Mordante marked 2 inline comments as done. Mordante added a comment. Further testing revealed the Codegen already has decided the limit. `clang/lib/CodeGen/CGRecordLayout.h:64`:
struct CGBitFieldInfo { /// The offset within a contiguous run of bitfields that are represented as /// a single "field" within the LLVM struct type. This offset is in bits. unsigned Offset : 16; /// The total size of the bit-field, in bits. unsigned Size : 15; So I'll look at using that limit. I also want to look at improving the diagnostics a bit more. ================ Comment at: clang/include/clang/Basic/DiagnosticSemaKinds.td:5186-5189 +def warn_bitfield_width_exceeds_maximum_width: Error< + "width of bit-field %0 doesn't fit in a 64 bit unsigned integer">; +def warn_anon_bitfield_width_exceeds_maximum_width : Error< + "width of anonymous bit-field doesn't fit in a 64 bit unsigned integer">; ---------------- aaron.ballman wrote: > rsmith wrote: > > aaron.ballman wrote: > > > I feel like this situation should be an error rather than a warning -- > > > what could the code possibly have meant? > > The name of the diagnostic and the kind of diagnostic should agree. > > Currently we have `warn_` vs `Error<`. > Ooof, good catch!

It is a copy paste bug and I forgot to change the `warn_` prefix to `err_`.
