Clemens Backes e62a7f7697 Reland "[wasm][debug] Fix tier down for multiple isolates" ... This is a reland of 902f48bdda, fixed to avoid lock inversion problems detected by TSan. Original change's description: > [wasm][debug] Fix tier down for multiple isolates > > If multiple isolates are using the same module, we need to keep it > tiered down as long as any isolate still has a debugger open. > Also, we cannot short-cut the {NativeModule::TierDown} method, since the > previously triggered tier down might not have finished yet. > For now, each isolate starts an independent tier down (i.e. a full > recompilation). We could optimize this later by skipping functions that > are already tiered down, or are already scheduled for tier down, but we > still need to wait for tier-down to finish on each isolate. > > R=thibaudm@chromium.org > > Bug: v8:10359 > Change-Id: I7ea6a6f5d3977e48718ac5bc94f9831541f6173f > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2190758 > Commit-Queue: Clemens Backes <clemensb@chromium.org> > Reviewed-by: Thibaud Michaud <thibaudm@chromium.org> > Cr-Commit-Position: refs/heads/master@{#67716} Bug: v8:10359 Cq-Include-Trybots: luci.v8.try:v8_linux64_tsan_rel Cq-Include-Trybots: luci.v8.try:v8_linux64_tsan_isolates_rel_ng Change-Id: Ie98cf073fc79e5c6991df6d4466de7b560274070 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2194451 Commit-Queue: Clemens Backes <clemensb@chromium.org> Reviewed-by: Thibaud Michaud <thibaudm@chromium.org> Cr-Commit-Position: refs/heads/master@{#67754}		2020-05-12 15:41:55 +00:00
