| | | | | | | | | | It's fishy to be changing the `std::vector<>` owned by the iterator, and no one actual does it, so I'm going to remove the ability in a subsequent commit. First, update the users. <rdar://problem/14292693> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207252 91177308-0d34-0410-b5e6-96231b3b80d8

* Support: generalise object type handling for WindowsSaleem Abdulrasool2014-03-31
| | | | | | | | | This generalises the object file type parsing to all Windows environments. This is used by cygwin as well as MSVC environments for MCJIT. This also makes the triple more similar to Chandler's suggestion of a separate field for the object file format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205219 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM64: remove -m32/-m64 mapping with ARM.Tim Northover2014-03-30
| | | | | | | This is causing the ARM build-bots to fail since they only include the ARM backend and can't create an ARM64 target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205132 91177308-0d34-0410-b5e6-96231b3b80d8
* Support: correct Windows normalisationSaleem Abdulrasool2014-03-30
| | | | | | | | | | | | | If the environment is unknown and no object file is provided, then assume an "MSVC" environment, otherwise, set the environment to the object file format. In the case that we have a known environment but a non-native file format for Windows (COFF) which is used for MCJIT, then append the custom file format to the triple as an additional component. This fixes the MCJIT tests on Windows. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205130 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM64: initial backend importTim Northover2014-03-29
| | | | | | | | | | | | This adds a second implementation of the AArch64 architecture to LLVM, accessible in parallel via the "arm64" triple. The plan over the coming weeks & months is to merge the two into a single backend, during which time thorough code review should naturally occur. Everything will be easier with the target in-tree though, hence this commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205090 91177308-0d34-0410-b5e6-96231b3b80d8
* Canonicalise Windows target triple spellingsSaleem Abdulrasool2014-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | Construct a uniform Windows target triple nomenclature which is congruent to the Linux counterpart. The old triples are normalised to the new canonical form. This cleans up the long-standing issue of odd naming for various Windows environments. There are four different environments on Windows: MSVC: The MS ABI, MSVCRT environment as defined by Microsoft GNU: The MinGW32/MinGW32-W64 environment which uses MSVCRT and auxiliary libraries Itanium: The MSVCRT environment + libc++ built with Itanium ABI Cygnus: The Cygwin environment which uses custom libraries for everything The following spellings are now written as: i686-pc-win32 => i686-pc-windows-msvc i686-pc-mingw32 => i686-pc-windows-gnu i686-pc-cygwin => i686-pc-windows-cygnus This should be sufficiently flexible to allow us to target other windows environments in the future as necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204977 91177308-0d34-0410-b5e6-96231b3b80d8

* [ADT] Update PointerIntPair to handle pointer types with more than 31 bits free.Jordan Rose2014-03-07
| | | | | | | | | | Previously, the assertions in PointerIntPair would try to calculate the value (1 << NumLowBitsAvailable); the inferred type here is 'int', so if there were more than 31 bits available we'd get a shift overflow. Also, add a rudimentary unit test file for PointerIntPair. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203273 91177308-0d34-0410-b5e6-96231b3b80d8

* Support: split object format out of environmentSaleem Abdulrasool2014-03-06
| | | | | | | | | | | This is a preliminary setup change to support a renaming of Windows target triples. Split the object file format information out of the environment into a separate entity. Unfortunately, file format was previously treated as an environment with an unknown OS. This is most obvious in the ARM subtarget where the handling for macho on an arbitrary platform switches to AAPCS rather than APCS (as per Apple's needs). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203160 91177308-0d34-0410-b5e6-96231b3b80d8

* Tweak an _MSC_VER ifdef to use typename with clang in a unittestReid Kleckner2014-02-13
| | | | | | | | | | | In theory, Clang should figure out how to parse this correctly without typename, but since this is the last TU that Clang falls back on in the self-host, I'm going to compromise and check for __clang__.

* Roll back the ConstStringRef change for nowAlp Toker2014-01-27
| | | | | | | | | | | There are a couple of interesting things here that we want to check over (particularly the expecting asserts in StringRef) and get right for general use in ADT so hold back on this one. For clang we have a workable templated solution to use in the meanwhile. This reverts commit r200187. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200194 91177308-0d34-0410-b5e6-96231b3b80d8
* StringRef: Extend constexpr capabilities and introduce ConstStringRefAlp Toker2014-01-27
| | | | | | | | | | | | | | | | | | | (1) Add llvm_expect(), an asserting macro that can be evaluated as a constexpr expression as well as a runtime assert or compiler hint in release builds. This technique can be used to construct functions that are both unevaluated and compiled depending on usage. (2) Update StringRef using llvm_expect() to preserve runtime assertions while extending the same checks to static asserts in C++11 builds that support the feature. (3) Introduce ConstStringRef, a strong subclass of StringRef that references compile-time constant strings. It's convertible to, but not from, ordinary StringRef and thus can be used to add compile-time safety to various interfaces in LLVM and clang that only accept fixed inputs such as diagnostic format strings that tend to get misused. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200187 91177308-0d34-0410-b5e6-96231b3b80d8

* [APInt] Fixed bug where APInt(UINT32_MAX, 0) would blow up when being ↵Michael Gottesman2014-01-19

After the computation is complete, the uint64_t is truncated when the function returns. I know that this is not something that is likely to happen, but it *IS* a valid input and we should not blow up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199609 91177308-0d34-0410-b5e6-96231b3b80d8
