Need Intel oneAPI (LLVM) compiler testing. #89

Closed theurich closed 1 year ago

theurich commented 1 year ago

Intel compilers under oneAPI are different than previous versions of the Intel compilers. The oneAPI compilers are now based on LLVM (btw also the basis for Clang). The new front-ends are called icx, ifx. Intel still offers the "classic" front-ends (ifort, icpc, icc) in the current compiler installations, but the future of Intel compilers is LLVM based.

There have been reports of issues building ESMF with the LLVM based Intel compilers. We need to start testing with them as soon as possible.

Added testing for all three modes of new Intel compilers:

default (ifort+icpx+icx),
classic (ifort+icpc+icc),
oneAPI (ifx+icpx+icx)

to the Gaea C5 Intel compiler combo. All working as expected.
