Reland^2 "[flags] warn about contradictory flags"
This is a reland ofd8f8a7e210Change 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. The latter simplifies specifying conflict rules in > variants.py. Otherwise a rule like > > INCOMPATIBLE_FLAGS_PER_EXTRA_FLAG = { > "--gc-interval=*": ["--gc-interval=*"], > } > > wouldn't work because specifying the same GC interval twice > wouldn't actually count as a conflict. This was an issue with > test/mjsunit/wasm/gc-buffer.js, which specifies > --gc-interval=500 exactly like the extra flag by the stress bot. > > Also, this now expands contradictory flags checking to d8 flags > for consistency. > > Original change's description: > > [flags] warn about contradictory flags > > > > Design Doc: https://docs.google.com/document/d/1lkvu8crkK7Ei39qjkPCFijpNyxWXsOktG9GB-7K34jM/ > > > > Bug: v8:10577 > > Change-Id: Ib9cfdffa401c48c895bf31caed5ee03545beddab > > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2154792 > > Reviewed-by: Clemens Backes <clemensb@chromium.org> > > Reviewed-by: Michael Achenbach <machenbach@chromium.org> > > Reviewed-by: Georg Neis <neis@chromium.org> > > Reviewed-by: Tamer Tas <tmrts@chromium.org> > > Commit-Queue: Tobias Tebbi <tebbi@chromium.org> > > Cr-Commit-Position: refs/heads/master@{#68168} > > Bug: v8:10577 > Change-Id: I268e590ee18a535b13dee14eeb15ddd0a9ee8341 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2235115 > Commit-Queue: Tobias Tebbi <tebbi@chromium.org> > Reviewed-by: Tamer Tas <tmrts@chromium.org> > Reviewed-by: Clemens Backes <clemensb@chromium.org> > Reviewed-by: Georg Neis <neis@chromium.org> > Cr-Commit-Position: refs/heads/master@{#68989} Bug: v8:10577 Change-Id: I31d2794d4f9ff630f3444210100c64d67d881276 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2339464 Commit-Queue: Tobias Tebbi <tebbi@chromium.org> Reviewed-by: Clemens Backes <clemensb@chromium.org> Cr-Commit-Position: refs/heads/master@{#69339}
