我正在尝试根据 LLVM's Test Suite Guide使用 llvm testsuite 运行 SPEC2017 基准测试。我的 cmake 命令成功，但使用 make，我在包含文件（如 numeric_traits.h）中出现错误。每次出现__is_signalinnumeric_traits.h和时，我都会收到错误消息stl_algobase.h。

CMake 命令：

$ cmake -DCMAKE_C_COMPILER:STRING="/usr/bin/clang-7" -DCMAKE_CXX_COMPILER:STRING="/usr/bin/clang++-7" -DCMAKE_C_FLAGS="-fPIC" -C../test-suite/cmake/caches/O3.cmake -DTEST_SUITE_SPEC2017_ROOT:STRING="../speccpu2017" ../test-suite
...
$ make
...

将此放入 CXX 的可移植性标志中https://www.spec.org/cpu2017/Docs/benchmarks/flags/526.blender_r.flags.html#b526.blender_r_D__BOOL_DEFINED

仅供参考，<SPEC_SRC>/config/Example-clang-llvm-linux-x86.cfg或<SPEC_SRC>/config/Example-aocc-linux-x86.cfg包含特定于 Clang 的可移植性标志。
