similar to: [LLVMdev] Finding the uses of a global variable

Hi, all I try to get the Instructions where one function use the global variable. for (llvm::Module::global_iterator gvar_iter = M.global_begin(); gvar_iter != M.global_end(); gvar_iter++) { llvm::GlobalVariable *gvar = &*gvar_iter; llvm::errs() << "const global var: " << gvar->getName() << "\n"; for (

For LLDB I'm writing a dumb module pass that removes all global variables, by running the following code: bool erased = true; while (erased) { erased = false; for (Module::global_iterator gi = llvm_module.global_begin(), ge = llvm_module.global_end(); gi != ge; ++gi) { GlobalVariable *global_var =

Hi Dong Chen, I realized you are actually executing the IR, right? I am not sure if the things I mentioned apply in that case. Actually, I wrote a optimization pass that modify the IR. It modifies global variables and the final IR is intended to be compiled. A snippet of what I do looks like this: class TestClass : public llvm::ModulePass { public: TestClass() : llvm::ModulePass(TestClass::ID)

Hello everyone, I have the following LLVM IR : @.str = private unnamed_addr constant [3 x i8] c"DS\00", section "llvm.metadata" @llvm.global.annotations = appending global [1 x { i8*, i8*, i8*, i32 }] [{ i8*, i8*, i8*, i32 } { i8* bitcast (i32* @f to i8*), i8* getelementptr inbounds ([3 x i8]* @.str, i32 0, i32 0), i8* getelementptr inbounds ([9 x i8]* @.str1, i32 0, i32 0),

hi Eduardo, thanks for your attention, i checked the iterator, but i didn't see any fucntion can return or modify the main memory address of a global variable inside the module. can you provide some reference code or program can achieve this? thank you very much -- View this message in context:

Dear list: Before going into my problem, R list has been awesome for me ...thank you for the help. I have a simple problem, however I could get a answer to it... #my data myseed <- c(1001:1030) gend <- function(x){ set.seed(x) var <- rep(1:4, c(rep(4, 4))) vary <- rnorm(length(var), 50, 10) mat <- matrix(sample(c(-1,0,1), c(10*length(var)), replace = TRUE), ncol = 10) mydat <-

Talked to Eric Fri and he suggested that this might be the first of several places where we want behavior of LTO compiles to diverge from normal -O2 compiles. So for now I have implemented this such that we pass down -flto to the -cc1 job, and that gets propagated as a code gen option and into the PassManagerBuilder. I have left the current logic translating -flto to the -emit-llvm-bc option,

Thanks Chris, but the method you mentioned is not what I want. Maybe I didn't make it clear. As you said, /runtime/libprofile is runtime library for the following function. llvm_start_func_profiling llvm_start_block_profiling llvm_start_basic_block_tracing llvm_trace_basic_block And those above functions can be inserted into basic block etc for getting profile. However, those

Hi, I have a scalar valued function with several variables. One of the variables is restricted to be non-negative. For example, f(x,y)=sqrt(x)*exp(y), then x should be non-negative. I need the gradient and hessian for some vector (0,y), i.e., I need the gradient and hessian at the boudary of parameter space. The "numderiv" package does not work, even for f(x)=sqrt(x), if you do

P.S. Here's an example of verifier code that can emit multiple messages: bool doFinalization(Module &M) { // Scan through, checking all of the external function's linkage now... for (Module::iterator I = M.begin(), E = M.end(); I != E; ++I) visitGlobalValue(*I);

sure, that's reasonable. I'll make the patch but later this weekend .. bigger fish to fry :) Reid.

Hi, I used split.screen command to creaye 5 screens, 4 screens contain a plot each, the fifth screen is designated to a legend. I am having difficulties setting the dimensions of the screens in a way that would allow me to have the screen dedicated to the legend smaller. I end up with a very awkward aspect at the end: 4 small plots with a big space for the legend. The gend needs to be at

Hi all, First post to the list, I hope you can help or guide me on this task.
