The Flang and Clang drivers are separate but many Clang flags make sense for Flang, because they are not language specific. Here is a list of flags that Flang should support.
As these are documented on https://clang.llvm.org/docs/ClangCommandLineReference.html, I will only list the option, not what it does.
# currently known to be blocking, e.g. in Spack and CMake use cases
- [ ] -w, --no-warnings
- [ ] -mtune, -march, -mcpu
- [ ] -Qunused-arguments
# not known to be blockers but things I use regularly
- [ ] -Wl and -Xlinker
- [ ] -framework (MacOS-specific AFAIK)
- [ ] -time
- [ ] -static-openmp
# generally useful in LLVM projects
- [ ] -mllvm
- [ ] -mmlir
# code generation flags that have known utility
- [ ] -mno-gather
- [ ] -mno-scatter
- [ ] -mrecip
