* recommit r172363 & r171325 (reverted in r172756)Nuno Lopes2013-03-023-13/+160
| | | | | | | | This adds minimalistic support for PHI nodes to llvm.objectsize() evaluation fingers crossed so that it does break clang boostrap again.. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176408 91177308-0d34-0410-b5e6-96231b3b80d8

* X86 cost model: Adjust cost for custom lowered vector multipliesArnold Schwaighofer2013-03-023-7/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* PR14448 - prevent the loop vectorizer from vectorizing the same loop twice.Nadav Rotem2013-03-022-0/+93
| | | | | | | | | | | | The LoopVectorizer often runs multiple times on the same function due to inlining. When this happens the loop vectorizer often vectorizes the same loops multiple times, increasing code size and adding unneeded branches. With this patch, the vectorizer during vectorization puts metadata on scalar loops and marks them as 'already vectorized' so that it knows to ignore them when it sees them a second time.

* Rewrite a test to check actual output rather than intermediate implementationEli Bendersky2013-03-011-6/+6
| | | | | | | | | | | | | | | | | | | | detail. The was this test was written, it was relying on an implementation detail (fixups) and hence was very brittle (relying, among other things, on the exact ordering of statistics printed by MC). The test was rewritten to check a more observable output difference. While it doesn't cover 100% of the things the original test covered, it's a good practice to write regression tests this way. If we want to check that internal details and invariants hold, such tests should be expressed as unit tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176377 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | We avoided computing DAG height/depth during Node printing because it shouldn't depend on an otherwise valid DAG. But this has become far too annoying for the common case of a valid DAG where we want to see valid values. If doing the computation on-the-fly turns out to be a problem in practice, then I'll add a mode to the diagnostics to only force it when we're likely to have a valid DAG, otherwise explicitly print INVALID instead of bogus numbers.
