Re: Creating a wrapper around a function at compile time

Awesome! Thanks! Let's go a little bit into the transformation mechanics itself. I am somewhat familiar with LTO but I am always confused about the transformations scheduled during WPA. Let's assume that: 1. we have the profiling pass, which profiles each argument in each callsite. 2. we are now

Re: Proposal: allow to extend C++ template argument deduction via plugins

Hi Ben, Thanks for your feedback. The original problem I was trying to solve is to do such deduction in my own project where I use self-written wrapper around libpq, so naturally I'm not concerned if I'll be writing in pure C++ or C++ dialect. Actually, I tried to come up with a solution which m
