* R600: initial scheduler codeVincent Lejeune2013-03-053-1/+624
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a skeleton for a pre-RA MachineInstr scheduler strategy. Currently it only tries to expose more parallelism for ALU instructions (this also makes the distribution of GPR channels more uniform and increases the chances of ALU instructions to be packed together in a single VLIW group). Also it tries to reduce clause switching by grouping instruction of the same kind (ALU/FETCH/CF) together. Vincent Lejeune: - Support for VLIW4 Slot assignement - Recomputation of ScheduleDAG to get more parallelism opportunities Tom Stellard: - Fix assertion failure when trying to determine an instruction's slot based on its destination register's class - Fix some compiler warnings Vincent Lejeune: [v2] - Remove recomputation of ScheduleDAG (will be provided in a later patch) - Improve estimation of an ALU clause size so that heuristic does not emit cf instructions at the wrong position. - Make schedule heuristic smarter using SUnit Depth - Take constant read limitations into account Vincent Lejeune: [v3] - Fix some uninitialized values in ConstPair - Add asserts to ensure an ALU slot is always populated git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176498 91177308-0d34-0410-b5e6-96231b3b80d8

* The current X86 NOP padding uses one long NOP followed by the remainder inDavid Sehr2013-03-051-12/+12
| | | | | | | | | | | | one-byte NOPs. If the processor actually executes those NOPs, as it sometimes does with aligned bundling, this can have a performance impact. From my micro-benchmarks run on my one machine, a 15-byte NOP followed by twelve one-byte NOPs is about 20% worse than a 15 followed by a 12. This patch changes NOP emission to emit as many 15-byte (the maximum) as possible followed by at most one shorter NOP. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176464 91177308-0d34-0410-b5e6-96231b3b80d8

* X86 cost model: Adjust cost for custom lowered vector multipliesArnold Schwaighofer2013-03-021-5/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This matters for example in following matrix multiply: int **mmult(int rows, int cols, int **m1, int **m2, int **m3) { int i, j, k, val; for (i=0; i<rows; i++) { for (j=0; j<cols; j++) { val = 0; for (k=0; k<cols; k++) { val += m1[i][k] * m2[k][j]; } m3[i][j] = val; } } return(m3); } Taken from the test-suite benchmark Shootout. We estimate the cost of the multiply to be 2 while we generate 9 instructions for it and end up being quite a bit slower than the scalar version (48% on my machine). Also, properly differentiate between avx1 and avx2. On avx-1 we still split the vector into 2 128bits and handle the subvector muls like above with 9 instructions. Only on avx-2 will we have a cost of 9 for v4i64. I changed the test case in test/Transforms/LoopVectorize/X86/avx1.ll to use an add instead of a mul because with a mul we now no longer vectorize. I did verify that the mul would be indeed more expensive when vectorized with 3 kernels: for (i ...) r += a[i] * 3; for (i ...) m1[i] = m1[i] * 3; // This matches the test case in avx1.ll and a matrix multiply. In each case the vectorized version was considerably slower. radar://13304919 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176403 91177308-0d34-0410-b5e6-96231b3b80d8
