From ef4b8d817181f42d99a2c9664367d60fc3a74c05 Mon Sep 17 00:00:00 2001 From: Martin Nowack Date: Thu, 12 Oct 2023 10:32:32 +0100 Subject: Replace `%libcxx_include` with `%libcxx_includes` for multi-include directories To support multiple include directories for c++ header files, use `%libcxx_includes`. This string contains the `-I` compiler directive for each include path as well. Update test cases to use new directive. --- test/CXX/symex/libc++/atexit.cpp | 2 +- test/CXX/symex/libc++/can_catch_test.cpp | 2 +- test/CXX/symex/libc++/catch_recover.cpp | 2 +-
