Saves about 58KB. These LinkAll{CodeGen/AsmWriter}Components.h headers are only #included by LLC/LLI. We could create our own version of these if we want to create our own version of LLC, but that could make it harder to notice when the header changes.

2013-03-04Bypass Slow DividesPreston Gurd
* Only apply divide bypass optimization when not optimizing for size. * Fixed bug caused by constant for 0 value of type Int32, used dividend type to generate the constant instead. * For atom x86-64 apply the divide bypass to use 16-bit divides instead of 64-bit divides when operand values are small enough. * Added lit tests for 64-bit divide bypass.

2013-03-02X86 cost model: Adjust cost for custom lowered vector multipliesArnold Schwaighofer
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

2013-03-02PR14448 - prevent the loop vectorizer from vectorizing the same loop twice.Nadav Rotem
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.

2013-03-01In llvm::MemoryBuffer::getFile() remove an unnecessary stat call check.Argyrios Kyrtzidis
The sys::fs::is_directory() check is unnecessary because, if the filename is a directory, the function will fail anyway with the same error code returned.

2013-03-01Rewrite a test to check actual output rather than intermediate implementationEli Bendersky
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
