[LLVMdev] JIT'ing 2 functions with inter-dependencies
I am having problems JIT'ing 2 functions where one of them calls the other. (I am using the old JIT interface). Here is the setup: define void @func1() { entrypoint: call void @func2(void) ret void } define void @func2(void) { entrypoint: ret void } (I omit the arguments and function bodies for simplicity.) It's 'func1' that would be called from host code,

Generalizing call to function
Hello guys, I would like to ask for help to understand what is going on in "func2". My plan is to generalize "func1", so that are expected same results in "func2" as in "func1". Executing "func1" returns... 0.25 with absolute error < 8.4e-05 But for "func2" I get... Error in dpois(1, 0.1, 23.3065168689948, 0.000429064542600244,

[LLVMdev] How to split module?
Hi, all. My question is about how to split one module into N modules(N >= 2)? For example, given the following code: #src.c# int main() { //......// func1(); func2(); //......// return 0; } void func1() { //......// } void func2() { //......// } func1() has no dependence with func2(), so they can perform parallel execution. And I have to split src.c into src1.c

[LLVMdev] Integer ID for LLVM::Instruction*?

reusing external functions across libs
Hi, I am searching for a way to solve the following problem: I want to use an external function, defined in a dyn.load()ed shared object, in another dyn.load()ed shared object. Currently I have to take the sources (Fortran) from one libraries src/ directory and copy them into the src/ dir of the other library, resulting in two copies of this function. This is bad for maintanance and maybe also

Questions for package ts prediction
Dear helpers, I am trying to write a function to return prediction values using package ts. I have written three different versions since I am not sure what's wrong with my func2. func and func1 return the same results.But func1 and func2 don't. In particular, the only difference between "func1" and "func2" is the function variable name being y and data, respectively.

Integrate with an indicator function
Hi all, I have some some problem with regard to finding the integral of a function containing an indicator function. please see the code below: func1 <- function(x, mu){ (mu^2)*dnorm(x, mean = mu, sd = 1)*dgamma(x, shape=2)} m1star <- function(x){ integrate(func1, lower = 0, upper = Inf,x)$val} T <- function(x){ 0.3*dnorm(x)/(0.3*dnorm(x)+0.7*m1star(x))} func2 <-

[LLVMdev] Integer ID for LLVM::Instruction*?
Hi, I wonder whether we can easily retrieve an LLVM instruction ID that uniquely identifies the instruction. In my case, I need to avoid using llvm::Instruction* directly. Given an 'inst' of type llvm::instruction*, is there some readily usable method as simple as "int id = inst->id( )"? Thanks. Zhoulai -------------- next part -------------- An HTML attachment was

Getting names of objects passed with "..."
Is there a tidy way to get the names of objects passed to a function via the "..." argument? rbind/cbind does what I want: test.func1 <- function(...) { nms <- rownames(rbind(..., deparse.level=1)) print(nms) } x <- "some stuff" second <- "more stuff" test.func1(first=x, second) [1] "first" "second" The usual

A "hello world" coverage sanitizer
Thank you, kcc. I am unsure if I misunderstand your reply. It seems that trace-bb, rather than trace-pc, fits better for my problem, given that my instrumentation is to put before each conditional statement. Do I misunderstand something here?

[LLVMdev] Strange pointer aliasing behaviour
I'm hitting a strange pointer aliasing "bug".

[LLVMdev] Determining the base offset of the stack for a function.
I am running into an issue where if I have multiple functions compiled in the same compilation unit the stack offset is not starting at zero. For example: func1(...) { ... } func2(...) { ... } Say the first function uses 64 bytes of the stack and an assumed offset of 0 and the second function uses 32 bytes of the stack but an assumed offset of 64. I've found out how to get the

Is there a way to source from a specific Git repository without hardcoding the location everywhere?
Folks, A small group of us are working together to develop a set of R functions to support data management and analysis using Eclipse/StatET in a Windows environment. We are using Git/EGit for version control. We work within our own repository and occasionally push to a common remote location. I'd like to have the code source files from the 'local' git repository without

[LLVMdev] Transforming SwitchInst to BranchInst
Hi, Are there some built-in LLVM transformation pass, or written library code that transforms LLVM::SwitchInst into if-condition statements (LLVM:: BranchInst)? The purpose of the transformation is that we have a legacy program analyzer that includes an LLVM pass manipulating if-condition statements. Statements of LLVM::SwithchInst should have been handled in the same manner but was not done.

[LLVMdev] Loop Unfolding in LLVM
Hello, I am looking for a loop unfolding procedure implemented in LLVM that helps to transform a while-loop to n-layer If-statements. The transformation should be on IR, although the example below is illustrated on the source level. original loop: * WHILE (condition) DO action ENDWHILE* Expected unfolded loop (2-layer): * IF (condition) THEN* * action* * IF

Communicating from one function to another
My question is a seemingly simple one. I have a bunch of user-defined functions which compute such-and-such objects. I want to be able to define a variable in a particular function, then make use of it later, perhaps in a different function, without necessarily having to move it around in argument lists. In the C community, it would be called a "global" variable. Question 1: Is this

Finding scratch register after function call
Thanks Bruce, and elaborately as ever. Again, I'm surprised about your very thorough Z80 knowledge when you said you only did little on the ZX81 in the eighties :D OK, understood. I was first thinking about doing something like this for small frames: 1. push bc # 1 byte; 11 cycles - part of call frame-cleanup: save scratch register +-----begin call-related 2. ld
