* ELF: Include archive names in error messages.Rui Ueyama2016-02-027-14/+43
| | | | | | | | If object files are drawn from archive files, the error message should be something like "conflict symbols in foo.a(bar.o) and baz.o" instead of "conflict symbols in bar.o and baz.o". This patch implements that. llvm-svn: 259475

* [RegisterCoalescer] Better DebugLoc for reMaterializeTrivialDefDavid Majnemer2016-02-022-0/+58
| | | | | | | | | | When rematerializing a computation by replacing the copy, use the copy's location. The location of the copy is more representative of the original program. This partially fixes PR10003. llvm-svn: 259469

* [LCG] Build an edge abstraction for the LazyCallGraph and use it toChandler Carruth2016-02-025-248/+418
| | | | | | | | | | | | | | | | | | | | | differentiate between indirect references to functions an direct calls. This doesn't do a whole lot yet other than change the print out produced by the analysis, but it lays the groundwork for a very major change I'm working on next: teaching the call graph to actually be a call graph, modeling *both* the indirect reference graph and the call graph simultaneously. More details on that in the next patch though. The rest of this is essentially a bunch of over-engineering that won't be interesting until the next patch. But this also isolates essentially all of the churn necessary to introduce the edge abstraction from the very important behavior change necessary in order to separately model the two graphs. So it should make review of the subsequent patch a bit easier at the cost of making this patch seem poorly motivated. ;] Differential Revision: http://reviews.llvm.org/D16038 llvm-svn: 259463

* [LVI] Introduce an intersect operation on lattice valuesPhilip Reames2016-02-023-32/+160
| | | | | | | | | | | | LVI has several separate sources of facts - edge local conditions, recursive queries, assumes, and control independent value facts - which all apply to the same value at the same location. The existing implementation was very conservative about exploiting all of these facts at once. This change introduces an "intersect" function specifically to abstract the action of picking a good set of facts from all of the separate facts given. At the moment, this function is relatively simple (i.e. mostly just reuses the bits which were already there), but even the minor additions reveal the inherent power. For example, JumpThreading is now capable of doing an inductive proof that a particular value is always positive and removing a half range check. I'm currently only using the new intersect function in one place. If folks are happy with the direction of the work, I plan on making a series of small changes without review to replace mergeIn with intersect at all the appropriate places.

| | | | | | | | | Fix a crash in `getMemOpBaseRegImmOfs` that happens if the base of `MemOp` is a frame index memory operand. The fix is to have `getMemOpBaseRegImmOfs` bail out in such cases. We can possibly be more clever here, if needed. llvm-svn: 259456

* Set ordinals of all File's created in MachO passes.Pete Cooper2016-02-025-5/+15
| | | | | | | | | | | When we do debug printing of atoms, they expect their parent file to have an ordinal. Right now we trigger a bunch of asserts. This doesn't actually manifest in differences in any real tests, but even if the only thing it does is improve debuggability then its still useful. llvm-svn: 259450
* [X86][FastISel] Don't force Nearest-Even rounding for VCVTPS2PH, use MXCSR.Ahmed Bougacha2016-02-022-3/+5
| | | | | | FastISel counterpart to r259448. llvm-svn: 259449
* [X86] Don't force Nearest-Even rounding for VCVTPS2PH, use MXCSR.Ahmed Bougacha2016-02-023-6/+11
| | | | | | | | | | | | | | | | | | Officially, we don't acknowledge non-default configurations of MXCSR, as getting there would require usage of the FENV_ACCESS pragma (at least insofar as rounding mode is concerned). We don't support the pragma, so we can assume that the default rounding mode - round to nearest, ties to even - is always used. However, it's inconsistent with the rest of the instruction set, where MXCSR is always effective (unless otherwise specified). Also, it's an unnecessary obstacle to the few brave souls that use fenv.h with LLVM. Avoid the hard-coded rounding mode for fp_to_f16; use MXCSR instead. llvm-svn: 259448
* [safestack] Make sure the unsafe stack pointer is popped in all casesAnna Zaks2016-02-024-31/+34
| | | | | | | | | | The unsafe stack pointer is only popped in moveStaticAllocasToUnsafeStack so it won't happen if there are no static allocas. Fixes https://llvm.org/bugs/show_bug.cgi?id=26122 Differential Revision: http://reviews.llvm.org/D16339 llvm-svn: 259447
* [LVI] Fix a latent bug in getValueAtPhilip Reames2016-02-021-0/+8
| | | | | | | | This routine was returning Undefined for most queries. This was utterly wrong. Amusingly, we do not appear to have any callers of this which are actually trying to exploit unreachable code or this would have broken the world. A better approach would be to explicit describe the intersection of facts. That's blocked behind http://reviews.llvm.org/D14476 and I wanted to fix the current bug. llvm-svn: 259446
* Template Type Diffing changeRichard Trieu2016-02-024-38/+34
| | | | | | | When all the arguments of a template are elided, print "A<...>" instead of "A<[2 * ...]>". Also remove comment fragment that means nothing. llvm-svn: 259445
* Always initialize Out<ELFT> members.Rui Ueyama2016-02-021-0/+12
| | | | | | | | Instead of leave unused fields as is, set them to nullptr. Currnetly this is NFC, but if you call writeResults more than once, you should be able to see the difference. llvm-svn: 259444

