Hello Qwert Nerdish You asked on gcc-help mailing list about RTL to LLVM bitcode conversion in https://gcc.gnu.org/pipermail/gcc-help/2025-April/144133.html > Clang can emit LLVM bitcode via -emit-llvm. llvmgcc replaces RTL with LLVM > IR instead, but this is not what i'm looking for. This could written as ( > https://gcc.gnu.org/onlinedocs/gccint/Back-End.html) backend, where GCC > compiles RTL down to LLVM IR using assembly file as output. I would recommend experimenting such a converter at first as a GCC plugin, and probably starting from GIMPLE/SSA representation (mostly target neutral), not the target specific RTL one. I am not familiar with LLVM bitcode but I was told it is not much target specific and was inspired (longtime ago) by Gimple. Some old ideas from https://arxiv.org/abs/1109.0779 could be relevant, even if related code (e.g. https://github.com/bstarynk/bismon ...) is not immediately compatible with current GCC (it was with old GCC 12 one).
