Question about the default compiler used in the frond end of Bambu.

Hi, Sorry, I still have a question about the default compiler used in the front end of Bambu. Is it GCC？ Are tasks in the front end done by GCC? Are plug-ins implemented based on GCC?

Hello, The default compiler selected by Bambu depends on the build configuration and is decided by the logic in CompilerWrapper::getDefaultCompiler. If you are using one of the official AppImages, it is probably GCC 4.9.4. I would suggest using the --compiler=<compiler_name> flag to set the frontend compiler to avoid doubts. Frontend plugins have one GCC-based and one LLVM-based version performing the same tasks whether the selected compiler is GCC or LLVM. The only exception is for the pragma parser, which is only implemented as a Clang frontend plugin: in this case, selecting an LLVM compiler will enable full pragma support, while choosing a GCC frontend will handle a smaller subset of HLS pragmas (HLS inline and HLS unroll will not work, but they can still be converted to GCC directives and attributes).
