Hi: I have just started to use llvm and confronted with a problem: when I want to transform something very simple for name.ll to name.bc with llvm-as name.ll, some errors occured: error: parse error, expecting `GLOBAL' or `CONSTANT' while reading token: 'target' btw, the name.ll file is as follows: ; ModuleID = 'tst.bc' target datalayout =

This is not llvm-gcc specific; it happens for regular gcc too. It's needed to support overloading multiple functions called 'bar' with different parameters, (which C++

Hello all, I'm getting started on a project using LLVM's opt tool to do static analysis, printing call graphs and such. When compiling C programs to IR (and eventually to call graphs), function names remain the same (main, function1, function2 etc.), but when compiling the same program as C++, the function names often have cruft added to them (_Z9function1v, _Z9function2v etc.) which

Got it, thanks. But in my pass, I use function name to locate. Can I disable mangling in clang?

Hi all, I'm pretty new to LLVM and am slowly learning the code-base and architecture, mostly as a result of my efforts to implement a target backend. There are a number of resources (read: documents) available which deal with some parts of backend development (and LLVM development in general), but sadly they are not at all comprehensive. I'd like to propose that a wiki be made available

Hi, I compile a .cpp with cmd: clang++ -emit-llvm -c -g -O0 -w pbzip2.cpp -o pbzip2.bc -lbz2 llvm-dis pbzip2.bc One function in .cpp is consumer_decompress. However, I look inside pbzip2.ll. The function name is changed to "define i8* @_Z19consumer_decompressPv(i8* %q) #0 {" Why clang adds a "_Z19" prefix and "Pv" suffix? Thanks,

Hi LLVM-Folks, as mentioned in an earlier post (http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-July/051677.html) I am currently working on a Back-End for the TriCore processor. Currently, I am struggling as LLVM could not select zext and load, for instance, so some of the testcases in test/CodeGen/Generic are not successfully compiled by my back-end. Furthermore, I am completely puzzled by the

I tried, but seemed not to work. For example, when I run a command as below: c++filt _ZNSt4listIiSaIiEEaSERKS1_ The output remains the same as the input symbol. By the way,

Hello everybody, I'm curious whether there have been any attempts to perform performance analysis on the LLVA level. I am interested in the derivation of flow-facts (loop bounds etc. - what about the value-range-propagation pass I read about on this list some time ago) but even more I am interested in exec-time modeling (how long does it take to execute a bunch of LLVA instructions on

We are using now dovecot 2.0.21 with open-ldap, but this situations has already taken a quite long time. When user changes the password, we have to reload dovecot every time, otherwise the change is ignored and dovecot sees only the old password. Any ideas where the problem might exist?

Hello John, Thank you very much for your fast response and the patch. Is it possible to add Fabian Scheler and Florian Franzmann to the people section as proposed in the attached patch? I hope to manage to write a description for the 'ProjectsWithLLVM' page this week and send it to the list. Thanks again, Tobias Am 26.09.2013 21:26, schrieb John Criswell: > Dear Tobias, > >

Hey all, Just wondering if LLVM has any command options or tool to allow for demangling C++ names from the LLVM bitcode? Thanks! Best, Xiaolong
