similar to: [LLVMdev] Beginner question: request guidance on how to trace 'make check' failure in SVN build

Thanks for the helpful pointers. Today morning, I checked out the sources from SVN head revision and found that a fresh build passed all tests. Best regards, Shailesh S.

FAIL: /usr/home/jeffc/llvm/obj/../test/Regression/Transforms/LoopStrengthReduce/dont_insert_redundant_ops.ll: FAIL: /usr/home/jeffc/llvm/obj/../test/Regression/Transforms/LoopStrengthReduce/dont_reduce_bytes.ll:

Hello, This patch aims to improve compile time performance by increasing the SCEV vector size in LoopStrengthReduce. It is observed that the BaseRegs vector size is 4 in most cases, and elements are frequently copied when it is initialized as SmallVector<const SCEV *, 2> BaseRegs. Our benchmark results show that the compilation time performance improved by ~0.5%. Patch by Wan Xiaofei.

The only non-empty output file I can find is ops_after_indvar.ll.out: Instruction does not dominate all uses! %idx = cast int %idx to uint ; <uint> [#uses=1] %tmp. = mul uint %idx, 4 ; <uint> [#uses=1] Instruction does not dominate all uses! %tmp. = mul uint %idx, 4 ; <uint> [#uses=1] %tmp.1 = add uint %P,

The error given: ..\..\..\..\trunk\lib\Transforms\Scalar\LoopStrengthReduce.cpp(1016) : error C2668: 'abs' : ambiguous call to overloaded function f:\Program Files\Microsoft Visual Studio 8\VC\include\math.h(539): could be 'long double abs(long double)' f:\Program Files\Microsoft Visual Studio 8\VC\include\math.h(491): or 'float abs(float)'

This might be hard cases making bad law, but the loop: void f (unsigned short *x, int *l) { int c = *l; int i; for (i = 0; i < c; i++) if (x[i]) x[i]++; } is converted to decrement-and-branch form by LoopStrengthReduce while: void f (unsigned short *x, int *l) { int i; for (i = 0; i < *l; i++) if (x[i]) x[i]++; } isn't.

No error messages with these failures? Can you look into the output files? Reid.

This is related to an issue in loop strength reduction [1] that I've been trying to fix on and off for a while. [1] has a more detailed description of the issue and an example, but briefly put, I want LSR to consider formulae that have "Zext T" as base and/or scale registers, and to appropriately rate such formulae. My first attempt[2] at fixing this was buggy and had to be

Hi, I was building LLVM with gcc 6.1.1 recently and it was spitting out some warnings relating to misleading indention that caught my eye. This wasn't a fresh build so I may have missed some. I've CC'ed the authors of the potentially misleading lines so they can decide what do about the warnings (if anything). I'm wondering if clang-format is making some inappropriate choices

The following failures are consistent on buildbot (and my local box). The Clang one I think it's assuming an Intel box, the other two look like the FileCheck are not good enough. http://lab.llvm.org:8011/builders/clang-native-arm-cortex-a9/builds/4305 Clang :: CodeGen/compound-assign-overflow.c LLVM :: Transforms/LoopStrengthReduce/post-inc-icmpzero.ll LLVM ::

Hello LLVM, This is a proposal for a new pass that improves performance and code size in some nested loop situations. The pass is target independent. >From the description in the file header: This optimization finds loop exit values reevaluated after the loop execution and replaces them by the corresponding exit values if they are available.

Hello, I am quite interested in the project "Instruction Scheduler" under X.org. Please tell me where can I find a detailed idea of the project and how to start it.

Hi, I think a nice project would be to write an application to figure out those latencies automatically maybe even based on envydis. It could generate latency information based on thread count, register usage, instruction/instruction class, hw unit used. Or even tries to figure out what kind of units exist. Like instructions out of a group which are free to issue/execute after instructions out

Hi All, I have a windows 7 as my domU and some windows based drivers are not fully functional (like: touchpad-driver etc ) because they are SMBus based. I was looking at a way to passthrough the SMBus at 00:1f.03 on south bridge ( 00:1f.0), I was debugging at pt-graphics.c and understand that it is detecting the south bridge and passing it through but the other functions for the same dev-id are
