* [CFLAA] Split the CFL graph out from CFLSteens. NFC.George Burgess IV2016-07-064-122/+157

* [CFLAA] Split into Anders+Steens analysis.George Burgess IV2016-07-069-73/+198
| | | | | | | | | | | | | | | | | | | | | StratifiedSets (as implemented) is very fast, but its accuracy is also limited. If we take a more aggressive andersens-like approach, we can be way more accurate, but we'll also end up being slower. So, we've decided to split CFLAA into CFLSteensAA and CFLAndersAA. Long-term, we want to end up in a place where CFLSteens is queried first; if it can provide an answer, great (since queries are basically map lookups). Otherwise, we'll fall back to CFLAnders, BasicAA, etc. This patch splits everything out so we can try to do something like that when we get a reasonable CFLAnders implementation. Patch by Jia Chen.

* AArch64: try to fix optimized build failure.Tim Northover2016-07-051-1/+2
| | | | | | | | | I think the Ops filled out by Regex::match contain pointers into the temporary std::string returned by StringRef::upper. Its lifetime is extended by the call to match, but only until the end of that call (not to the uses of Ops later on). llvm-svn: 274586

* AArch64: TableGenerate system instruction operands.Tim Northover2016-07-0510-1959/+1255
| | | | | | | | | | | | | | | | | | | | The way the named arguments for various system instructions are handled at the moment has a few problems: - Large-scale duplication between AArch64BaseInfo.h and AArch64BaseInfo.cpp - That weird Mapping class that I have no idea what I was on when I thought it was a good idea. - Searches are performed linearly through the entire list. - We print absolutely all registers in upper-case, even though some are canonically mixed case (SPSel for example). - The ARM ARM specifies sysregs in terms of 5 fields, but those are relegated to comments in our implementation, with a slightly opaque hex value indicating the canonical encoding LLVM will use. This adds a new TableGen backend to produce efficiently searchable tables, and switches AArch64 over to using that infrastructure. llvm-svn: 274576
* TableGen: promote "code" type from syntactic sugar.Tim Northover2016-07-052-2/+27
| | | | | | | It's being immediately converted to a "string", but being able to tell what type the field was originally can be useful in backends. llvm-svn: 274575
* Revert r259387: "AArch64: Implement missed conditional compare sequences."Balaram Makam2016-07-053-49/+4
| | | | | | | This reverts commit r259387 because it inserts illegal code after legalization in some backends where i64 OR type is illegal for example. llvm-svn: 274573

* ARM: fix `-mlong-calls` for WoASaleem Abdulrasool2016-07-051-1/+1
| | | | | | | | | Not all code-paths set the relocation model to static for Windows. This currently breaks on Windows ARM with `-mlong-calls` when built with clang. Loosen the assertion to what it was previously. We would ideally ensure that all the configuration sets Windows to static relocation model. llvm-svn: 274570
* DAGCombiner: Fold away vector extract of insert with the same indexMatt Arsenault2016-07-051-0/+8
| | | | | | | This only really matters when the index is non-constant since the constant case already gets taken care of by other combines. llvm-svn: 274569
* AArch64: use correct SDValue # when looking for bitfield placement.Tim Northover2016-07-051-2/+3
| | | | | | | | | | The other use really does only care about the SDNode (it checks the opcode against a whitelist), but bitFieldPlacement can be misled if the node produces multiple results. Patch by Ismail Badawi. llvm-svn: 274567
* AMDGPU: Fix folding SGPRs into madak/madmk src0Matt Arsenault2016-07-054-6/+26
| | | | | | | | | | Because of the special immediate operand, the constant bus is already used so SGPRs are never useful. r263212 changed the name of the immediate operand, which broke the verifier check for the restriction. llvm-svn: 274564

* [Thumb] Reapply r272251 with a fix for PR28348 (mk 2)James Molloy2016-07-051-1/+43
| | | | | | | | | | | | | | | | | | | | | | | | | The important thing I was missing was ensuring newly added constants were kept in topological order. Repositioning the node is correct if the constant is newly added (so it has no topological ordering) but wrong if it already existed - positioning it next in the worklist would break the topological ordering. Original commit message: [Thumb] Select a BIC instead of AND if the immediate can be encoded more optimally negated If an immediate is only used in an AND node, it is possible that the immediate can be more optimally materialized when negated. If this is the case, we can negate the immediate and use a BIC instead; int i(int a) { return a & 0xfffffeec; } Used to produce: ldr r1, [CONSTPOOL] ands r0, r1 CONSTPOOL: 0xfffffeec And now produces: movs r1, #255 adds r1, #20 ; Less costly immediate generation bics r0, r1 llvm-svn: 274543

* [PowerPC] - Legalize vector types by widening instead of integer promotionNemanja Ivanovic2016-07-053-1/+100
| | | | | | | | | | | | | | | | | | | This patch corresponds to review: http://reviews.llvm.org/D20443 It changes the legalization strategy for illegal vector types from integer promotion to widening. This only applies for vectors with elements of width that is a multiple of a byte since we have hardware support for vectors with 1, 2, 3, 8 and 16 byte elements. Integer promotion for vectors is quite expensive on PPC due to the sequence of breaking apart the vector, extending the elements and reconstituting the vector. Two of these operations are expensive. This patch causes between minor and major improvements in performance on most benchmarks. There are very few benchmarks whose performance regresses. These regressions can be handled in a subsequent patch with a DAG combine (similar to how this patch handles int -> fp conversions of illegal vector types). llvm-svn: 274535
* Object: support empty UID/GID fieldsSaleem Abdulrasool2016-07-051-2/+8
| | | | | | | | | Normal archives do not have empty UID/GID fields. However, the Microsoft Import library format is a customized archive (it just uses an alternate symbol index format). When the import library is constructed by lib.exe, the UID and GID fields are left empty. Do not abort on such an input. llvm-svn: 274528

* AMDGPU/SI: Remove hack for selecting < 32-bit loads to MUBUF instructionsTom Stellard2016-07-043-15/+15
| | | | | | | | | | | | | | | Summary: The isGlobalLoad() query was returning true for constant address space loads with memory types less than 32-bits, which is wrong. This logic has been replaced with PatFrag in the TableGen files, to provide the same functionality.

* [Thumb] Reapply r272251 with a fix for PR28348James Molloy2016-07-041-1/+40
| | | | | | | | | | | | | | | | | | | | | | | | | We were using DAG->getConstant instead of DAG->getTargetConstant. This meant that we could inadvertently increase the use count of a constant if stars aligned, which it did in this testcase. Increasing the use count of the constant could cause ISel to fall over (because DAGToDAG lowering assumed the constant had only one use!) Original commit message: [Thumb] Select a BIC instead of AND if the immediate can be encoded more optimally negated If an immediate is only used in an AND node, it is possible that the immediate can be more optimally materialized when negated.
