From 8601733c1cec09bbda859129eb00a560dca034bb Mon Sep 17 00:00:00 2001 From: Artem Belevich Date: Tue, 17 Nov 2015 22:28:55 +0000 Subject: [CUDA] Make CUDA compilation usable by default. Currently clang requires several additional command line options in order to enable new features needed during CUDA compilation. This patch makes these options default. * Automatically include cuda_runtime.h if we've found a valid CUDA installation. * Disable automatic CUDA header inclusion during unit tests. * Added test case for command line construction. * Enabled target overloads and relaxed call checks that are needed in order to include CUDA headers. * Added CUDA-7.5 installation path to the CUDA installation search list. * Define __CUDA__ macro to indicate CUDA compilation. llvm-svn: 253389 --- clang/lib/Frontend/InitPreprocessor.cpp | 2 ++ 1 file changed, 2 insertions(+) (limited to 'clang/lib/Frontend/InitPreprocessor.cpp') diff --git a/clang/lib/Frontend/InitPreprocessor.cpp b/clang/lib/Frontend/InitPreprocessor.cpp index 30bf118..15aa546 100644 --- a/clang/lib/Frontend/InitPreprocessor.cpp +++ b/clang/lib/Frontend/InitPreprocessor.cpp @@ -411,6 +411,8 @@ static void InitializeStandardPredefinedMacros(const TargetInfo &TI, // Not "standard" per se, but available even with the -undef flag. if (LangOpts.AsmPreprocessor) Builder.defineMacro("__ASSEMBLER__"); + if (LangOpts.CUDA) + Builder.defineMacro("__CUDA__"); } /// Initialize the predefined C++ language feature test macros defined in -- cgit v1.1
