2012-06-11Move PPC host-CPU detection logic from PPCSubtarget into sys::getHostCPUName().Hal Finkel
Both the new Linux functionality and the old Darwin functions have been moved. This change also allows this information to be queried directly by clang and other frontends (clang, for example, will now have real -mcpu=native support). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158337 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-02Use access(2) instead of stat(2) to check if a file exists.Benjamin Kramer
Apart from being slightly cheaper, this fixes a real bug that hits 32 bit linux systems. When passing a file larger than 2G to be linked (which isn't that uncommon with large projects such as WebKit), clang's driver checks if the file exists but the file size doesn't fit in an off_t and stat(2) fails with EOVERFLOW. Clang then says that the file doesn't exist instead of passing it to the linker. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157891 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-09Use the cpuid 64 bit flag to pick the default CPU name for an unknown model.Bob Wilson
For the Family 6 switch in sys::getHostCPUName, an unrecognized model was reported as "i686". That's a really bad default since it means that new CPUs will be treated as if they can only use 32-bit code. This just looks at the cpuid extended feature flag for 64 bit support, and if that is set, it uses a default x86-64 cpu. Similar logic is already used for the Family 15 code. <rdar://problem/11314502> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156486 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-04This patch adds a new NVPTX back-end to LLVM which supports code generation ↵Justin Holewinski
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.

2012-04-23[Support/Unix] Unconditionally include time.h.Michael J. Spencer
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
2012-04-23Conflict with st_dev/st_ino identifiers under Debian GNU/HurdSylvestre Ledru
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.
