* [CUDA] Emit deferred diagnostics during Sema rather than during codegen.Justin Lebar2016-10-131-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Emitting deferred diagnostics during codegen was a hack. It did work, but usability was poor, both for us as compiler devs and for users. We don't codegen if there are any sema errors, so for users this meant that they wouldn't see deferred errors if there were any non-deferred errors. For devs, this meant that we had to carefully split up our tests so that when we tested deferred errors, we didn't emit any non-deferred errors. This change moves checking for deferred errors into Sema. See the big comment in SemaCUDA.cpp for an overview of the idea. This checking adds overhead to compilation, because we have to maintain a partial call graph. As a result, this change makes deferred errors a CUDA-only concept (whereas before they were a general concept). If anyone else wants to use this framework for something other than CUDA, we can generalize at that time. This patch makes the minimal set of test changes -- after this lands, I'll go back through and do a cleanup of the tests that we no longer have to split up.

* [CUDA] Print a "previous-decl" note when calling an illegal member fn.Justin Lebar2016-08-101-3/+3
| | | | | | | | | | | | | | | Summary: When we emit err_ref_bad_target, we should emit a "'method' declared here" note. We already do so in most places, just not in BuildCallToMemberFunction.

* [CUDA] Remove three obsolete CUDA cc1 flags.Justin Lebar2016-03-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: * -fcuda-target-overloads Previously unconditionally set to true by the driver. Necessary for correct functioning of the compiler -- our CUDA headers wrapper won't compile without this. * -fcuda-disable-target-call-checks Previously unconditionally set to true by the driver. Necessary to compile almost any external CUDA code -- almost all libraries assume that host+device code can call host or device functions. * -fcuda-allow-host-calls-from-host-device No effect when target overloading is enabled.
