Other information

There are a number of tests that are failing due to artifacts of testing. A number of these failed tests need extra flags, which are added in the cmake. Tests for which flags which could not be added are disabled.

collaborative_call_once :-s ALLOW_MEMORY_GROWTH=1 (it was -s TOTAL_MEMORY=128MB)
parallel_invoke: --preload-file /proc/self/status (required only for tests)
task_scheduler_handle: Hardware dependent section sigwait and waitpid fails. – removing them in tests works
task_group :Test_task_group: --preload-file /proc/self/status (required only for tests)
task_group_status: Test_task_group: --preload-file /proc/self/status (required only for tests)
task_handle
Test_task_group, test_task_arena (test that cover this passes): Conditional pass
task_arena
test_task_arena.cpp: Test for task arena entry consistency: FPU control state has not been set correctly
this_task_arena (works)
test_task_arena.cpp: Test for task arena entry consistency: FPU control state has not been set correctly
task_scheduler_observer (works)
test_task_arena.cpp: Test for task arena entry consistency: FPU control state has not been set correctly

We were only interested in the list of APIs that work for emscripten and therefore we have not yet investigated failure of malloc tests. The malloc tests are disabled if they are failing.

Hi @JhaShweta1

We got this PR to ConanCenter, applying this patch to 2021.9.0: conan-io/conan-center-index#17777

I see in the patch you are from intel, it would be great to know if this is something that is expected to eventually land and be merged, if there are any potential risks, it seems that it has been there since January without further reviews. Any hint would be very appreciated, many thanks!

@memsharded Thanks for your interest to this patch. WASM support is work in progress on our side. From the code change you can see, that currently not all TBB tests will be working.
We welcome any feedback and/or contributions to bring it to mergeable quality.
