* Make the llvm mangler depend only on DataLayout.Rafael Espindola2014-01-03
| | | | | | | | | | | | | | Before this patch any program that wanted to know the final symbol name of a GlobalValue had to link with Target. This patch implements a compromise solution where the mangler uses DataLayout. This way, any tool that already links with Target (llc, clang) gets the exact behavior as before and new IR files can be mangled without linking with Target. With this patch the mangler is constructed with just a DataLayout and DataLayout is extended to include the information the Mangler needs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198438 91177308-0d34-0410-b5e6-96231b3b80d8

* [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.

If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class.

* SelectionDAG: Teach the legalizer to split SETCC if VSELECT needs splitting too.Juergen Ributzka2013-11-13
| | | | | | | | | | | | | | | | | | | | | | This patch reapplies r193676 with an additional fix for the Hexagon backend. The SystemZ backend has already been fixed by r194148. The Type Legalizer recognizes that VSELECT needs to be split, because the type is to wide for the given target. The same does not always apply to SETCC, because less space is required to encode the result of a comparison. As a result VSELECT is split and SETCC is unrolled into scalar comparisons. This commit fixes the issue by checking for VSELECT-SETCC patterns in the DAG Combiner. If a matching pattern is found, then the result mask of SETCC is promoted to the expected vector mask type for the given target. Now the type legalizer will split both VSELECT and SETCC. This allows the following X86 DAG Combine code to sucessfully detect the MIN/MAX pattern. This fixes PR16695, PR17002, and <rdar://problem/14594431>.

* ISelDAG: spot chain cycles involving MachineNodesTim Northover2013-09-22
| | | | | | | | | | | | | | | | | Previously, the DAGISel function WalkChainUsers was spotting that it had entered already-selected territory by whether a node was a MachineNode (amongst other things). Since it's fairly common practice to insert MachineNodes during ISelLowering, this was not the correct check. Looking around, it seems that other nodes get their NodeId set to -1 upon selection, so this makes sure the same thing happens to all MachineNodes and uses that characteristic to determine whether we should stop looking for a loop during selection. This should fix PR15840. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191165 91177308-0d34-0410-b5e6-96231b3b80d8

* Refactor isInTailCallPosition handlingTim Northover2013-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change came about primarily because of two issues in the existing code. Niether of: define i64 @test1(i64 %val) { %in = trunc i64 %val to i32 tail call i32 @ret32(i32 returned %in) ret i64 %val } define i64 @test2(i64 %val) { tail call i32 @ret32(i32 returned undef) ret i32 42 } should be tail calls, and the function sameNoopInput is responsible. The main problem is that it is completely symmetric in the "tail call" and "ret" value, but in reality different things are allowed on each side. For these cases: 1. Any truncation should lead to a larger value being generated by "tail call" than needed by "ret". 2. Undef should only be allowed as a source for ret, not as a result of the call. Along the way I noticed that a mismatch between what this function treats as a valid truncation and what the backends see can lead to invalid calls as well (see x86-32 test case). This patch refactors the code so that instead of being based primarily on values which it recurses into when necessary, it starts by inspecting the type and considers each fundamental slot that the backend will see in turn. For example, given a pathological function that returned {{}, {{}, i32, {}}, i32} we would consider each "real" i32 in turn, and ask if it passes through unchanged. This is much closer to what the backend sees as a result of ComputeValueVTs. Aside from the bug fixes, this eliminates the recursion that's going on and, I believe, makes the bulk of the code significantly easier to understand. The trade-off is the nasty iterators needed to find the real types inside a returned value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187787 91177308-0d34-0410-b5e6-96231b3b80d8
