For example, given the following sequence of dag nodes: i32 C = Constant<1> v4i32 V = BUILD_VECTOR C, C, C, C v4i32 Result = SIGN_EXTEND_INREG V, ValueType:v4i1 The SIGN_EXTEND_INREG node can be folded into a build_vector since the vector in input is a BUILD_VECTOR of constants.

* DebugInfo: Remove dead code, DICompositeType::addMember(DIDescriptor D)David Blaikie2013-12-27
| | | | | | | | | | | | | | It's no longer necessary to lazily add members to the DICompositeType member list. Instead any lazy members (special member functions and member template instantiations) are added to the parent late based on their context link, the same way that nested types have always been handled (never being in the member list - just added to the parent DIE lazily based on context). Clang's been updated not to use this function anymore as it improves type unit consistency by never emitting lazy members in type units. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198079 91177308-0d34-0410-b5e6-96231b3b80d8
* Introduce a simple line-by-line iterator type into the Support library.Chandler Carruth2013-12-27
| | | | | | | | | | | | | | | | | | | This is an iterator which you can build around a MemoryBuffer. It will iterate through the non-empty, non-comment lines of the buffer as a forward iterator. It should be small and reasonably fast (although it could be made much faster if anyone cares, I don't really...). This will be used to more simply support the text-based sample profile file format, and is largely based on the original patch by Diego. I've re-worked the style of it and separated it from the work of producing a MemoryBuffer from a file which both simplifies the interface and makes it easier to test. The style of the API follows the C++ standard naming conventions to fit in better with iterators in general, much like the Path and FileSystem interfaces follow standard-based naming conventions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198068 91177308-0d34-0410-b5e6-96231b3b80d8

* Add support to indvars for optimizing sadd.with.overflow.Andrew Trick2013-12-23
| | | | | | | | | | | | | | | | Split sadd.with.overflow into add + sadd.with.overflow to allow analysis and optimization. This should ideally be done after InstCombine, which can perform code motion (eventually indvars should run after all canonical instcombines). We want ISEL to recombine the add and the check, at least on x86. This is currently under an option for reducing live induction variables: -liv-reduce. The next step is reducing liveness of IVs that are live out of the overflow check paths. Once the related optimizations are fully developed, reviewed and tested, I do expect this to become default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197926 91177308-0d34-0410-b5e6-96231b3b80d8

* Add support for positionally-encoded operands to FixedLenDecoderEmitterHal Finkel2013-12-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately, the PowerPC instruction definitions make heavy use of the positional operand encoding heuristic to map operands onto bitfield variables in the instruction definitions. Changing this to use name-based mapping is not trivial, however, because additional infrastructure needs to be designed to handle mapping of complex operands (with multiple suboperands) onto multiple bitfield variables. In the mean time, this adds support for positionally encoded operands to FixedLenDecoderEmitter, so that we can generate a disassembler for the PowerPC backend. To prevent an accidental reliance on this feature, and to prevent an undesirable interaction with existing disassemblers, a backend must opt-in to this support by setting the new decodePositionallyEncodedOperands instruction-set bit to true. When enabled, this iterates the variables that contribute to the instruction encoding, just as the encoder does, and emulates the procedure the encoder uses to map "numbered" operands to variables. The bit range for each variable is also determined as the encoder determines them. This map is then consulted during the decoder-generator's loop over operands to decode, allowing the decoder to understand both position-based and name-based operand-to-variable mappings. As noted in the comment on the decodePositionallyEncodedOperands definition, this support should be removed once it is no longer needed. There should be no change to existing disassemblers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197691 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | This adds support for the .inst directive. This is an ARM specific directive to indicate an instruction encoded as a constant expression.

* [stackprotector] Use analysis from the StackProtector pass for stack layout ↵Josh Magee2013-12-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | in PEI a nd LocalStackSlot passes. This changes the MachineFrameInfo API to use the new SSPLayoutKind information produced by the StackProtector pass (instead of a boolean flag) and updates a few pass dependencies (to preserve the SSP analysis). The stack layout follows the same approach used prior to this change - i.e., only LargeArray stack objects will be placed near the canary and everything else will be laid out normally. After this change, structures containing large arrays will also be placed near the canary - a case previously missed by the old implementation. Out of tree targets will need to update their usage of MachineFrameInfo::CreateStackObject to remove the MayNeedSP argument. The next patch will implement the rules for sspstrong and sspreq. The end goal is to support ssp-strong stack layout rules. WIP.

* Begin adding docs and IR-level support for the inalloca attributeReid Kleckner2013-12-19
| | | | | | | | | | | | | | | | | | | The inalloca attribute is designed to support passing C++ objects by value in the Microsoft C++ ABI. It behaves the same as byval, except that it always implies that the argument is in memory and that the bytes are never copied. This attribute allows the caller to take the address of an outgoing argument's memory and execute arbitrary code to store into it. This patch adds basic IR support, docs, and verification. It does not attempt to implement any lowering or fix any possibly broken transforms. When this patch lands, a complete description of this feature should appear at http://llvm.org/docs/InAlloca.html .

* Add warning capabilities in LLVM.Quentin Colombet2013-12-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reapplies r197438 and fixes the link-time circular dependency between IR and Support. The fix consists in moving the diagnostic support into IR. The patch adds a new LLVMContext::diagnose that can be used to communicate to the front-end, if any, that something of interest happened. The diagnostics are supported by a new abstraction, the DiagnosticInfo class. The base class contains the following information: - The kind of the report: What this is about. - The severity of the report: How bad this is. This patch also adds 2 classes: - DiagnosticInfoInlineAsm: For inline asm reporting. Basically, this diagnostic will be used to switch to the new diagnostic API for LLVMContext::emitError. - DiagnosticStackSize: For stack size reporting. Comes as a replacement of the hard coded warning in PEI. This patch also features dynamic diagnostic identifiers. In other words plugins can use this infrastructure for their own diagnostics (for more details, see getNextAvailablePluginDiagnosticKind).

| | | | | | | | | | | | | | | | | | | | This optional register liveness analysis pass can be enabled with either -enable-stackmap-liveness, -enable-patchpoint-liveness, or both. The pass traverses each basic block in a machine function. For each basic block the instructions are processed in reversed order and if a patchpoint or stackmap instruction is encountered the current live-out register set is encoded as a register mask and attached to the instruction. Later on during stackmap generation the live-out register mask is processed and also emitted as part of the stackmap. This information is optional and intended for optimization purposes only. This will enable a client of the stackmap to reason about the registers it can use and which registers need to be preserved.
