In GHA, we build
codegen_funcandcodegen_shared_objwithout sanitisers to generate machine code for test runs. Currently, we do it once for every test run in the matrix. This PR changes the behaviour to build it once per workflow run.Different jobs in the matrix run in parallel, so theoretically this change should not reduce overall runtime as the time we save in
tests(<Sanitiser>)is now spent inconan-cachemakingconan-cache + tests(<Sanitiser>)the same. However, this does reduce considerably the aggregate runtime.Take as an example a run without this fix and a run with this fix .
