The --dump-spirv option tells tint_unittests to output the SPIR-V assembly text for a module which did not make the SPIR-V reader fail. This lets us get extract a corpus of SPIR-V modules, and lets us more easily verify that the test shaders are valid in the first place. Also: - Add test/extract-spvasm.py to split that output to separate SPIR-V assembly files - Add optional second argument test/test-all.sh to specify a directory look for input files. - BUILD.gn: Add dependency from //test:tint_unittests_main to //test:tint_unittests_config to pick up source dependency on the internal header of the SPIRV-Tools optimizer, needed by the indirection through src/reader/spirv/parser_impl_test_helper.h This is useful for bulk testing Fixed: tint:756 Change-Id: I4fe232ac736003f7d9be35544328302d652381ea Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/49605 Auto-Submit: David Neto <dneto@google.com> Commit-Queue: Corentin Wallez <cwallez@chromium.org> Kokoro: Kokoro <noreply+kokoro@google.com> Reviewed-by: Corentin Wallez <cwallez@chromium.org> Reviewed-by: Ben Clayton <bclayton@google.com>
