* [CodeGen] Add lrint/llrint builtinsAdhemerval Zanella2019-05-281-0/+2
| | | | | | | | | | | | | | | | | This patch add the ISD::LRINT and ISD::LLRINT along with new intrinsics. The changes are straightforward as for other floating-point rounding functions, with just some adjustments required to handle the return value being an interger. The idea is to optimize lrint/llrint generation for AArch64 in a subsequent patch. Current semantic is just route it to libm symbol.

* [Intrinsic] Signed Fixed Point Saturation Multiplication IntrinsicLeonard Chan2019-05-211-0/+2
| | | | | | | | | | | | | | Add an intrinsic that takes 2 signed integers with the scale of them provided as the third argument and performs fixed point multiplication on them. The result is saturated and clamped between the largest and smallest representable values of the first 2 operands. This is a part of implementing fixed point arithmetic in clang where some of the more complex operations will be implemented as intrinsics.

* Implementation of asm-goto support in LLVMCraig Topper2019-02-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This patch accompanies the RFC posted here: http://lists.llvm.org/pipermail/llvm-dev/2018-October/127239.html This patch adds a new CallBr IR instruction to support asm-goto inline assembly like gcc as used by the linux kernel. This instruction is both a call instruction and a terminator instruction with multiple successors. Only inline assembly usage is supported today. This also adds a new INLINEASM_BR opcode to SelectionDAG and MachineIR to represent an INLINEASM block that is also considered a terminator instruction. There will likely be more bug fixes and optimizations to follow this, but we felt it had reached a point where we would like to switch to an incremental development model.

* 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. llvm-svn: 351636
* [SelectionDAG] Updates for -dag-dump-verboseBjorn Pettersson2019-01-181-34/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch makes some changes related to -dag-dump-verbose. Main use case has been when debugging how SelectionDAG is dealing with debug info (SDDbgValue nodes). 1) We now print the number of DbgValues that are mapped to each SDNode. 2) Removed duplicated printing of DebugLoc (nowadays DebugLoc is printed also when not using -dag-dump-verbose). 3) Renamed SDDbgValue::dump to SDDbgValue::print, and added a new SDDbgValue::dump that will start a new line after calling print. 4) SDDbgValue::print now prints "Order", and it also prints some additional information when kind is CONST/FRAMEIX/VREG. 5) SelectionDAG::dump() now dumps all SDDbgValue nodes after the list of SDNodes (both "regular" and "ByVal" SDDbgValue:s). Invalidated nodes are not printed. 6) Prohibit inline printing of SDNode operands that has SDDbgValue nodes associated to them.

* [DAGCombiner] try to convert pow(x, 1/3) to cbrt(x)Sanjay Patel2018-09-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is a follow-up suggested in D51630 and originally proposed as an IR transform in D49040. Copying the motivational statement by @evandro from that patch: "This transformation helps some benchmarks in SPEC CPU2000 and CPU2006, such as 188.ammp, 447.dealII, 453.povray, and especially 300.twolf, as well as some proprietary benchmarks. Otherwise, no regressions on x86-64 or A64." I'm proposing to add only the minimum support for a DAG node here. Since we don't have an LLVM IR intrinsic for cbrt, and there are no other DAG ways to create a FCBRT node yet, I don't think we need to worry about DAG builder, legalization, a strict variant, etc. We should be able to expand as needed when adding more functionality/transforms. For reference, these are transform suggestions currently listed in SimplifyLibCalls.cpp: // * cbrt(expN(X)) -> expN(x/3) // * cbrt(sqrt(x)) -> pow(x,1/6) // * cbrt(cbrt(x)) -> pow(x,1/9) Also, given that we bail out on long double for now, there should not be any logical differences between platforms (unless there's some platform out there that has pow() but not cbrt()).

| | | | | | | | | | | | CodeGen layer. Currently EVT is in the IR layer only because of Function.cpp needing a very small piece of the functionality of EVT::getEVTString(). The rest of EVT is used in codegen making CodeGen a better place for it. The previous code converted a Type* to EVT and then called getEVTString. This was only expected to handle the primitive types from Type*. Since there only a few primitive types, we can just print them as strings directly.

* [AArch64] Improve v8.1-A code-gen for atomic load-andOliver Stannard2018-02-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Armv8.1-A added an atomic load-clear instruction (which performs bitwise and with the complement of it's operand), but not a load-and instruction. Our current code-generation for atomic load-and always inserts an MVN instruction to invert its argument, even if it could be folded into a constant or another instruction. This adds lowering early in selection DAG to convert a load-and operation into an xor with -1 and a load-clear, allowing the normal DAG optimisations to work on it. To do this, I've had to add a new ISD opcode, ATOMIC_LOAD_CLR. I don't see any easy way to do this with an AArch64-specific ISD node, because the code-generation for atomic operations assumes the SDNodes are of type AtomicSDNode. I've left the old tablegen patterns in because they are still needed for global isel. Differential revision: https://reviews.llvm.org/D42478 llvm-svn: 324908

* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787
