This is a reland of2000aea58aChanges compared to last reland: - Add rule in variants.py for --enable_experimental_regexp_engine. - Make sure --abort-on-contradictory-flags works as well as --fuzzing to disable the checking for fuzzers, including for d8 flags. Original change's description: > Reland^4 "[flags] warn about contradictory flags" > > This is a reland of0ba115e6a9> Changes compared to last reland: > - Fix Python code trying to write to expected_outcomes, which is now a > computed property. > - Fix remaining place in d8.cc that ignored the --fuzzing flag. > - Expect flag contradictions for --cache in code_serializer variant. > > Original change's description: > > Reland^3 "[flags] warn about contradictory flags" > > > > Changes: > > - Also allow second parameter influenced by --cache to be reassigned. > > - Fix --stress-opt to only --always-opt in the last iteration as before. > > > > Original change's description: > > > Reland^2 "[flags] warn about contradictory flags" > > > > > > This is a reland ofd8f8a7e210> > > Change compared to last reland: > > > - Do not check for d8 flag contradictions in the presence of --fuzzing > > > - Allow identical re-declaration of --cache=* > > > > > > Original change's description: > > > > Reland "[flags] warn about contradictory flags" > > > > > > > > This is a reland ofb8f9166664> > > > Difference to previous CL: Additional functionality to specify > > > > incompatible flags based on GN variables and extra-flags, used > > > > to fix the issues that came up on the waterfall. > > > > > > > > This also changes the rules regarding repeated flags: While > > > > explicitly repeated flags are allowed for boolean values as long > > > > as they are identical, repeated flags or explicit flags in the > > > > presence of an active implication are disallowed for non-boolean > > > > flags.
