I use recordPlot() to save plots to disk that I render later to a variety of formats. This works fine for base R plots and ggplot2 plots, and also used to work for lattice plots. However somewhere in version 2.14 things stopped working for lattice plots. Here is an example: library(lattice); histogram(rnorm(100)); x <- recordPlot(); saveRDS(x, "myplot.rds"); y <-

I need help. I can't get it to work. I'm crying here, really, I'm balling my eyes out. Is there any way for a beginner to get support with using LLVM? All my queries are just ignored or disregarded on this mailing list. Why isn't there an llvm mailing list for novices? This is the only thing that can get my programming language, to be operation in a reasonable amount of time,

Hi, the dovecot antispam plugin crahses here on a nullpointer dereference in antispam_copy() at mailbox.c The crash tracks back to a call of antispam_classify_copy(asms->box_class, asmb->box_class) At that point in time asmb is set to 0x0, causing the process to crash with SIGSEGV. Regards, Thomas GDB output: Program received signal SIGSEGV, Segmentation fault. antispam_copy

The advantages: 1. A pointer to the struct offset can be converted to a pointer without any cost. 2. A nullpointer to a stretchy buffer can be treated as a zero length array. Consequently no actual struct allocation is needed to represent a zero length array. 3. A reference to the array is the same size as to a pointer. 4. It can be converted to and back from an pointer without losing any

hello, i use rsync as a major backend for our automatic debian GNU/linux workstation synchronisation project at the Free University of Berlin / Computer Science. my concept is, that rsync gets the class, group and machine-specific root-trees as argument, and it's up to him to find and automaticaly remove duplicated files on the basis of the priority (which is actually the argument list).

Hi, I am using Eclipse to edit the files, and I used it to debug with gdb as well (but I went back to gdb on the command line, Eclipse GDB UI is just too slow and buggy for me ..). You need to exclude the clang preprocessor/.. stress tests from the sources, otherwise the indexer will freeze Eclipse. You should also remove some autogenerated CMake project subdirectories, otherwise your files

LLVMers, On the way to resolving bug 122, I am committing my SymbolTable rewrite. If you are working on anything that uses the SymbolTable, I suggest you read the documentation in include/llvm/SymbolTable.h. The changes I've committed reduce the use of Type::TypeTy. This static member will go away in the future, so please do not propagate new code that uses it. There is no reason to use it

Yes, we’re actually viewing the struct at an offset. So basically it’s a struct like this: typedef struct { uint32_t size; uint32_t capacity; int array[0]; } Foo; The whole thing is malloc:ed with extra bytes at the end, and capacity is set to that same number of extra bytes. What’s then passed around is actually the int pointer at an offset: &(foo->array) Using the that pointer

Hi, Thanks both of you for the help. I just missed that Create function had many optional arguments... sorry for that. However my problem wasn't coming from here (IRBuilder CreateCall function still return a pointer to CallInst so I just added 2 times the call?). I didn't wanted to detail the all issue previously because I knew I had a problem with my syntax. So here's my problem: I
