Hi, I just downloaded VS2017 RC on a clean Win10 machine, checked out LLVM & clang and tried to build clang.
The following code in
\tools\clang\utils\TableGen\ClangDiagnosticsEmitter.cpp failed to compile:
RecordSet DiagsInPedanticSet;
RecordSet GroupsInPedanticSet;
InferPedantic inferPedantic(DGParentMap, Diags, DiagGroups,
DiagsInGroup);
inferPedantic.compute(&DiagsInPedanticSet, &GroupsInPedanticSet);
auto &PedDiags = DiagsInGroup["pedantic"];
// Put the diagnostics into a deterministic order.
RecordVec DiagsInPedantic(DiagsInPedanticSet.begin(),
DiagsInPedanticSet.end());
because the RecordSet iterators created by DiagsInPedanticSet.begin() and
DiagsInPedanticSet.end() are not const iterators and the VS2017 vector code
tries to use (binary) operator* with one of these iterators, and expects to
get a const ValueT but the compiler can currently only resolve the non-const
operator* on the DenseSet iterator. The patch implements operator* and
operator-> for const ValueT on the iterators in include/llvm/ADT/DenseSet.h.
The attached patch resolves the VS2017 build failure for me - do I need to
run further checks before someone can review/commit it for me?
Note: the fix is in the LLVM repository, not the clang repository.
Thanks, Andrew R
