Replace -use-init-array with -use-ctors. We have been using .init-array for most systems for quiet some time, but tools like llc are still defaulting to .ctors because the old option was never changed. This patch makes llc default to .init-array and changes the option to be -use-ctors. Clang is not affected by this. It has its own fancier logic. llvm-svn: 216905

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. llvm-svn: 174054

[IR] Disallow llvm.global_ctors and llvm.global_dtors of the 2-field form in textual format The 3-field form was introduced by D3499 in 2014 and the legacy 2-field form was planned to be removed in LLVM 4.0 For the textual format, this patch migrates the existing 2-field form to use the 3-field form and deletes the compatibility code. test/Verifier/global-ctors-2.ll checks we have a friendly error message. For bitcode, lib/IR/AutoUpgrade UpgradeGlobalVariables will upgrade the 2-field form (add i8* null as the third field).

Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier debugging. No functionality change and all tests pass after conversion. This was done with the following sed invocation to catch label lines demarking function boundaries: sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct. llvm-svn: 186258
