* This patch adds a new NVPTX back-end to LLVM which supports code generation ↵Justin Holewinski2012-05-041-0/+18
| | | | | | | | | | | | | | | | | for NVIDIA PTX 3.0. This back-end will (eventually) replace the current PTX back-end, while maintaining compatibility with it. The new target machines are: nvptx (old ptx32) => 32-bit PTX nvptx64 (old ptx64) => 64-bit PTX The sources are based on the internal NVIDIA NVPTX back-end, and contain more functionality than the current PTX back-end currently provides.

* [Support/Unix] Unconditionally include time.h.Michael J. Spencer2012-04-231-8/+2
| | | | | | | | | | | | When building LLVM on Linux with libc++ with CMake TIME_WITH_SYS_TIME is undefined, and HAVE_SYS_TIME_H is defined. This ends up including sys/time.h but not time.h. Unix/TimeValue.inc requires time.h for asctime_r and localtime. libstdc++ seems to include time.h anyway, but libc++ does not. Fix this by always including time.h git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155382 91177308-0d34-0410-b5e6-96231b3b80d8
* Conflict with st_dev/st_ino identifiers under Debian GNU/HurdSylvestre Ledru2012-04-231-4/+4
| | | | | | | | | | | | | | | | The problem is that the struct file_status on UNIX systems has two members called st_dev and st_ino; those are also members of the struct stat, and they are reserved identifiers which can also be provided as #define (and this is the case for st_dev on Hurd). The solution (attached) is to rename them, for example adding a "fs_" prefix (= file status) to them.

When mapping the file there could be a racing issue that resulted in the file being larger than the FileSize passed by the caller.
