exceptions in llvm projects

Project Infrastructure LLVM Dev List Archives

While creating compiler transformations for use with opt, I discovered that when configuring and making LLVM and its projects, exceptions are disabled. I'm assuming that was done for performance reasons. Is there any reason not to enable exceptions for LLVM projects?

Thanks,

That's correct. It makes LLVM slightly smaller too. Note that the tools
and a few libraries not not exception free at this point. Any Makefile
that has REQUIRES_EH:=1 in it will build with exceptions enabled.

Nope. Have at it. Just don't expect to catch many (any?) from LLVM.
