2013-04-26R600: Initialize AMDGPUMachineFunction::ShaderType to ShaderType::COMPUTETom Stellard
We need to intialize this to something and since clang does not set the shader type attribute and clang is used only for compute shaders, initializing it to COMPUTE seems like the best choice.

2013-04-26ARM: Fix encoding of hint instruction for Thumb.Quentin Colombet
"hint" space for Thumb actually overlaps the encoding space of the CPS instruction. In actuality, hints can be defined as CPS instructions where imod and M bits are all nil. Handle decoding of permitted nop-compatible hints (i.e. nop, yield, wfi, wfe, sev) in DecodeT2CPSInstruction. This commit adds a proper diagnostic message for Imm0_4 and updates all tests.

2013-04-26PowerPC: Use RegisterOperand instead of RegisterClass operandsUlrich Weigand
In the default PowerPC assembler syntax, registers are specified simply by number, so they cannot be distinguished from immediate values (without looking at the opcode). This means that the default operand matching logic for the asm parser does not work, and we need to specify custom matchers. Since those can only be specified with RegisterOperand classes and not directly on the RegisterClass, all instructions patterns used by the asm parser need to use a RegisterOperand (instead of a RegisterClass) for all their register operands. This patch adds one RegisterOperand for each RegisterClass, using the same name as the class, just in lower case, and updates all instruction patterns to use RegisterOperand instead of RegisterClass operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180611 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-25Mips assembler: .set reorder supportJack Carter
Mips have delayslots for certain instructions like jumps and branches. These are instructions that follow the branch or jump and are executed before the jump or branch is completed. Early Mips compilers could not cope with delayslots and left them up to the assembler. The assembler would fill the delayslots with the appropriate instruction, usually just a nop to allow correct runtime behavior. The default behavior for this is set with .set reorder. To tell the assembler that you don't want it to mess with the delayslot one used .set noreorder. For backwards compatibility we need to support .set reorder and have it be the default behavior in the assembler. Our support for it is to insert a NOP directly after an instruction with a delayslot when in .set reorder mode.

