* Rename and adjust processFixupValue.Rafael Espindola2017-06-301-9/+6
| | | | | | | It was not processing any value. All that it ever did was force relocations, so name it shouldForceRelocation. llvm-svn: 306906

* ARM: move some logic from processFixupValue to applyFixup.Rafael Espindola2017-06-231-1/+2
| | | | | | | | | | | | processFixupValue is called on every relaxation iteration. applyFixup is only called once at the very end. applyFixup is then the correct place to do last minute changes and value checks. While here, do proper range checks again for fixup_arm_thumb_bl. We used to do it, but dropped because of thumb2. We now do it again, but use the thumb2 range. llvm-svn: 306177

* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787

* Add MCContext argument to MCAsmBackend::applyFixup for error reportingAlex Bradbury2017-04-051-1/+2
| | | | | | | | | | | | | | | | A number of backends (AArch64, MIPS, ARM) have been using MCContext::reportError to report issues such as out-of-range fixup values in their TgtAsmBackend. This is great, but because MCContext couldn't easily be threaded through to the adjustFixupValue helper function from its usual callsite (applyFixup), these backends ended up adding an MCContext* argument and adding another call to applyFixup to processFixupValue. Adding an MCContext parameter to applyFixup makes this unnecessary, and even better - applyFixup can take a reference to MCContext rather than a potentially null pointer.

* Replace "fallthrough" comments with LLVM_FALLTHROUGHJustin Bogner2016-08-171-2/+2
| | | | | | | This is a mechanical change of comments in switches like fallthrough, fall-through, or fall-thru to use the LLVM_FALLTHROUGH macro instead. llvm-svn: 278902
* 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.

* Re-commit r247683: Replace Triple with a new TargetTuple in MCTargetDesc/* ↵Daniel Sanders2015-09-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
