https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111020 --- Comment #5 from H. Peter Anvin --- I don't think source code modifications are a huge problem, but at this point they require tracking down each individual bit. As far as trapping implementations are concerned: 1. In deeply embedded implem

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111020 --- Comment #1 from Andrew Pinski --- This sounds more like something which should be designed on at ISA level and since RISC-V is an open source ISA, it should be discussed at that level ... There are already extensions which are designed this
