to mention that users will also now need to know what instructions their CPU supports.
