That is indeed the sort of horror we used to implement out DontOptimise(something.cpp) and DontOptimiseMuch(somethingelse.cpp) macros at a now-famously-defunct investment bank. The code outlived the bank... B^> Rgds Damon On 29 May 2012, at 18:12, Kelly O'Hair wrote: > > You should be abl

Hi, FWIW, and I have not looked at any of the build system for this, when building large optimised cross-platform critical C++ projects I had the option to turn down or off optimisation for individual files for individual compilers/platforms. At worst you might accomplish that (with other main
