Hi, I am trying to use the CloneFunction from llvm/Transforms/Utils/Cloning.h and I don't understand how the ValueToValueMapTy argument should be initialized. For instance, let say I want to clone this function (to add an argument): define void @function(i32 %i) #0 { entry: %i.addr = alloca i32, align 4 store i32 %i, i32* %i.addr, align 4 ret void } to another function which should,

For testing purposes, on a small set of users, we've run the courier-dovecot-migrate.pl script. We are converting from Courier 0.43 to Dovecot 1.2.9. For the most part, things seem to be ok. However, an iPhone IMAP client user is reporting a problem where some of her messages don't show up. Even stranger is the fact that these same messages do appear when using Outlook 2k7 for

Dear R-helpers, I am trying to generalize my function for recording measurement times from file times "mtime"--my intervals are minutes to hours over the course of several days. I want to use hours as my units, and I have had trouble dealing with time units in a general way. I have a simple solution for the dealing with regular intervals, but I have not been able to handle irregular

Hi all, I'm getting rather odd behavior from a call asm inteldialect(). TL;DR is "mov reg, $0" with a "i" constraint on $0 is behaving identical to "mov reg, dword ptr [$0]" and differently from "movl $0, reg" in AT&T syntax. I'm not sure how to get clang to emit an inteldialect, so for this example, I'm emitting llvm and then modifying

After poking at my installation of rust, I'm not entirely sure what version of LLVM it uses. Looking at the GitHub page, it looks like Rust maintains their own copy of llvm and cherry picks commits. The C example was

Peter, I am trying to get memdisk to work with grub and have run into a problem. Grub loads memdisk into the 0x9000 segment and then starts it at location 0x90200. I run into problems in the first printf statement. It turns out that printf uses a switch statement that compiles into a jump table. When I reach this jump table, I believe the code is jumping into hyperspace due to the jump table

I'm doing the delay slot optimization for MIPS and I've noticed that two other ports that are doing this have to work around a problem in the instruction abstraction. Would be nice to fix this and not propagate the hack. The basic problem is that on a call, you want to get the set of explicit and implicit operands but NOT the variable operands. There is no way do this without

Hi all, I'm working for translating dex bytecode to LLVM IR In order to communicate with Android interpreter, The work have to add data below some instructions I want to use inline assembly to add data. Thus, I wrote a little program to find out the related LLVM IR int main() { asm(".long 0x12345678"); return 0; } and I use clang to translate it into bitcode It's the

Hi all, I'm trying to land (a rebased version of) http://llvm.org/D37461 - which should make it possible to handle x86 Intel assembly like mov eax, offset Foo::ptr + 1 (Currently, omitting the +1 works... but offset doesn't work in compound expressions.) I'm having trouble figuring out what inline assembly I can emit into the LLVM IR that will work properly. So far, the closest

That is, essentially, your task. You could compile it under callcatcher, or use some other symbol dependency

Hi all, I am currently looking for more accurate debug information. In particular I am interested into relating load and store IR instructions to the corresponding array subscript. Current debug information associate each instruction to the source code line they come from. I would like to extend this, for loads and stores only, to make metadata point to the source location where the array
