* Fix Clang-tidy modernize-use-nullptr and modernize-use-override warnings; ↵Eugene Zelenko2016-01-261-14/+10

* Sort intrinsics by LLVM intrinsic name, rather than tablegen def nameReid Kleckner2016-01-261-0/+4
| | | | | | | | | | | | Step one towards using a simple binary search to lookup intrinsic IDs instead of our crazy table generated switch+memcmp+startswith code that makes Function.cpp take about a minute to compile. See PR24785 and PR11951 for why we should do this. The X86 backend contains tables that need to be sorted on intrinsic ID, so reorder those. llvm-svn: 258757
* [TableGen] Fix sort order of asm operand classesOliver Stannard2016-01-251-20/+85
| | | | | | | | | | | | | | | | | | | | | | This is a fix for https://llvm.org/bugs/show_bug.cgi?id=22796. The previous implementation of ClassInfo::operator< allowed cycles of classes such that x < y < z < x, meaning that a list of them cannot be correctly sorted, and the sort order could differ with different standard libraries. The original implementation sorted classes by ValueName if they were otherwise equal. This isn't strictly necessary, but some backends seem to accidentally rely on it. If I reverse this comparison I get 8 test failures spread across the AArch64, Mips and X86 backends, so I have left it in until those backends can be fixed. There was one case in the X86 backend where the observable behaviour of the assembler is changed by this patch. This was because some of the memory asm operands were not marked as children of X86MemAsmOperand. Differential Revision: http://reviews.llvm.org/D16141 llvm-svn: 258677
* [TableGen] In AsmWriterEmitter unique command search, rather than storing a ↵Craig Topper2016-01-241-43/+32

* [GlobalISel] Add a generic machine opcode for ADD.Quentin Colombet2016-01-201-0/+5
| | | | | | | | | | | The selection process being split into separate passes, we need generic opcodes to translate the LLVM IR to target independent code. This patch adds an opcode for addition: G_ADD. Differential Revision: http://reviews.llvm.org/D15472 llvm-svn: 258333
* [TableGen] Merge the SuperClass Record and SMRange vector into a single ↵Craig Topper2016-01-181-4/+3

* [TableGen] Allow asm writer to use up to 3 OpInfo tables instead of 2. This ↵Craig Topper2016-01-111-30/+32
| | | | | | | | allows x86 to use 56 total bits made up of a 32-bit, 16-bit, and 8-bit table. Previously we were using 64 total bits. This saves 14K from the x86 table size. And saves space on other targets as well. llvm-svn: 257315

* [TableGen] Modify the AsmMatcherEmitter to only apply the table growth from ↵Craig Topper2015-12-311-63/+110
| | | | | | | | | | | | | | r252440 to the Hexagon target. This restores the previous behavior of not including the mnemonic in the classes table for every target that starts instruction lines with the mnemonic. Not only did the table size increase by 1 entry, but the class enum increased in size which caused every class in the array to increase in size. It also grew the size of the function that parsers tokens into classes by a substantial amount. This adds a new HasMnemonicFirst flag to all AsmParsers. It's set to 1 by default and Hexagon target overrides it to 0. For the X86 target alone this recovers 324KB of size on the llvm-mc executable. I believe the current state is still a bad design choice for the Hexagon target as it causes most of the parsing to do a linear search through the entire match table to comparing operands against every instruction until it finds one that works. At least for the other targets we do a binary search based on mnemonic over which to do the linear scan. llvm-svn: 256669

* Provide a way to specify inliner's attribute compatibility and merging.Akira Hatanaka2015-12-221-1/+98
| | | | | | | | | | | | | | | | | | | | | This reapplies r256277 with two changes: - In emitFnAttrCompatCheck, change FuncName's type to std::string to fix a use-after-free bug. - Remove an unnecessary install-local target in lib/IR/Makefile. Original commit message for r252949: Provide a way to specify inliner's attribute compatibility and merging rules using table-gen. NFC. This commit adds new classes CompatRule and MergeRule to Attributes.td, which are used to generate code to check attribute compatibility and merge attributes of the caller and callee. rdar://problem/19836465 llvm-svn: 256304

| | | | | | | | For targets to add their own operand types as needed, as advertised in Operand's comment, they need to be able to specify an alternate namespace for OperandType names too. This matches the RegisterOperand class. llvm-svn: 256299

| | | | | | | | | | | | | | | | | | | | | | Part 1 was submitted in http://reviews.llvm.org/D15134. Changes in this part: * X86RegisterInfo.td, X86RecognizableInstr.cpp: Add FR128 register class. * X86CallingConv.td: Pass f128 values in XMM registers or on stack. * X86InstrCompiler.td, X86InstrInfo.td, X86InstrSSE.td: Add instruction selection patterns for f128. * X86ISelLowering.cpp: When target has MMX registers, configure MVT::f128 in FR128RegClass, with TypeSoftenFloat action, and custom actions for some opcodes. Add missed cases of MVT::f128 in places that handle f32, f64, or vector types. Add TODO comment to support f128 type in inline assembly code. * SelectionDAGBuilder.cpp: Fix infinite loop when f128 type can have VT == TLI.getTypeToTransformTo(Ctx, VT). * Add unit tests for x86-64 fp128 type.
