I have a question. If the size of long is 8 on your x64 platform. Because the size of long is so different on different platform, sad it is. 2009/9/23, David Greene <dag at cray.com>: > How are bitfields handled in StructLayout?

Hello, Can I define a named type ? %rt = {%rt} llvm-as can parse this definition without errors. JIT executes '%0 = alloca %rt' as allocating a memory with size 0. Because the llvm::TargetData::getTypeAllocSize accually returns 0 in this case. The function that calculates %rt's size is by the TargetData::getStructLayout, which calculates the a layout of %rt. It can only returns 0

Hi all, hope someone can help me out with this. Background Introduction I have a data set consisting of data collected from a questionnaire that I wish to validate. I have chosen to use confirmatory factor analysis to analyse this data set. Instrument The instrument consists of 11 subscales. There is a total of 68 items in the 11 subscales. Each item is scored on an integer scale between 1 to 4.

I went ahead and implemented the allocation based on the maximum size of all structs seen so far... The problem is, the TargetData object from ExecutionEngine gives me a size of 12 for a struct containing a pointer and an i64 (on a 32-bit machine). However, the generated code seems to assume an alignment of 8, and tries to read the i64 value at offset 8, which obviously reads an invalid value.

Please review this patch for PR3510 (and <rdar://problem/6564697>). The bug is a failure to handle a "hole" inside an initialized structure, where the hole may be induced by a designated initializer or by alignment: http://llvm.org/bugs/show_bug.cgi?id=3510 The original code was greatly simplified by using FieldNo to index the LLVM fields and the initializer in

Hi, Can any llvm pass change simple return branch into select/return pair? For example: define i10 @mod_N(i10 zeroext %a) zeroext { entry: %tmp2 = icmp ugt i10 %a, -400 ; <i1> [#uses=1] br i1 %tmp2, label %cond_true, label %return cond_true: ; preds = %entry %tmp5 = add i10 %a, 400 ; <i10> [#uses=1] ret i10 %tmp5 return: ; preds = %entry ret

LLVMers, I have a const StructType *StTy where I call TargetData->getStructLayout(const_cast<StructType*>(StTy))->getSizeInBits() but it continues to return 64 regardless of the actual size of the struct? I want the size of the structure in bits, including alignment padding for offset calculations, is this not the right function call? Thanks. -------------- next part

Hello, I would like to access my data frame without one variable. E.g.: > colnames(x) [1] "Besch" "Ang.m" "Arb.m" "i10" "Umsatz" "arbstd" I can try x[,-1], but this variable must be called by it??s name. x[,-"Besch"] x[,!"Besch"] attach(x) x[-Besch] ... ... does not work. I could not found a solution of

Is there a way to get the sizeof a type? Say I've created a struct type without any explicit attribtues, and I want to call malloc() to allocate space for it. Can I get the size as an llvm::Constant* (or other llvm::Value*) given an llvm::StructType* or other llvm::Type*? TIA, -- Rick

Hi all, We're hitting some walls here when generating the correct structure layout for specific C++ ABI requirements, and I was wondering how much StructLayout could help. For instance, the ABI has some complicated rules on the size of derived classes (http://www.codesourcery.com/public/cxx-abi/abi.html#class-types) and LLVM struct type cannot reflect that in full. Example: // CHECK:

Hello, What is your opinion on Ubuntu. I´ve encountered a couple hurdles here. The Keyboard: I have to hit the quote button twice to get a quote or apostrophe! I tried adjusting keyboard settings but nothing changed. And the RKWard GUI won´t recognize quotes from my machines even though they show up on the RKWard text editor. On the other hand, RKWard will quoted material whien I copy and

If you have commit access, please just directly change the document. The release is planned to go out in about 24 hours from now! Thanks! -Chris
