* R600/SI: Initialize M0 and emit S_WQM_B64 whenever DS instructions are usedTom Stellard2014-02-10
| | | | | | | | | | | DS instructions that access local memory can only uses addresses that are less than or equal to the value of M0. When M0 is uninitialized, then we experience undefined behavior. This patch also changes the behavior to emit S_WQM_B64 on pixel shaders no matter what kind of DS instruction is used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201097 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM: use natural LLVM IR for vshll instructionsTim Northover2014-02-10
| | | | | | | | Similarly to the vshrn instructions, these are simple zext/sext + trunc operations. Using normal LLVM IR should allow for better code, and more sharing with the AArch64 backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201093 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM: r12 is callee-saved for interrupt handlersOliver Stannard2014-02-10
| | | | | | | | | For A- and R-class processors, r12 is not normally callee-saved, but is for interrupt handlers. See AAPCS, 5.3.1.1, "Use of IP by the linker". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201089 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM: use LLVM IR to represent the vshrn operationTim Northover2014-02-10
| | | | | | | | | | vshrn is just the combination of a right shift and a truncate (and the limits on the immediate value actually mean the signedness of the shift doesn't matter). Using that representation allows us to get rid of an ARM-specific intrinsic, share more code with AArch64 and hopefully get better code out of the mid-end optimisers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201085 91177308-0d34-0410-b5e6-96231b3b80d8

* LLVM-1163: AAPCS-VFP violation when CPRC allocated to stackOliver Stannard2014-02-07
| | | | | | | | | | | | | | According to the AAPCS, when a CPRC is allocated to the stack, all other VFP registers should be marked as unavailable. I have also modified the rules for allocating non-CPRCs to the stack, to make it more explicit that all GPRs must be made unavailable. I cannot think of a case where the old version would produce incorrect answers, so there is no test for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200970 91177308-0d34-0410-b5e6-96231b3b80d8

Basically the idea is to transform code like this: %idx = add nsw i32 %a, 1 %sextidx = sext i32 %idx to i64 %gep = gep i8* %myArray, i64 %sextidx load i8* %gep Into: %sexta = sext i32 %a to i64 %idx = add nsw i64 %sexta, 1 %gep = gep i8* %myArray, i64 %idx load i8* %gep That way the computation can be folded into the addressing mode. This transformation is done as part of the addressing mode matcher. If the matching fails (not profitable, addressing mode not legal, etc.), the matcher will revert the related promotions. <rdar://problem/15519855> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200947 91177308-0d34-0410-b5e6-96231b3b80d8

* [RegAlloc] Add a last chance recoloring mechanism when everything else failed toQuentin Colombet2014-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | find a register. The idea is to choose a color for the variable that cannot be allocated and recolor its interferences around. Unlike the current register allocation scheme, it is allowed to change the color of an already assigned (but maybe not splittable or spillable) live interval while propagating this change to its neighbors. In other word, there are two things that may help finding an available color: - Already assigned variables (RS_Done) can be recolored to different color. - The recoloring allows to catch solutions that needs to touch more that just the neighbors of the current allocated variable. E.g., vA can use {R1, R2 } vB can use { R2, R3} vC can use {R1 } Where vA, vB, and vC cannot be split anymore (they are reloads for instance) and they all interfere. vA is assigned R1 vB is assigned R2 vC tries to evict vA but vA is already done. => Regular register allocation heuristic fails. Last chance recoloring kicks in: vC does as if vA was evicted => vC uses R1. vC is marked as fixed. vA needs to find a color. None are available. vA cannot evict vC: vC is a fixed virtual register now. vA does as if vB was evicted => vA uses R2. vB needs to find a color. R3 is available. Recoloring => vC = R1, vA = R2, vB = R3. <rdar://problem/15947839> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200883 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | inline assembly This patch fixes the ldr-pseudo implementation to work when used in inline assembly. The fix is to move arm assembler constant pools from the ARMAsmParser class to the ARMTargetStreamer class. Previously we kept the assembler generated constant pools in the ARMAsmParser object. This does not work for inline assembly because a new parser object is created for each blob of inline assembly. This patch moves the constant pools to the ARMTargetStreamer class so that the constant pool will remain alive for the entire code generation process. An ARMTargetStreamer class is now required for the arm backend. There was no existing implementation for MachO, only Asm and ELF. Instead of creating an empty MachO subclass, we decided to make the ARMTargetStreamer a non-abstract class and provide default (llvm_unreachable) implementations for the non constant-pool related methods.

* AArch64 & ARM: refactor crypto intrinsics to take scalarsTim Northover2014-02-03
| | | | | | | | | | | | Some of the SHA instructions take a scalar i32 as one argument (largely because they work on 160-bit hash fragments). This wasn't reflected in the IR previously, with ARM and AArch64 choosing different types (<4 x i32> and <1 x i32> respectively) which was ugly.