2013-04-21Legalize vector truncates by parts rather than just splitting.Jim Grosbach
Rather than just splitting the input type and hoping for the best, apply a bit more cleverness. Just splitting the types until the source is legal often leads to an illegal result time, which is then widened and a scalarization step is introduced which leads to truly horrible code generation. With the loop vectorizer, these sorts of operations are much more common, and so it's worth extra effort to do them well. Add a legalization hook for the operands of a TRUNCATE node, which will be encountered after the result type has been legalized, but if the operand type is still illegal. If simple splitting of both types ends up with the result type of each half still being legal, just do that (v16i16 -> v16i8 on ARM, for example). If, however, that would result in an illegal result type (v8i32 -> v8i8 on ARM, for example), we can get more clever with power-two vectors. Specifically, split the input type, but also widen the result element size, then concatenate the halves and truncate again. For example on ARM, To perform a "%res = v8i8 trunc v8i32 %in" we transform to: %inlo = v4i32 extract_subvector %in, 0 %inhi = v4i32 extract_subvector %in, 4 %lo16 = v4i16 trunc v4i32 %inlo %hi16 = v4i16 trunc v4i32 %inhi %in16 = v8i16 concat_vectors v4i16 %lo16, v4i16 %hi16 %res = v8i8 trunc v8i16 %in16 This allows instruction selection to generate three VMOVN instructions instead of a sequences of moves, stores and loads. Update the ARMTargetTransformInfo to take this improved legalization into account. Consider the simplified IR: define <16 x i8> @test1(<16 x i32>* %ap) { %a = load <16 x i32>* %ap %tmp = trunc <16 x i32> %a to <16 x i8> ret <16 x i8> %tmp } define <8 x i8> @test2(<8 x i32>* %ap) { %a = load <8 x i32>* %ap %tmp = trunc <8 x i32> %a to <8 x i8> ret <8 x i8> %tmp } Previously, we would generate the truly hideous: .syntax unified .section __TEXT,__text,regular,pure_instructions .globl _test1 .align 2 _test1: @ @test1 @ BB#0: push {r7} mov r7, sp sub sp, sp, #20 bic sp, sp, #7 add r1, r0, #48 add r2, r0, #32 vld1.64 {d24, d25}, [r0:128] vld1.64 {d16, d17}, [r1:128] vld1.64 {d18, d19}, [r2:128] add r1, r0, #16 vmovn.i32 d22, q8 vld1.64 {d16, d17}, [r1:128] vmovn.i32 d20, q9 vmovn.i32 d18, q12 vmov.u16 r0, d22[3] strb r0, [sp, #15] vmov.u16 r0, d22[2] strb r0, [sp, #14] vmov.u16 r0, d22[1] strb r0, [sp, #13] vmov.u16 r0, d22[0] vmovn.i32 d16, q8 strb r0, [sp, #12] vmov.u16 r0, d20[3] strb r0, [sp, #11] vmov.u16 r0, d20[2] strb r0, [sp, #10] vmov.u16 r0, d20[1] strb r0, [sp, #9] vmov.u16 r0, d20[0] strb r0, [sp, #8] vmov.u16 r0, d18[3] strb r0, [sp, #3] vmov.u16 r0, d18[2] strb r0, [sp, #2] vmov.u16 r0, d18[1] strb r0, [sp, #1] vmov.u16 r0, d18[0] strb r0, [sp] vmov.u16 r0, d16[3] strb r0, [sp, #7] vmov.u16 r0, d16[2] strb r0, [sp, #6] vmov.u16 r0, d16[1] strb r0, [sp, #5] vmov.u16 r0, d16[0] strb r0, [sp, #4] vldmia sp, {d16, d17} vmov r0, r1, d16 vmov r2, r3, d17 mov sp, r7 pop {r7} bx lr .globl _test2 .align 2 _test2: @ @test2 @ BB#0: push {r7} mov r7, sp sub sp, sp, #12 bic sp, sp, #7 vld1.64 {d16, d17}, [r0:128] add r0, r0, #16 vld1.64 {d20, d21}, [r0:128] vmovn.i32 d18, q8 vmov.u16 r0, d18[3] vmovn.i32 d16, q10 strb r0, [sp, #3] vmov.u16 r0, d18[2] strb r0, [sp, #2] vmov.u16 r0, d18[1] strb r0, [sp, #1] vmov.u16 r0, d18[0] strb r0, [sp] vmov.u16 r0, d16[3] strb r0, [sp, #7] vmov.u16 r0, d16[2] strb r0, [sp, #6] vmov.u16 r0, d16[1] strb r0, [sp, #5] vmov.u16 r0, d16[0] strb r0, [sp, #4] ldm sp, {r0, r1} mov sp, r7 pop {r7} bx lr Now, however, we generate the much more straightforward: .syntax unified .section __TEXT,__text,regular,pure_instructions .globl _test1 .align 2 _test1: @ @test1 @ BB#0: add r1, r0, #48 add r2, r0, #32 vld1.64 {d20, d21}, [r0:128] vld1.64 {d16, d17}, [r1:128] add r1, r0, #16 vld1.64 {d18, d19}, [r2:128] vld1.64 {d22, d23}, [r1:128] vmovn.i32 d17, q8 vmovn.i32 d16, q9 vmovn.i32 d18, q10 vmovn.i32 d19, q11 vmovn.i16 d17, q8 vmovn.i16 d16, q9 vmov r0, r1, d16 vmov r2, r3, d17 bx lr .globl _test2 .align 2 _test2: @ @test2 @ BB#0: vld1.64 {d16, d17}, [r0:128] add r0, r0, #16 vld1.64 {d18, d19}, [r0:128] vmovn.i32 d16, q8 vmovn.i32 d17, q9 vmovn.i16 d16, q8 vmov r0, r1, d16 bx lr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179989 91177308-0d34-0410-b5e6-96231b3b80d8

This kind of instruction shouldn't exist, and the extra operand was being confused with the predicate, causing aborts later on. This removes the invalid 0-offset from the instruction being produced. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179956 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-20Remove unused ShouldFoldAtomicFences flag.Tim Northover
I think it's almost impossible to fold atomic fences profitably under LLVM/C++11 semantics. As a result, this is now unused and just cluttering up the target interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179940 91177308-0d34-0410-b5e6-96231b3b80d8
