Hi Andreas,
I talked with Chris about this the morning, and I think we agreed that
lli based tests for this stuff are ok, as long as we limit them to
just a few. The main thing we basically need lli for is to test the
generation of the profiling information; I think a single solid test
for that would be good enough for now.
We should solve the problem that this requires the JIT, though. A
simple first option is to disable the test if there is no JIT support.
A slightly better one would be to run it using the .bca version of the
profiling information, but that of course requires that the user
configure with llvm-gcc support.
I think we can find ways to test some of the other stuff without using
lli. For example, the static profile provider should be good enough to
test llvm-prof's output.
Sound OK?
- Daniel
