Add explicit triples to AArch64 tests Only Linux is supported at the moment, and other platforms quickly fault. As a result these tests would fail on non-Linux hosts. It may be worth making the tests more generic again as more platforms are supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174170 91177308-0d34-0410-b5e6-96231b3b80d8

Add AArch64 as an experimental target. 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

Emit DWARF3 call frame information when DWARF3+ debug info is requested Currently, llvm always emits a DWARF CIE with a version of 1, even when emitting DWARF 3 or 4, which both support CIE version 3. This patch makes it emit the newer CIE version when we are emitting DWARF 3 or 4. This will not reduce compatibility, as we already emit other DWARF3/4 features, and is worth doing as the DWARF3 spec removed some ambiguities in the interpretation of call frame information. It also fixes a minor bug where the "return address" field of the CIE was encoded as a ULEB128, which is only valid when the CIE version is 3. There are no test changes for this, because (as far as I can tell) none of the platforms that we test have a return address register with a DWARF register number >127. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211272 91177308-0d34-0410-b5e6-96231b3b80d8
