Nope, there currently isn't a uniform interface for doing so, at least not at the LLVM level. As you said,

Because there is already a built-in support for graphs, I hoped there is also built-in support for data dependence graphs. That would allow, for example, to display them naturally with dot utility.

I tried CC=gcc44 CXX=g++44 ../llvm/configure and got CC=gcc44: Command not found So the syntax is indeed as wriiten in the help.

Isn't it? while you might think so, try it the other way round. Also, by doing make VERBOSE=1 you can see which compiler is really being used. Ciao, Duncan. > >

What is the best level to use for backend development? We do not need to generate machine code, but rather an intermediate representation that will give us the control flow graph. Is this the llvm IR? If so, how do I read into memory a file that was generated by clang++ -emit-llvm <source file>.

Hi, I am new to LLVM, so I am sorry if the question I am going to ask has already been raised before. I will be thankful if anyone can describe me a quick way to search relevant topics within the list archive, When I am trying to compile a simple code, containing access to std::string, with clang: #include <string> int main() { std::string s; return

Hello, We have installed RHEL 5.2 Server ( i386 image ) on a machine with 64GB of RAM. When booting the default PAE kernel ( 2.6.18-92.el5PAE ) that is shipped with RHEL 5.2 installation the OS detects 64GB of RAM. But when booting the Xen kernel ( 2.6.18-92.el5xen ) the OS detects only 14GB of the total amount of available RAM. Did anyone encounter this problem before ? Is it a normal

Hi Martin Here is some more info in the libvirt/qemu/instance...log file . Does it help in resolving the issue of : error : qemuMonitorIO:614 : internal>error End of file from monitor In the libvirtd.log file I sent you could see clearly that the debug option is active and this is the most detailed info available (or some better option than log_leve=1 exists ?) Thx Zvi Dubitzky

Hello Lang, Thanks for your answer. I am now looking for an example of the usage of CompileOnDemandLayer. Is there an example available for that (could not find one in llvm/examples)?

Ok, I got. You should install libstdc++44-devel, too. Please try to install gcc44-c++ and libstdc++44-devel. Note: gcc44-c++ depends on gcc44, but gcc44-c++ and libstdc++44-devel are independent each other, at least on my host, CentOS5. ...Takumi 2012/7/15 Sitvanit Ruah <RUAH at il.ibm.com>: > In order to isolate the problem I am now running on a machine whose only > installation

Hi Again, I'm a little confused regarding what is the exact Orc's functions I should use in order to save the functions code in a code cache so it could be later replaced with different versions of it and I appreciate your help. Just a reminder I want to dynamically recompile the program based on profile collected at the run-time. I would like to start executing the program from the

In order to isolate the problem I am now running on a machine whose only installation of gcc/g++ is gcc44, g++44 For this installation I am getting the following error: COMPILE: clang_linux/asan-i386/i386: /gpfs/haifa-p4/00/pincette/sitvanit/LLVM/llvm/projects/compiler-rt/lib/asan/asan_new_delete.cc /.../sitvanit/LLVM/llvm/projects/compiler-rt/lib/asan/asan_new_delete.cc:19:10: fatal error:

Hi Revital, The CompileOnDemand layer is used by the lazy bitcode JIT in the lli tool. You can find the code in llvm/tools/lli/OrcLazyJIT.* . Cheers, Lang.
