Why would be crazy to run the test suite on parallel? Because DejaGNU
My compiler's test suite is driven by a poor-man's version of DejaGNU
(also written on Tcl, but not requiring Expect) that supports parallel
runs (with a -j command-line parameter, á la make) and works on Linux
Since long time ago I'm thinking on expanding its functionality for
accepting DejaGNU test cases and add it to the cmake build, but I'm
afraid of corner cases. You know, the 99% of the complexity on the 1% of
Would you consider parallel runs and Windows support enough motivation
for rewriting those (hypothetical) corner cases as equivalent but
