2012-07-19Adds the family codes for the Midview Atom processors so that thePreston Gurd
Atom buildbot will auto-detect Atom. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160521 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-18This patch fixes 8 out of 20 unexpected failures in "make check"Preston Gurd
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. The fix for this problem is in Host.cpp and X86Subtarget.cpp, but shall remain commented out until the current set of Atom test failures are fixed. Patch by Andy Zhang and Tyler Nowicki! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160451 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-26Implement getHostCPUName for ARM/linux. This will be used to implement ↵Benjamin Kramer
-march=native in clang. The cpuid registers are only available in privileged mode so we don't have an OS-independent way of implementing this. ARM doesn't provide a list of processor IDs so the list is somewhat incomplete. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159228 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-12Fixes for PPC host detection and features.Hal Finkel
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158363 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-12Reapply r158337, this time properly protect Darwin/PPC host CPU use with ↵Hal Finkel
__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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158349 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-12Revert r158337 "Move PPC host-CPU detection logic from PPCSubtarget into ↵Jakob Stoklund Olesen
sys::getHostCPUName()." This commit broke most of the PowerPC unit tests when running on Intel/Apple. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158345 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
