Reland "[wasm][inspector][test] Add more tests for code offsets" This is a reland of 4719dae1a4ab2067120cf0dbab89514adf662b73. The "V8 Linux64 TSAN - stress-incremental-marking" bot adds the --stress-incremental-marking flag for all variants, hence the SKIP in the status file was not triggered. We just explicitly disable the --stress-incremental-marking flag for the two new tests. This works for the "stress_incremental_marking" variant as well as the specific bot. Original change's description: > [wasm][inspector][test] Add more tests for code offsets > > The code offsets are sometimes wrong when compiled with streaming > compilation. Thus add more tests for synchronous, asynchronous, and > streaming compilation. The reported code offsets should all match. This > will be fixed in a follow-up CL. > > In order to make asynchronous WebAssembly compilation finish, the > inspector-test executable needs to pump the message loop before waiting > for new tasks to come in, just as other executables like d8. > This is added in this CL, but because of another bug this is skipped in > the stress-incremental-marking variant. Hence the new tests are also > skipped there. > > R=szuend@chromium.org > CC=ahaas@chromium.org > > Bug: chromium:1150303, v8:10748 > Change-Id: Ie1d63c8d6795e61627d838b7fa7b21e6728befc0 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2562382 > Reviewed-by: Andreas Haas <ahaas@chromium.org> > Commit-Queue: Clemens Backes <clemensb@chromium.org> > Cr-Commit-Position: refs/heads/master@{#71483} Bug: chromium:1150303 Bug: v8:10748 Change-Id: I9adb9fc0250fab5c43dc85b695f4d338a9c7183c Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2565128 Reviewed-by: Andreas Haas <ahaas@chromium.org> Commit-Queue: Clemens Backes <clemensb@chromium.org> Cr-Commit-Position: refs/heads/master@{#71492}
