检测Nvidia的NVC++（不是NVCC）编译器和编译器版本

Question

我正在使用 Nvidia 的 HPC 编译器nvc++。

有没有办法检测程序是否正在使用特定的编译器和版本进行编译？

我在手册中找不到任何内容https://docs.nvidia.com/hpc-sdk/index.html。

另一个 Nvidia 相关的编译器nvcc有这些宏

__NVCC__
    Defined when compiling C/C++/CUDA source files.
__CUDACC__
    Defined when compiling CUDA source files.
__CUDACC_RDC__
    Defined when compiling CUDA source files in relocatable device code mode (see NVCC Options for Separate Compilation). 
__CUDACC_EWP__
    Defined when compiling CUDA source files in extensible whole program mode (see Options for Specifying Behavior of Compiler/Linker). 
__CUDACC_DEBUG__
    Defined when compiling CUDA source files in the device-debug mode (see Options for Specifying Behavior of Compiler/Linker). 
__CUDACC_RELAXED_CONSTEXPR__
    Defined when the --expt-relaxed-constexpr flag is specified on the command line. Refer to CUDA C++ Programming Guide for more details. 
__CUDACC_EXTENDED_LAMBDA__
    Defined when the --expt-extended-lambda or --extended-lambda flag is specified on the command line. Refer to CUDA C++ Programming Guide for more details. 
__CUDACC_VER_MAJOR__
    Defined with the major version number of nvcc. 
__CUDACC_VER_MINOR__
    Defined with the minor version number of nvcc. 
__CUDACC_VER_BUILD__
    Defined with the build version number of nvcc. 
__NVCC_DIAG_PRAGMA_SUPPORT__
    Defined when the CUDA frontend compiler supports diagnostic control with the nv_diag_suppress, nv_diag_error, nv_diag_warning, nv_diag_default, nv_diag_once, nv_diagnostic pragmas. 

但我找不到 的等效项nvc++。该strings命令没有显示任何合适的宏名称候选。

$ strings /opt/nvidia/hpc_sdk/Linux_x86_64/22.1/compilers/bin/nvc++ | grep D

Answer 1

__NVCOMPILER __NVCOMPILER_MAJOR__ __NVCOMPILER_MINOR__

在随机的第三方库中意外发现它们https://github.com/fmtlib/fmt/blob/master/include/fmt/core.h

#ifdef __NVCOMPILER
#  define FMT_NVCOMPILER_VERSION \
    (__NVCOMPILER_MAJOR__ * 100 + __NVCOMPILER_MINOR__)
#else
#  define FMT_NVCOMPILER_VERSION 0
#endif
