Bug ID: 117221
Summary: Add smoketest for alternative compiler for libstdc++
headers (like CXX_UNDER_TEST)
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
Target Milestone: ---
Occasionally, we have bugs where Clang either can't parse libstdc++ headers as
a Clang bug, or where an error was made in a non-GCC or Clang-only conditional
(indirectly usually). (I can dig up more examples than PR117220 if needed).
We should have some easy way to test including all libstdc++ headers with an
alternative compiler like Clang, like CXX_UNDER_TEST does for ABI bits right
now.
