Hi All, I'm new to ISPC and have been playing around with it a bit to evaluate if it's a possible solution for our codebase. So far I'm liking it ;)
A general question I've not been able to find a solution too is if there is something similar to __builtin_unreachable() in GCC. Looking at this simple example https://ispc.godbolt.org/z/Meee-G I'd like to disable the code path where (S>25) is false for all instances in a gang to get rid of the additional check in the assembly. Keep in mind that this is a simple example so it's not so much about if this will really increase performance, but more about if I can do it. I was hoping for something like: if ( none ( S > 25 ) ) flag_unreachable; Cheers, Christoph -- You received this message because you are subscribed to the Google Groups "Intel SPMD Program Compiler Users" group.
