* Move the global variables representing each Target behind accessor functionMehdi Amini2016-10-091-9/+8
| | | | | | | | This avoids "static initialization order fiasco" Differential Revision: https://reviews.llvm.org/D25412 llvm-svn: 283702
* Delete MCCodeGenInfo.Rafael Espindola2016-06-301-12/+0
| | | | | | | MC doesn't really care about CodeGen stuff, so this was just complicating target initialization. llvm-svn: 274258
* Delete Reloc::Default.Rafael Espindola2016-05-181-2/+0
| | | | | | | | | | | | Having an enum member named Default is quite confusing: Is it distinct from the others? This patch removes that member and instead uses Optional<Reloc> in places where we have a user input that still hasn't been maped to the default value, which is now clear has no be one of the remaining 3 options. llvm-svn: 269988

* [mips] Make Static a default relocation model for MIPS codegenPetar Jovanovic2016-04-111-3/+1
| | | | | | | | | | | | This change follows up defaults for GCC and Clang, so LLVM does not differ from them. While number of the test files are touched with this change, they all keep the old (expected) behaviour with the explicit option: "-relocation-model=pic" The tests that have not been touched are insensitive to relocation model.

* Re-commit r247683: Replace Triple with a new TargetTuple in MCTargetDesc/* ↵Daniel Sanders2015-09-151-9/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* MC: Remove MCSubtargetInfo() default constructorDuncan P. N. Exon Smith2015-07-101-3/+1
| | | | | | | | | | | | | | | | | | | | | Force all creators of `MCSubtargetInfo` to immediately initialize it, merging the default constructor and the initializer into an initializing constructor. Besides cleaning up the code a little, this makes it clear that the initializer is never called again later. Out-of-tree backends need a trivial change: instead of calling: auto *X = new MCSubtargetInfo(); InitXYZMCSubtargetInfo(X, ...); return X; they should call: return createXYZMCSubtargetInfoImpl(...); There's no real functionality change here. llvm-svn: 241957
* Change the last few internal StringRef triples into Triple objects.Daniel Sanders2015-07-061-2/+2
| | | | | | | | | | | | | | | | | | | | Summary: This concludes the patch series to eliminate StringRef forms of GNU triples from the internals of LLVM that began in r239036. At this point, the StringRef-form of GNU Triples should only be used in the public API (including IR serialization) and a couple objects that directly interact with the API (most notably the Module class). The next step is to replace these Triple objects with the TargetTuple object that will represent our authoratative/unambiguous internal equivalent to GNU Triples.

| | | | | | | | | | | | | | | | | Summary: This should fix the MCJIT unit tests that were broken by r201792 on the MIPS buildbot. MIPS currently uses the default implementation of sys::getHostCPUName() which always returns "generic". For now, we will accept "generic" and coerce it to "mips32" or "mips64" depending on the target architecture like we do for empty CPU names.

Removed -mcpu from blez_bgez.ll and const-mult.ll to cover the default case. Ideally, the two implementations of selectMipsCPU() will be merged but it's proven difficult to find a home for the function that doesn't cause link errors. For now, we'll hoist the common functionality into a function and mark it with FIXME's.

If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class.

| | | | | | | | | | | | | This patch fixes an old FIXME by creating a MCTargetStreamer interface and moving the target specific functions for ARM, Mips and PPC to it. The ARM streamer is still declared in a common place because it is used from lib/CodeGen/ARMException.cpp, but the Mips and PPC are completely hidden in the corresponding Target directories. I will send an email to llvmdev with instructions on how to use this. llvm-svn: 192181
* Remove some really nasty uses of hasRawTextSupport.Rafael Espindola2013-10-051-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When MC was first added, targets could use hasRawTextSupport to keep features working before they were added to the MC interface. The design goal of MC is to provide an uniform api for printing assembly and object files. Short of relaxations and other corner cases, a object file is just another representation of the assembly. It was never the intention that targets would keep doing things like if (hasRawTextSupport()) Set flags in one way. else Set flags in another way. When they do that they create two code paths and the object file is no longer just another representation of the assembly. This also then requires testing with llc -filetype=obj, which is extremelly brittle. This patch removes some of these hacks by replacing them with smaller ones. The ARM flag setting is trivial, so I just moved it to the constructor. For Mips, the patch adds two temporary hack directives that allow the assembly to represent the same things as the object file was already able to. The hope is that the mips developers will replace the hack directives with the same ones that gas uses and drop the -print-hack-directives flag. I will also try to implement a target streamer interface, so that we can move this out of the common code. In summary, for any new work, two rules of the thumb are * Don't use "llc -filetype=obj" in tests. * Don't add calls to hasRawTextSupport. llvm-svn: 192035
* Remove the MachineMove class.Rafael Espindola2013-05-131-4/+4
| | | | | | | | | | | | It was just a less powerful and more confusing version of MCCFIInstruction. A side effect is that, since MCCFIInstruction uses dwarf register numbers, calls to getDwarfRegNum are pushed out, which should allow further simplifications. I left the MachineModuleInfo::addFrameMove interface unchanged since this patch was already fairly big. llvm-svn: 181680
