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 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

We can process this event by adding symbol location info to some AsmParser internal table for example. -- Stepan 08.09.2011, 15:23, "Stepan Dyatkovskiy" <STPWORLD at yandex.ru>: > Hi everybody.

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

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

Hi Nick. Can you help me sort some things out in MergeFucntions pass. While I was working on MergeFunctions pass I got several questions. I hardly tried to find all the answers by myself, but there are still two questions without answer. It is about merging functions itself (not comparing). First question is: Why sometimes we use RAUW and sometimes replaceDirectCallers. Would you help me

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

...nd 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.
