Nothing in the llvm language reference indicates the behavior of a global with the 'internal' linkage attribute

Does anybody know if there is a particular reason why MCAsmStreamer doesn't have its own .h file? https://github.com/llvm-mirror/llvm/blob/0e66a5f53c74056f95d178c86531d7d9cfb23da9/lib/MC/MCAsmStreamer.cpp#L41 It seems like it is a good idea to have this class declared as its own module ( its own .cpp and .h files). That would make it easier to inherit from it if there is a need (like in my

Great! Something that is worth pointing out is that the MCStreamer API is intended to directly reflect what is happening in .s files. We basically want one MCStreamer callback to correspond to one

This is a brain-dump of my thoughts on the MCStreamer interface after several days of digging around trying to get a COFF writer working. All fragments should be associated with a symbol. For assembler components, a unnammed "virtual" symbol can be used when there is no explicit label defined. Section assignment should be the responsiblity of the object imlementing the MCStreamer

Hi List I'm running a series of mixed models using lme, and I wonder if there is a way to sort them by AIC prior to testing using anova (lme1,lme2,lme3,....lme7) other than by hand. My current output looks like this. anova (lme.T97NULL.ml,lme.T97FULL.ml,lme.T97NOINT.ml,lme.T972way.ml,lme.T97fc. ml, lme.T97ns.ml, lme.T97min.ml) Model df AIC BIC logLik

Hello everyone, In the file *lib/CodeGen/AsmPrinter/AsmPrinter.cpp*, I would like to obtain an MCInst corresponding to its MachineInstr. Can anyone tell me a way to do that? If that is not possible, then, I would like to know if a given MachineInstr is an *lea *instruction and I would like to know if the symbol involved with this lea instruction is a jump-table. For instance, given a

Hi all, I noticed that the static local variable(internal global in .bc) is not aligned in ARM ELF(use MC(-filetype=obj)). Then I found that the alignment information is lost at: lib/CodeGen/AsmPrinter/AsmPrinter.cpp:316 if (MAI->hasLCOMMDirective()) { // .lcomm _foo, 42 OutStreamer.EmitLocalCommonSymbol(GVSym, Size); return; } MCStreamer::EmitLocalCommonSymbol have
