* AArch64: add block comments where missingTim Northover2013-02-141-0/+5
| | | | | | Only comments affected. No code change at all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175169 91177308-0d34-0410-b5e6-96231b3b80d8
* AArch64: Simplify logic in deciding whether bfi is validTim Northover2013-02-111-6/+1
| | | | | | | | Previous code had a confusing comment which was mostly an implementation detail. This condition corresponds to "lsb up to register width" and "width not ridiculous". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174877 91177308-0d34-0410-b5e6-96231b3b80d8
* Make use of DiagnosticType to provide better AArch64 diagnostics.Tim Northover2013-02-111-4/+164
| | | | | | | | | This gives a DiagnosticType to all AsmOperands in sight. This replaces all "invalid operand" diagnostics with something more specific. The messages given should still be sufficiently vague that they're not usually actively misleading when LLVM guesses your instruction incorrectly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174871 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix remaining StringRef abuse.Tim Northover2013-02-051-2/+2
| | | | | | This should fix the valgrind buildbot failure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174375 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix formatting in AArch64 backend.Tim Northover2013-02-051-5/+7
| | | | | | | | | | | This should fix three purely whitespace issues: + 80 column violations. + Tab characters. + TableGen brace placement. No functional changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174370 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove cyclic dependency in AArch64 librariesTim Northover2013-02-051-1/+1
| | | | | | | | This moves the bit twiddling and string fiddling functions required by other parts of the backend into a separate library. Previously they resided in AArch64Desc, which created a circular dependency between various components. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174369 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix some abuses of StringRefTim Northover2013-02-041-3/+4
| | | | | | We were taking a StringRef to a temporary result, which can go horribly wrong. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174328 91177308-0d34-0410-b5e6-96231b3b80d8
* Add AArch64 as an experimental target.Tim Northover2013-01-314-0/+2071
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
