Hi all, in this case: ... int* p = ... int* q = p; ... How can I know that data-flow from p to q, i.e., which LLVM pass of header files could I use? Thank you all. -- Best regards, Wen-Han -------------- next part -------------- An HTML attachment was scrubbed...

Thanks very much for all of your answer. I was confused by definition of 'portable' by my own thinking. Now I Correct that. (ILP32 is in another project, It's my typo. Thanks) So let me make a conclusion about this. LLVM IR can be a portable language, just depending on our front-end configuration or origin language limits. Did I mistake that? Thank a lot all of you. 2010/12/22

Hi all, I know __builtin_va_list is target-specific, and ARM has typedef void* __builtin_va_list; X86 has typedef char* __builtin_va_list; It seems they can be treated as the same prototype,i.e.. void*, at the header level. What I want to ask is: If I write a program use "typedef *void** __builtin_va_list" on X86, and run it. Would I face any problem on run-time? I think it won't

Dear all, AFAIK, ARM EHABI is not ready for both asm and obj emitter. Some people including me what to implement them. My question is, to avoid duplicate effort, does someone take charge of this part? or does anyone is already implementing this currently? BTW, any suggestion on this effort? I'm very appreciated! Thanks in advance! -- Best regards, Wen-Han Gu (Nowar) -------------- next

Dear all, I'm a beginner in LLVM field. If any rudeness, I feel sorry to that. I have checked-out the source and built successfully. Now I want to use it, so I write a simple code. // context.cpp #include "llvm/LLVMContext.h" int main() { llvm::LLVMContext& context = llvm::getGlobalContext(); return 0; } $ clang++ `llvm-config --cxxflags --ldflags --libs` context.cpp But

Thanks for your answer very much. I wonder for what reason does ARM use *void ** but X86 use *char ** ? Seems ARM uses void * since its spec said that. But X86? I cannot find any reason or spec to specify why X86 uses char *, not void * directly? Could anyone give me some hints? Thanks a lot. 2011/5/23 John McCall <rjmccall at apple.com> > On May 22, 2011, at 8:49 PM, Wenhan Gu wrote:

Hi all, I have a source code: int* p = malloc(...); After translating to llvm::Module, We can know the source code did not call free. I know we can hack this into Module. But my question is, could we hack it back to source code? After fixing, the source will become: int *p = malloc(...); free(p); Is this feasible? Thanks all very much. -- Best regards, Wen-Han -------------- next part

Hi, I'm running dovecot on a small server. I put all my mail from the last 10 years on it (approx. 160 mb). I'm seeing terrible performance. Sometimes, my client needs several minutes to display a message. This is with mutt, thunderbird and evolution. Copying an outbound message to the Sent IMAP folder (15k messages) typically takes a few minutes, but can be quite fast on occasion

Dear all, I cannot find the answer of this question. We all know LLVM IR is portable, but it uses ILP32 and record the target layout within the IR. target datalayout = "e-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64 :64:64-f32:32:32-f64:64:64-v64:64:64-v128:128:128-a0:0:64-s0:64:64-f80:128:128-n8:16:32:64" target triple = "x86_64-linux-gnu" It seems it already assigned

What's the best approach to running latent class analysis with R? I've downloaded both randomLCA and poLCA packages, but I am interesting in running a standard LCA with individual records (not frequency table) as input data.

Folks, I am linking from page A to page B, and back again. When I go from A -> B, the B_controller.rb runs fine, and the page renders properly. But, when I go from B -> A, the A_controller.rb doesn''t run again, so the array (@A) is nil (which causes a problem). Should the controller run each time the page is accessed? Any ideas?

Hi I tried to install the * in my Radhat 7.3 machine. The "gmake" and "gmake install" went fine, but "gmake sample" gave me errors of "configs/*.adsi", "sounds/demo-*" and "sounds/*.mp3" errors. I created a dummy.adsi in the configs folder and commented out the "sounds/demo-*" and "sounds/*.mp3" in the Makefile to

Hi, I wonder if anyone knows how to control color and darkness of the background grid generated by ' type = c("g", "p") ' in a lattice plot (e.g., in xyplot). The documentation does not seem to offer a way to change them. Thanks a lot! Wen

I'm wondering what's the best way to shift a huge matrix left or right. My current implementation is the following: shiftMatrixL <- function(X, shift, padding=0) { cbind(X[, -1:-shift], matrix(padding, dim(X)[1], shift)) } X <- shiftMatrixL(X, 1)*3 + shiftMatrixL(X,2)*5... However, it's still slow due to heavy use of this function. The resulting matrix will only be read once

Hi, Sorry if this is a repost. I searched but found no results. I am wondering if it is an easy way to construct the following matrix: r 1 0 0 0 r^2 r 1 0 0 r^3 r^2 r 1 0 r^4 r^3 r^2 r 1 where r could be any number. Thanks. Wen [[alternative HTML version deleted]]
