Bug ID: 102350
Summary: __builtin_source_location not available in earlier
language modes
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: pdimov at gmail dot com
Target Milestone: ---
Currently, `__builtin_source_location` requires (a) `<source_location>` to be
included and (b) -std=c++20. Are there good reasons for these restrictions? The
builtin would still be extremely valuable in earlier language modes.
Libraries that still support 03/11/14/17 (Boost.System, for instance) could
transparently supply source locations by using a default `void const* loc =
__builtin_source_location()` argument.
