* [AMDGPU] Fix s_branch with -1 offsetSam Kolton2016-09-191-5/+2
| | | | | | | | | | | | | | | | | | | Summary: In case s_branch instruction target is itself backend should emit offset -1 but instead it emit 0. ''' label: s_branch label // should emit [0xff,0xff,0x82,0xbf] ''' Tom, Matt: why are we adjusting fixup values in applyFixup() method instead of processFixup()? processFixup() is calling adjustFixupValue() but does nothing with its result.

* MC] Provide an MCTargetOptions to implementors of MCAsmBackendCtorTy, NFCJoel Jones2016-07-251-1/+2
| | | | | | | | | | | | | | | Some targets, notably AArch64 for ILP32, have different relocation encodings based upon the ABI. This is an enabling change, so a future patch can use the ABIName from MCTargetOptions to chose which relocations to use. Tested using check-llvm. The corresponding change to clang is in: http://reviews.llvm.org/D16538 Patch by: Joel Jones Differential Revision: https://reviews.llvm.org/D16213 llvm-svn: 276654
* Fix branch relaxation in 16-bit mode.Nirav Dave2016-07-111-1/+2
| | | | | | | | | | | | | | | Thread through MCSubtargetInfo to relaxInstruction function allowing relaxation to generate jumps with 16-bit sized immediates in 16-bit mode. This fixes PR22097.

* AMDGPU/SI: Refactor fixup handling for constant addrspace variablesTom Stellard2016-06-141-26/+7
| | | | | | | | | | | | | | | | | | | | | | Summary: We now use a standard fixup type applying the pc-relative address of constant address space variables, and we have the GlobalAddress lowering code add the required 4 byte offset to the global address rather than doing it as part of the fixup. This refactoring will make it easier to use the same code for global address space variables and also simplifies the code. Re-commit this after fixing a bug where we were trying to use a reference to a Triple object that had already been destroyed.

* Re-commit r247683: Replace Triple with a new TargetTuple in MCTargetDesc/* ↵Daniel Sanders2015-09-151-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | and related. NFC. Summary: This is the first patch in the series to migrate Triple's (which are ambiguous) to TargetTuple's (which aren't). For the moment, TargetTuple simply passes all requests to the Triple object it holds. Once it has replaced Triple, it will start to implement the interface in a more suitable way. This change makes some changes to the public C++ API. In particular, InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer() now take TargetTuples instead of Triples. The other public C++ API's have been left as-is for the moment to reduce patch size. This commit also contains a trivial patch to clang to account for the C++ API change. Thanks go to Pavel Labath for fixing LLDB for me.
