Hi,
this patch series implements the re-work of the OpenACC "kernels"
implementation that has been announced at the GNU Tools Track of this
year's Linux Plumbers Conference; see

of the patches have also been committed to the devel

Hi!
While replacing the built-in machinery, we agreed to defer some necessary
refactoring of the overload processing. This patch cleans it up considerably.
I've put in one FIXME for an additional level of cleanup that should be done
independently. The various helper functions (resolve_VEC_*) ca
Hi Petter.
I believe you have forgotten the line `global:` in the file
`gcc/jit/libgccjit.map`.
I'm not sure what this line does, but it is there for all other ABI.
David: What do you think?
Regards.

Hi,
Add support for ptx isa version 7.0, required for the addition of -misa=sm_75
and -misa=sm_80.
Tested by setting the default ptx isa version to 7.0, and doing a build and
libgomp test run.
Committed to trunk.
Thanks,
- Tom

The patch fixes a few ASAN errors (global variable access out of bounds).
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
