* Select bdver2 instead of bdver1 if TBM support is present on models < 0x10.Kaelyn Takata2014-05-05
| | | | | | | | | | Tested that the right -target-cpu is set in the clang -cc1 command line when running "clang -march=native -E -v - </dev/null" on both an FX-8150 and an FX-8350. Both are family 15h; the FX-8150 (Bulldozer processor) reports a model number of 1, and the FX-8350 (Piledriver processor) reports a model number of 2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207973 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | As on other hosts, the CPU identification instruction is priveleged, so we need to look through /proc/cpuinfo. I copied the PowerPC way of handling "generic".

* Make host ARM CPU feature detection independent of the vendorTobias Grosser2013-06-11
| | | | | | | | | | | | For ARM on linux we use /proc/cpuinfo to detect the host CPU's features. Linux derives these values without ever looking at the vendor of the specific CPU implementation. Hence, it adds little value, if we parse the output of /proc/cpuinfo only for certain vendors. This patch enables us to derive the correct feature flags e.g. for Qualcomm CPUs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183790 91177308-0d34-0410-b5e6-96231b3b80d8
* Allow host triple to be correctly overridden in CMake buildsTim Northover2013-05-04
| | | | | | | | | | | The intended semantics mirror autoconf, where the user is able to specify a host triple, but if it's left to the build system then "config.guess" is invoked for the default. This also renames the LLVM_HOSTTRIPLE define to LLVM_HOST_TRIPLE to fit in with the style of the surrounding defines. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181112 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce llvm::sys::getProcessTriple() function.Peter Collingbourne2013-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | In r143502, we renamed getHostTriple() to getDefaultTargetTriple() as part of work to allow the user to supply a different default target triple at configure time. This change also affected the JIT. However, it is inappropriate to use the default target triple in the JIT in most circumstances because this will not necessarily match the current architecture used by the process, leading to illegal instruction and other such errors at run time. Introduce the getProcessTriple() function for use in the JIT and its clients, and cause the JIT to use it. On architectures with a single bitness, the host and process triples are identical. On other architectures, the host triple represents the architecture of the host CPU, while the process triple represents the architecture used by the host CPU to interpret machine code within the current process. For example, when executing 32-bit code on a 64-bit Linux machine, the host triple may be 'x86_64-unknown-linux-gnu', while the process triple may be 'i386-unknown-linux-gnu'. This fixes JIT for the 32-on-64-bit (and vice versa) build on non-Apple platforms.

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-03
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | when run on an Intel Atom processor. The failures have arisen due to changes elsewhere in the trunk over the past 8 weeks or so. These failures were not detected by the Atom buildbot because the CPU on the Atom buildbot was not being detected as an Atom CPU.

* Use the cpuid 64 bit flag to pick the default CPU name for an unknown model.Bob Wilson2012-05-09
| | | | | | | | | | | 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
