Well... if you write the test that way, then this is pretty much the only way to avoid random optimizer changes from braking the test. But it has the opposite problem -- it's so strict that random changes to lldb (and its output) can break it. And since the test will only run on x86 windows, most lldb contributors (everyone except you, basically) will only notice it after it breaks. This isn't how we usually write tests (although one could make a case doing more of it -- our coverage of debugging optimized code is fairly low). Can you say (in english) what are the properties that you are trying to check there? Maybe we can find a better way to do that... ================ Comment at: lldb/source/Plugins/SymbolFile/NativePDB/PdbAstBuilder.cpp:1153 + StringIdRecord sir; + cantFail( + TypeDeserializer::deserializeAs<StringIdRecord>(parent_cvt, sir)); ---------------- rnk wrote: > We shouldn't use cantFail if it isn't implied by local invariants.

(FWIW, the amount of cantFails in the PDB code definitely makes me uncomfortable, but I don't know enough about PDBs or the PDB reader to say which of those are good invariants. But in general, we treat debug info as "user input" and try to avoid crashing on malformed data.) ================ Comment at: lldb/test/Shell/SymbolFile/NativePDB/inline_sites_live.test:2 +# clang-format off +# REQUIRES: lld, system-windows + ---------------- you also need `REQUIRES: native && target-x86_64` Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D121967/new/ https://reviews.llvm.org/D121967 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
