I am very interested in seeing a qualification plan for ARM given that it is
a widely used target with several combinations of options/modes to be
tested. I & my team use ARM hardware for running tests and we run all LLVM
test suite tests as part of qualification process. I had started a similar
conversation in llvm-commits, but this is probably the right forum. It will
save everyone a lot of time if we can all agree on qualification tests and
options for ARM and would be happy to initiate the discussion and process
for this.
