* AArch64: add CMake dependency to fix very parallel buildsTim Northover2013-05-181-0/+2
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182190 91177308-0d34-0410-b5e6-96231b3b80d8
* AArch64: implement large code model access to global variables.Tim Northover2013-05-041-1/+8
| | | | | | | | | | | | | | The MOVZ/MOVK instruction sequence may not be the most efficient (a literal-pool load could be better) but adding that would require reinstating the ConstantIslands pass. For now the sequence is correct, and that's enough. Beware, as of commit GNU ld does not appear to support the relocations needed for this. Its primary purpose (for now) will be to support JITed code, since in that case there is no guarantee of where your code will end up in memory relative to external symbols it references. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181117 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix undefined behavior in AArch64David Majnemer2013-04-111-7/+11
| | | | | | | | | A64Imms::isLogicalImmBits and A64Imms::isLogicalImm will attempt to execute shifts that perform undefined behavior. Instead of attempting to perform the 64-bit rotation, treat it as a no-op. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179317 91177308-0d34-0410-b5e6-96231b3b80d8
* AArch64: implement ETMv4 trace system registers.Tim Northover2013-04-032-0/+432

* Add icache prefetch operations to AArch64Tim Northover2013-02-062-0/+12
| | | | | | | This adds hints to the various "prfm" instructions so that they can affect the instruction cache as well as the data cache. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174495 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix formatting in AArch64 backend.Tim Northover2013-02-051-1/+2
| | | | | | | | | | | 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 Northover2013-02-055-0/+1633
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
