Hi, I'm looking into the possibility of adding a SPIR-V (https://www.khronos.org/registry/spir-v) backend to GCC or as a plug-in. The output of which would be binary from the compiler, not binutils, with an option to extract a textual representation using an -f flag. The positive of this would be that any language that GCC supports could be used for GPGPU and graphics shading.
But would the GCC IR exception (mentioned in https://www.gnu.org/licenses/gcc-exception-3.1-faq.html) cause any SPIR-V output from GCC become GPLv3 licenced? I have also posted this to the GCC ML for discussion as I don't think it's clear whether or not something like SPIR-V would fall under Target Code or IR. Thanks, Luke A. Guest. P.S: I currently cannot post from my domain for some reason. I don't know why.
