* Add AArch64 as an experimental target.Tim Northover2013-01-31192-13/+45628
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for AArch64 (ARM's 64-bit architecture) to LLVM in the "experimental" category. Currently, it won't be built unless requested explicitly. This initial commit should have support for: + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions (except the late addition CRC instructions). + CodeGen features required for C++03 and C99. + Compilation for the "small" memory model: code+static data < 4GB. + Absolute and position-independent code. + GNU-style (i.e. "__thread") TLS. + Debugging information. The principal omission, currently, is performance tuning. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174054 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove Attribute::hasAttributes() and make Attribute::hasAttribute() private.Bill Wendling2013-01-313-21/+9
| | | | | | | | The Attribute::hasAttributes() is kind of meaningless since an Attribute can have only one attribute.
