Now I see, that its to so trivial as I thought before. There are a lots of parser extensions that creates the symbols. And in each place we need insert add its location info. I also found that MCContext has several create symbols methods, but all these methods uses CreateSymbol private method. So I see two possible ways here: 1. To aggregate all GetOrCreate-like symbol methods inside the

I just want to update test/Transforms/LowerSwitch/feature.ll that already uses grep. It uses grep + count, probably due to shorter construction. -Stepan.

Hm... tests were corrected themselves. No svn updates was made. 0. I turned on my laptop and boot Ubuntu 11.04. 1. I run ../llvm/configure in clean folder. 2. make 3. make check-lit 4. Tests was looped at 61%. Eclipse doesn't want to debug it too. It crashes at the start of debug session. I reboot my computer again, and all work well now. Probably some specific bios + OS + (specific cpu

Hi David, After merging we always remove body of "G" (function we want to merge with "existing" one). In case with "writeThunk" we could add such info for "G", but it would be just a single string: reference to first string of "G". Ideal way here, is to merge debug information itself, and provide "F" with information for "G"

Hi Stephan, I've been thinking about this a bit and have some more specific ideas, I'll write up a design and maybe implement it over the next few days. -Chris On Jan 21, 2012, at 11:50 PM, Stepan Dyatkovskiy <STPWORLD at narod.ru> wrote: > Hi Chris.

Hi everybody. I found that there are some problems with symbol location in AsmParser. 1. We need to know where symbol was declared. 2. We need to know where symbol was defined first time. There are two ways: 1. Add helper table to the parser with additional symbol info. But it takes additional memory consumption. 2. Add user tag (void*) for MCSymbol object. As I understood MCSymbol can live

Guys, you can exclude me (dyatkovskiy) from this list, since I reverted my changes in r162354. -Stepan. llvm.buildmaster at lab.llvm.org wrote: > The Buildbot has detected a new failure on builder clang-native-mingw64-win7 while building cfe. > Full details are available at: > http://lab.llvm.org:8011/builders/clang-native-mingw64-win7/builds/876 > > Buildbot URL:

Hi. I just want to know does anyone has the same problem or not. After running "make check-lit" tests are stopped at 61th percent (Linker tests). Each time it stops on different tests. Thanks. -- Regards, Stepan

Hi Chris. The main question is how to implement ConstantAggregateXXXXX::getOperand?

How many times will a typical client call getOperand on your helper when it wraps a 10,000 element ConstantAggregateZero? With CAZ the client is force to think about this case, and often handles it much much more efficiently. CAZ is a time optimization as well as a space optimization. -Chris On Jan 21, 2012, at 12:03 AM, Stepan Dyatkovskiy <STPWORLD at narod.ru> wrote: > Hi Chris.

Hi Stepan, This looks interesting! Some high-level comments: - Please post the patch untarred next time. Also, I'm not sure if it's typical to provide supporting documents in .doc format; while many of us probably have access to Word, a more portable and email-friendly format (like text, markdown or rst) is probably better. - Have you profiled this? What's the speedup? I

Yes. It doesn't works properly. I also read the your discussion in bug 1784: http://llvm.org/bugs/show_bug.cgi?id=1784 I found that know Type and Vector Lagalization and in DAGCombining implicitly assumed that element size of MemoryVT is multiply of 8 bits. Thats the main reason why v2i5 works improperly with load/store. But I can't determine exactly what MemoryVT means... -Stepan.

Yep check out PR1324. Doing something like this would be a great improvement. -Chris On Jan 21, 2012, at 9:42 AM, Duncan Sands <baldrick at free.fr> wrote: > Hi Anton, in a solution without CAZ, isNullValue can just return true when it > sees the special "this ConstantArray is all zero" flag.

Hi all, Previous patch has been split onto series of small changes. On each stage (after each patch) MergeFunctions pass is compilable and stable. Please find patches in attachment for review. To apply all patches at once, use "apply-patches.sh" script as follows: 0. Place "apply-patches.sh" in same directory with patches. 1. cd <llvm-sources-dir> 2. "bash

Probably, I misunderstood MemoryVT purpose? Should it be a type that equal to original vector type (e.g. v2i5). Or it is a type of memory area for this vector (e.g. v2i8) ? -Stepan.

Hi Chris. There is no zero arrays created. Probably this patch is not optimal and I'll reworked it today. But the main idea is keep a single zero-item when ConstantAggregateZero was wrapped and return this zero item as result of getOperand call. Note that wrapper has no parent classes, it has very local and short lifetime (method body), it exists outside the LLVMContext and needed for
