While ARMv8.0 isn’t officially supported in the HPC SDK it’s used by a lot of machines including Raspberry Pis, Jetson Nanos… which are not compatible with ARMv8.1-A.
However, when trying to build targeting ARMv8.0-A from a newer machine (so that -tp=host isn’t an option, we see that such an option is not available, with only Neoverse-N1 and V1 being the options provided:
$ nvc -tp=cortex-a57 hello.c nvc-Error-Switch -tp with unknown keyword cortex-a57 -tp=host|native|neoverse-n1|neoverse-v1 Select target processor host Link native version of HPC SDK cpu math library native Alias for -tp host neoverse-n1 Arm Neoverse N1 architecture neoverse-v1 Arm Neoverse V1 architecture (SVE x 256)
Could a cortex-a57/cortex-a72 target (either is fine, both implement the same ISA level) be made available for those systems for the -tp= option?
While at it, a supported -tp flag for Carmel too (Tegra Xavier) could be quite useful.
