* Fixes for PPC host detection and features.Hal Finkel2012-06-121-1/+1
| | | | | | | | | POWER4 is a 64-bit CPU (better matched to the 970). The g3 is really the 750 (no altivec), the g4+ is the 74xx (not the 750). Patch by Andreas Tobler. llvm-svn: 158363

| | | | | | | | | | | | | __ppc__. Original commit message: Move PPC host-CPU detection logic from PPCSubtarget into sys::getHostCPUName(). 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). llvm-svn: 158349

* For llvm::sys::ThreadLocalImpl instead of malloc'ing the platform-specificArgyrios Kyrtzidis2012-06-122-13/+11
| | | | | | | | | | | thread local data, embed them in the class using a uint64_t and make sure we get compiler errors if there's a platform where this is not big enough. This makes ThreadLocal more safe for using it in conjunction with CrashRecoveryContext. Related to crash in rdar://11434201. llvm-svn: 158342

* Use access(2) instead of stat(2) to check if a file exists.Benjamin Kramer2012-06-021-2/+1
| | | | | | | | | | | 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. llvm-svn: 157891

* Set the default iOS version to 3.0.Chad Rosier2012-05-091-2/+4
| | | | llvm-svn: 156492
* Use the cpuid 64 bit flag to pick the default CPU name for an unknown model.Bob Wilson2012-05-091-1/+1
| | | | | | | | | | | 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> llvm-svn: 156486

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 llvm-svn: 155382
* 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. Patch by Pino Toscano llvm-svn: 155354
