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

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

I used this service several months ago and was very pleased with the response. I have a dataframe with several thousand lines and to each line I need to apply a series of "if else" statements. For each row I need either a value or a blank/NA. Below is the series of if else statements I have been trying without success to integrate into a function such as "apply". if

Hey again) Now I have next code: ; ModuleID = 'sample.lz' @.str1 = internal global [8 x i8] c" world!\00" ; <[8 x i8]*> [#uses=1] @.str2 = internal global [8 x i8] c"hello, \00" ; <[8 x i8]*> [#uses=1] @.str7 = internal global [21 x i8] c"welcome to out hall!\00" ; <[21 x i8]*> [#uses=1] declare i32 @puts(i8*)

but why this code don't work: ; ModuleID = 'sample.lz' @.str1 = internal global [6 x i8] c"world\00" ; <[6 x i8]*> [#uses=1] @.str2 = internal global [7 x i8] c"hello \00" ; <[7 x i8]*> [#uses=1] @.str7 = internal global [7 x i8] c"father\00" ; <[7 x i8]*> [#uses=1] @.str8 = internal global [8 x i8]

Hello everyone, I've added the "S" suffixed versions of ARM and Thumb2 instructions to tablegen. Those are, for example, "movs" or "muls". Of course, some instructions have already had their twins, such as add/adds, and I leaved them untouched. Besides, I propose the codegen optimization based on them, which removes the redundant comparison in patterns like orr

I am trying to understand the hello word assember example. This is my version: %str1 = internal constant [13 x sbyte] c"Hello World\0a\00" declare int %printf(sbyte*, ...) implementation ; Functions: int %main() { %str2 = getelementptr [13 x sbyte]* %str1, long 0, long 0 call int(sbyte*, ...) *%printf(sbyte* %str2) ret int 0 } Why is getelementptr being given two "long

Hi, I have a vector, which contains both strings and numbers, e.g. > foo <- c("str1",1234,"str2",0.9876) I want to know if a distinct element of the vector is a string or a number and took "is.numeric", but > is.numeric(foo[2]) [1] FALSE because R treats the numbers in a mixed vectors as strings: > foo [1] "str1" "1234"

I have some elements in a vector with extraneous information (e.g. file name and sample IDs) that I'd like to strip from every element. For example, I would like "SPI1.S1.str1.P3.sample.tif" "SPI1.S1.STR2.P1.sample.tif" to read "SPI1.S1.str1.P3" "SPI1.S1.STR2.P1". Will someone help me with the syntax in gsub? It needs to be something like

Dear developers: When I am doing basicblock pass, I meet a bug: there is an iterator "I" in a basicblock, and it is not pointing to the first instruction in this basicblock. However, "I--;" will fail by an assertion. The basic block ("I" is pointing to the second instruction) in test.ll: bb: ; preds = %bb1 %1 = call i32 (i8*, ...)* @printf(i8* noalias

Dear all, [system and version information below] I am trying to modify a C function for finding the root of an expression. The function is to be called from R as .Call with input parameters: f: expression for which we will find the root guesses: interval for the solution stol: tolerance rho: environment The original functions I use are: SEXP mkans(double x) { SEXP ans; PROTECT(ans =

It's invalid for the same reason that char *foobar = strcat("foo", "bar"); is invalid in C. Please make sure you understand what you're asking LLVM to do before going any further down this path. A good approach is to write out the correct code in C and then use llvm-gcc (or the demo page at http://llvm.org/demo ) to see what it looks like in LLVM assembly. Nick

Any idea why CHAR(asChar(STRING_ELT( produces NA whereas CHAR(STRING_ELT( gets a pointer to a string? It's generally expected that STRING_ELT should already be a character, but why the coercion does not work? Here is a simple example (consistent over R2.5.1-R2.6 rev 42284, I didn't check earlier versions, but it used to be different in 2.4): install.packages("inline")

Hi, I must say I also was in need of this document but never knew it existed. It seems to be linked from the faq page only. I only read that the first day I came to LLVM. Maybe linking it from the GetElementPtr instruction in LangRef.html would make sense. cheers Eric On Nov 12, 2006, at 8:47 PM, Reid Spencer wrote: > Ram, > > Please read and understand the GetElementPtr FAQ

Hi Str1<-"hai " Str2<-"hru" I want to write these 2 strings in a file separated by newline. How can I get this. Thanks K.Ravichandra [[alternative HTML version deleted]]
