Remove the `nosync` attribute from the memory intrinsic definitions (i.e. memset, memcpy, memmove). Like native memory accesses, memory intrinsics can be volatile. This is indicated by an immarg in the intrinsic call. All else equal, a volatile memory intrinsic is `sync`, so we cannot annotate the intrinsic functions themselves as `nosync`. The attributor and function-attr passes know to take the volatile bit into account. Since `nosync` is a default attribute, this means we have to stop using the DefaultAttrIntrinsic tablegen class for memory intrinsics, and specify all default attributes other than `nosync` explicitly. Most of the test changes are trivial churn, but one test case (in nosync.ll) was in fact incorrect before this change. Differential Revision: https://reviews.llvm.org/D102295 |
