================
Comment at: llvm/include/llvm/ProfileData/SampleProf.h:492
- operator StringRef() const { return FullContext; }
+ operator SampleContextFrames() const { return FullContext; }
bool hasAttribute(ContextAttributeMask A) { return Attributes & (uint32_t)A; }
----------------
The implicit operator here seems unnecessary given you have `getContextFrames` below providing the same thing. Is this needed?
================
Comment at: llvm/include/llvm/ProfileData/SampleProf.h:547
+
+ bool operator!=(const SampleContext &That) const { return !(*this == That); }
+
----------------
The == and != operators are not always opposites. If another instance of this object has the same State/Name/FullContext == and != will both evaluate as true. Should != check on all of these fields/be a direct negation of ==?
