* [opaque pointer types] Cleanup CGBuilder's Create*GEP.James Y Knight2019-02-091-56/+18
| | | | | | | | | | | | | | The various EltSize, Offset, DataLayout, and StructLayout arguments are all computable from the Address's element type and the DataLayout which the CGBuilder already has access to. After having previously asserted that the computed values are the same as those passed in, now remove the redundant arguments from CGBuilder's Create*GEP functions. Differential Revision: https://reviews.llvm.org/D57767 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@353629 91177308-0d34-0410-b5e6-96231b3b80d8
* [opaque pointer types] Cleanup CGBuilder's Create*GEP.James Y Knight2019-02-081-0/+50
| | | | | | | | | | | | | | | | | | | | | | | Some of these functions take some extraneous arguments, e.g. EltSize, Offset, which are computable from the Type and DataLayout. Add some asserts to ensure that the computed values are consistent with the passed-in values, in preparation for eliminating the extraneous arguments. This also asserts that the Type is an Array for the calls named "Array" and a Struct for the calls named "Struct". Then, correct a couple of errors: 1. Using CreateStructGEP on an array type. (this causes the majority of the test differences, as struct GEPs are created with i32 indices, while array GEPs are created with i64 indices) 2. Passing the wrong Offset to CreateStructGEP in TargetInfo.cpp on x86-64 NACL (which uses 32-bit pointers).

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@351636 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | This is similar to the LLVM change https://reviews.llvm.org/D46290. We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

* Change memcpy/memove/memset to have dest and source alignment attributes.Daniel Neilson2018-01-281-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This change is step three in the series of changes to remove alignment argument from memcpy/memmove/memset in favour of alignment attributes. Steps: Step 1) Remove alignment parameter and create alignment parameter attributes for memcpy/memmove/memset. ( rL322965, rC322964, rL322963 ) Step 2) Expand the IRBuilder API to allow creation of memcpy/memmove with differing source and dest alignments. ( rL323597 ) Step 3) Update Clang to use the new IRBuilder API. Step 4) Update Polly to use the new IRBuilder API. Step 5) Update LLVM passes that create memcpy/memmove calls to use the new IRBuilder API, and those that use use MemIntrinsicInst::[get|set]Alignment() to use getDestAlignment() and getSourceAlignment() instead. Step 6) Remove the single-alignment IRBuilder API for memcpy/memmove, and the MemIntrinsicInst::[get|set]Alignment() methods.

* Change memcpy/memset/memmove to have dest and source alignments.Pete Cooper2015-11-181-6/+6
| | | | | | | | | | | | | | | | | | | | | | This is a follow on from a similar LLVM commit: r253511. Note, this was reviewed (and more details are in) http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20151109/312083.html These intrinsics currently have an explicit alignment argument which is required to be a constant integer. It represents the alignment of the source and dest, and so must be the minimum of those. This change allows source and dest to each have their own alignments by using the alignment attribute on their arguments. The alignment argument itself is removed. The only code change to clang is hidden in CGBuilder.h which now passes both dest and source alignment to IRBuilder, instead of taking the minimum of dest and source alignments.

* Compute and preserve alignment more faithfully in IR-generation.John McCall2015-09-081-1/+254
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce an Address type to bundle a pointer value with an alignment. Introduce APIs on CGBuilderTy to work with Address values. Change core APIs on CGF/CGM to traffic in Address where appropriate. Require alignments to be non-zero. Update a ton of code to compute and propagate alignment information. As part of this, I've promoted CGBuiltin's EmitPointerWithAlignment helper function to CGF and made use of it in a number of places in the expression emitter. The end result is that we should now be significantly more correct when performing operations on objects that are locally known to be under-aligned. Since alignment is not reliably tracked in the type system, there are inherent limits to this, but at least we are no longer confused by standard operations like derived-to-base conversions and array-to-pointer decay. I've also fixed a large number of bugs where we were applying the complete-object alignment to a pointer instead of the non-virtual alignment, although most of these were hidden by the very conservative approach we took with member alignment. Also, because IRGen now reliably asserts on zero alignments, we should no longer be subject to an absurd but frustrating recurring bug where an incomplete type would report a zero alignment and then we'd naively do a alignmentAtOffset on it and emit code using an alignment equal to the largest power-of-two factor of the offset. We should also now be emitting much more aggressive alignment attributes in the presence of over-alignment. In particular, field access now uses alignmentAtOffset instead of min. Several times in this patch, I had to change the existing code-generation pattern in order to more effectively use the Address APIs. For the most part, this seems to be a strict improvement, like doing pointer arithmetic with GEPs instead of ptrtoint. That said, I've tried very hard to not change semantics, but it is likely that I've failed in a few places, for which I apologize. ABIArgInfo now always carries the assumed alignment of indirect and indirect byval arguments. In order to cut down on what was already a dauntingly large patch, I changed the code to never set align attributes in the IR on non-byval indirect arguments. That is, we still generate code which assumes that indirect arguments have the given alignment, but we don't express this information to the backend except where it's semantically required (i.e. on byvals). This is likely a minor regression for those targets that did provide this information, but it'll be trivial to add it back in a later patch. I partially punted on applying this work to CGBuiltin. Please do not add more uses of the CreateDefaultAligned{Load,Store} APIs; they will be going away eventually. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@246985 91177308-0d34-0410-b5e6-96231b3b80d8
