[LLVMdev] Get precise line/column debug info from LLVM IR
I am trying to locate instructions in an LLVM Pass by line and column number (reported by an third-party tool) to instrument them. To achieve this, I am compiling my source files with `clang -g -O0 -emit-llvm` and looking for the information in the metadata using this code: const DebugLoc &location = instruction->getDebugLoc(); // location.getLine() // location.getCol()

Strange local variable cv::VideoCapture allocated
Hi I am using clang-6 to compile this C++ code and I see a strange temporary variable allocated at expression address 0x7ff1131536e8. If I change the ternary operator at line 483 to an if-else, the temporary is not allocated. Thanks Variables: ========= FFMPEGVideoCapture ffmpeg_video_capture_; cv::VideoCapture opencv_video_capture_; Function: ======== bool

[LLVMdev] Libclang get class name from DeclRefExpr
Hi guys, I am trying to extract the class name of a parameter to a method call in objective-C. The code I am parsing is: - (void)testAddConcreteDataModel:(DFDemoDataModelOne*)helpmeh { [self.dataModels addObject:helpmeh]; } And the result I need is the type of class of helpmeh, which is "DFDemoDataModelOne". So far I have the following code, which outputs:

Looking for help with an ast matcher
Hi Piotr, I think I found a working matcher: match ifStmt(hasCondition(implicitCastExpr(hasImplicitDestinationType(isInteger()), has(cxxMemberCallExpr(callee(cxxMethodDecl(hasName("compare"))), hasArgument(0, declRefExpr().bind("str2")), callee(memberExpr(has(declRefExpr().bind("str1"))))))))).bind("case1") This one bind to both str1 and str2 in

Looking for help with an ast matcher
Hi Piotr, Thanks. Yeah, it seemed a little weird, but it was what got me closest. I found out that the matcher I supplied here was working for clang-query 3.8.1. I'm working on a clang-tidy module for 4.0.0 - it's not working there. Could you elaborate on the "onImplicitObjectArgument"? There is no document on it on the clang page. So I wouldn't know how it works or what it

Difference in S.E. gee/yags and geeglm(/geese)
Hi A quick question. Standard errors reported by gee/yags differs from the ones in geeglm (geepack). require(gee) require(geepack) require(yags) mm <- gee(breaks ~ tension, id=wool, data=warpbreaks, corstr="exchangeable") mm2 <- geeglm(breaks ~ tension, id=wool, data=warpbreaks, corstr="exchangeable", std.err = "san.se") mm3 <- yags(breaks ~

detecting the source of memory consumption (example provided)
I have read in a file (call it myData). The actual file is about 3000x30,000 columns and object.size() says myData takes: > 737910472/(1024^2) [1] 703.7263 Unfortunately, my program ends up using 40GB as indicated by maxvmem on Unix, which causes my department's cluster to stop working. Perhaps, I have some copying going on that I cannot find. I have created an example below that mimics