* Add pointerKind() method to the MachO ArchHandler's. NFC.Pete Cooper2016-02-025-0/+20
| | | | | | | | The ObjCPass is going to need to create pointer sized relocations in the ObjC sections. This method will be used to give us a target independent way of getting the correct kind for the refererence. llvm-svn: 259441
* Add ObjC method list atom type. NFC.Pete Cooper2016-02-013-0/+4

* Add command line option to disable ObjC category merging.Pete Cooper2016-02-013-0/+11
| | | | | | | | | | | This adds the no_objc_category_merging cmdline option which will be used in an upcoming commit to disable the category optimizer. It is on by default in ld64 so we match that here. Test case will come soon with the patch to make use of this option. llvm-svn: 259439

* Move SimpleDefinedAtom::addReference to DefinedAtom.Pete Cooper2016-02-017-29/+45
| | | | | | | | | | | | Most of the other methods to access Reference's were on DefinedAtom so this just keeps them all together. This will be used in a future patch in ObjCPass which needs to add new references. The method is virtual because we may add references to different data structures depending on whether we parsed a macho file or yaml. llvm-svn: 259436

* [LVI] Add select handlingPhilip Reames2016-02-012-0/+118
| | | | | | | | Teach LVI to handle select instructions in the exact same way it handles PHI nodes. This is useful since various parts of the optimizer convert PHI nodes into selects and we don't want these transformations to cause inferior optimization. Note that this patch does nothing to exploit the implied constraint on the inputs represented by the select condition itself. That will be a later patch and is blocked on http://reviews.llvm.org/D14476 llvm-svn: 259429
* Always build a new TypeSourceInfo for function templates with parametersNico Weber2016-02-012-16/+17
| | | | | | | | | | | | | | | | | | | | | RecursiveASTVisitor::TraverseFunctionHelper() traverses a function's ParmVarDecls by going to the function's getTypeSourceInfo if it exists, and `DEF_TRAVERSE_TYPELOC(FunctionProtoType` then goes to the function's ParmVarDecls. For a function template that doesn't have parameters that explicitly depend on the template parameter, we used to be clever and not build a new TypeSourceInfo. That meant that when an instantiation of such a template is visited, its TypeSourceInfo would point to the ParmVarDecls of the template, not of the instantiation, which then confused clients of RecursiveASTVisitor. So don't be clever for function templates that have parameters, even if none of the parameters depend on the type. Fixes PR26257. http://reviews.llvm.org/D16478 llvm-svn: 259428

* MachoFile should default to using subsections_via_symbols.Pete Cooper2016-02-012-1/+29
| | | | | | | | | | | | When we parse a MachoFile, we set a number of members from the parsed file, for example, subsectionsViaSymbols. However, a number of passes, such as ObjCPass, create local copies of MachoFile and don't get the benefit of setting flags and other fields in the parser. Instead we can just give a more sensible default as the parser will definitely get the correct value from the file anyway. llvm-svn: 259426
