Bug ID: 111390
Summary: 'make check-compile' target is not useful
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
Target Milestone: ---
This makefile target does compilation-only testing, to check that tests can be
built. But there's no parallelism, so it takes ages. Worse, it ignores dejagnu
directives so just runs everything with a default set of options, including the
implicit -std=gnu++17
This means that all C++20 and later tests fail. And any XFAIL tests with
dg-error directives "fail" noisily.
I'm not sure it is useful to keep it.
If we want to do compilation-only testing, I think it would be better to modify
the dejagnu procs so that "do-do run" tests are treated as "dg-do compile".
