Any news on std::experimental::source_location (and/or _builtin_FILE etc.)

Clang Frontend

Hi all,

I recently tried to implement certain error handling boilerplate without the use of macros. source_location as described in http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4519.pdf would be a perfect fit for this.

I was able to implement source_location in gcc via __builtin_FILE(), __builtin_LINE(), etc. clang does not support these yet. I found two review requests (⚙ D36389 Add source location builtins and https://reviews.llvm.org/D37035) that seemed to be working on source_location and the builtins.
Are there any plans for integrating either the builtins or full fledged source_location?

regards

Fabio

Yes, there are plans to do both.

I haven’t been able to update/finish the patches due to school work, but I plan to
land both the builtins and source_location over the Christmas break.
