Does the testsuite not support parallel build? The testsuite does support parallel execution. However, to enable parallel execution you must use the `THREADS` variable.
For instance, {{{ make test THREADS=9 }}} For details see wiki:Building/RunningTests/Running.
It used to work without issue in previous versions, such 8.4.4.
I'll admit I'm a bit skeptical; GHC's testsuite driver has never supported parallel execution using `make -j` as far as I know. Perhaps it didn't break as violently, but it certainly never worked. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16153#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Without parallel build, the testsuite still fails:
Indeed `ghci063` is a known issue. See #16201. As far as the others are concerned: `T12752` is odd but smells of a broken toolchain (CPP is expected to throw an error on this test due to `-Wcpp- undef`). The rest are performance tests which indeed may vary from machine to machine (see #12758 which improves this situation in `master`). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16153#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Given that it's not the case any more, I am removing the testsuite entirely from the Homebrew build and test process. We'll just hope that the checks performed during your QC cycles on macOS are sufficient. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16153#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
