Re: [Quantlib-dev] Test suite run time

[Peter C. <pca...@gm...>]

Hello,

to give a benchmark, it takes around 8h to run memcheck on the whole
test-suite, which means a slow-down factor of approximately 50x. This is
with -O3 though, which may hide or produce bogus uninitialized value errors
under certain (but rare) circumstances (according to the valgrind
documentation). Since its diagnostics concerning memory errors seems pretty
much exhaustive (it is e.g. comparable to clang's address + memory + leak
sanitizer), I am wondering what Visual Studio is (thinking it is) doing? Is
it turning off optimization maybe? Or is it doing something in the
direction of thread-safety?

Is it possible to switch optimization levels, debug symbol generation and
sanitizing code instrumentation separately from each other in the studio?
If yes, one can maybe find a viable compromise for these settings between
running time and error sensitivity depending on what exactly one is
expecting.

Peter
