Hi Jakub,

Of course it makes me wonder to what extent we actually do support the
OpenMP 5.1 target_device device_num trait with constant or non-constant
device num:
Answer: If one removes some early errors such that the compiler
continues a bit further, one gets:
36 | !$omp declare variant(variant4)
match(target_device={device_num(0)}) ! OK

sorry, unimplemented: 'target_device' selector set is not supported yet
Hence: Not yet supported, but the Sandra added the basic parsing
support for it to GCC 14 when she improved the handling.
However, the review-pending metadirective patch set
https://gcc.gnu.org/pipermail/gcc-patches/2024-January/642005.html
has
[PATCH 3/8] libgomp: runtime support for target_device selector
Thus, once we GCC 15 development work has started, we can look into
this feature and some other patches ...
