Benjamin Kramer 172f80849f Use access(2) instead of stat(2) to check if a file exists. 
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.

Bob Wilson 8d4e2fab63 Use the cpuid 64 bit flag to pick the default CPU name for an unknown model. 
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>

Justin Holewinski ae556d3ef7 This patch adds a new NVPTX back-end to LLVM which supports code generation 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.

Michael J. Spencer 04b795bc1d [Support/Unix] Unconditionally include time.h. 
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

Sylvestre Ledru 3099f4bda8 Conflict with st_dev/st_ino identifiers under Debian GNU/Hurd 
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.

Benjamin Kramer 94988cb34c SmallPtrSet: Reuse DenseMapInfo's pointer hash function instead of inventing a bad one ourselves. 
DenseMap's hash function uses slightly more entropy and reduces hash collisions
significantly.  I also experimented with Hashing.h, but it didn't gave a lot of
improvement while being much more expensive to compute.
