Note: one motivation for this PR is to support #11245. |
Ensure that `LOG(FATAL)` always resolves to calling `[[noreturn]]` code. This has two benefits: - Helps developers more quickly understand the intended/required behavior for `LOG(FATAL)` calls. - May eliminate spurious compiler warnings based on control-flow analysis. E.g. gcc's / clang's `-Wno-return` warnings.

There was a problem hiding this comment.
Sounds like this will silence the llvm warnings that force us to put empty returns after LOG(FATAL). Thanks!

That was my intent, but I'm not sure it's actually effective, at least with the gcc / clang builds I tried. Hopefully newer/future versions of those compilers will be smarter about this. |
