From 47e06c6d4e542e47fcbad69a78c2436a854a0779 Mon Sep 17 00:00:00 2001 From: gus knight Date: Mon, 27 Jul 2015 16:03:25 -0400 Subject: Reorganize the source tree. * Documentation is now in "docs". * Source code is now in "src". * Misc. fixes here and there so that everything still works. I think I got everything in this commit, but I only tested this on Linux (Make) and Windows (CMake), so I might've messed something up on other platforms... --- src/conftest.c | 77 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 77 insertions(+) create mode 100644 src/conftest.c (limited to 'src/conftest.c') diff --git a/src/conftest.c b/src/conftest.c new file mode 100644 index 0000000..fa07a1b --- /dev/null +++ b/src/conftest.c @@ -0,0 +1,77 @@ +#include + +/* Define architecture */ +#if defined(__i386__) +# define TRIPLET_ARCH "i386" +#elif defined(__x86_64__) +# define TRIPLET_ARCH "x86_64" +#elif defined(__arm__) +# define TRIPLET_ARCH "arm" +#elif defined(__aarch64__) +# define TRIPLET_ARCH "aarch64" +#else +# define TRIPLET_ARCH "unknown" +#endif + +/* Define OS */ +#if defined (__linux__) +# define TRIPLET_OS "linux" +#elif defined (__FreeBSD__) || defined (__FreeBSD_kernel__) +# define TRIPLET_OS "kfreebsd" +#elif !defined (__GNU__) +# define TRIPLET_OS "unknown" +#endif + +/* Define calling convention and ABI */ +#if defined (__ARM_EABI__) +# if defined (__ARM_PCS_VFP) +# define TRIPLET_ABI "gnueabihf" +# else +# define TRIPLET_ABI "gnueabi" +# endif +#else +# define TRIPLET_ABI "gnu" +#endif + +#ifdef __GNU__ +# define TRIPLET TRIPLET_ARCH "-" TRIPLET_ABI +#else +# define TRIPLET TRIPLET_ARCH "-" TRIPLET_OS "-" TRIPLET_ABI +#endif + +#if defined(_WIN32) +int _CRT_glob = 0; +#endif + +int main(int argc, char *argv[]) +{ + switch(argc == 2 ? argv[1][0] : 0) { + case 'b': + { + volatile unsigned foo = 0x01234567; + puts(*(unsigned char*)&foo == 0x67 ?
