globals deleted by "remove comments" when viewing LLVM IR via -emit-llvm

See original GitHub issue

I often use compiler explorer with a -emit-llvm flag to view the LLVM IR produced by Clang / LLVM’s middle-end optimizers. This generally works pretty well (and even syntax-highlights fairly nicely), but the “remove comments” option strips out lines starting with an @, which deletes all the global variables!

Some better support for viewing LLVM IR output would be great (per #288), but if that’s a long way off, something as simple as detecting -emit-llvm in the command line and not treating lines starting with @ as comments would be marvelous.

Hi - I’ve now improved how we detect when the compiler is asked to emit the IR and we properly filter it now. Sorry that this got forgotten. The fix should hit the live site shortly 😃
