This allows running the test suite against the native Standard Library on most systems, and against libstdc++ installed at a custom location. Of course, these configurations don't run 100% clean at the moment. In particular, running against the native stdlib is almost guaranteed not to work out-of-the-box, since the test suite generally contains tests for things that have been implemented on tip-of-trunk but not released to most major platforms yet. However, having an easy way to run the test suite against that library is still both useful and interesting.

# This testing configuration runs the test suite using the libstdc++ Standard library.
|
|
#
|
|
# The additional '--param libstdcxx-install-prefix=<PATH>', '--param libstdcxx-triple=<TRIPLE>' and
|
|
# '--param libstdcxx-version=<VERSION>' lit parameters must be provided when invoking lit for the
|
|
# configuration to find the appropriate headers and library.
|
|
#
|
|
# For example:
|
|
#
|
|
# $ ./libcxx/utils/libcxx-lit <BUILD> -sv libcxx/test/std --param libstdcxx-install-prefix=/opt/homebrew/Cellar/gcc/14.1.0_1 \
|
|
# --param libstdcxx-version=14 \
|
|
# --param libstdcxx-triple=aarch64-apple-darwin22
