Thanks Edwin. I found DebugInfo.cpp may be useful. Could you tell me which function I should call inorder to know the source file name and the line number for a particular instruction?

Hi, I had cloned zorg from https://llvm.org/svn/llvm-project/zorg/trunk, then I try to start the buildbot master located in buildbot/osuosl/master (the absolute path is /nfs/home/hongbin.zheng/buildbot/zorg/buildbot/osuosl/master) by simply typing "buildbot start" And I get something like this from my twistd.log: --- <exception caught here> --- File "/usr/lib/python2.7/dist-packages/twisted/internet/defer.py", line 545, in _runCallbacks curre...

...abs and there is no select, %res = OP i32 %b, %a %sub = sub i32 0, %b %res2 = OP i32 %sub, %a theoretically, we can still do the following transform for the above pattern: %res2 = OP i32 %sub, %a ==> %res2 = sub i32 0, %res Not sure whether we can do it in instCombine.

...(a,b,c); i++) then I should rewrite it as: tmp_var = foo(a,b,c); dumpInfo(...) for (int i=0; i<tmp_var; i++) { ... tmp_var=foo(a,b,c); } This looks quite complicated! Does anyone has any ideal about how easy to insert some basic blocks and to rewrite the loop header in LLVM?

We found several issues in ChangeSet 10319. ChangeSet 10314 should work according to our test log. 1, xen0 can not be compiled for IA-32/IA-32pae host since ChangeSet 10318. We tried gcc 3.4.2 and 4.1.0 but both failed. 2. On IA32e host, VMX can not be created. "xm cr" complains: Error: Not an HVM capable platform, we stop creating. 3, On IA32e host, "reboot" can not

...at the byte code level? I am writing a passer and if will be nice if I can know which line in the source an instruction (or value) corresponds to. I found a document online: http://llvm.org/docs/SourceLevelDebugging.html, but I can't find an example of doing it at the byte code level. Cheers, Zheng

...to use 'as' to compile the assembly code to an object file, and finally I can use gcc to generate an executable program. *****My question is*****, is there any way to automatically evoke the pass manager, such as: llvm-gcc -c test.c and in such a way my own pass will be evoked? Cheers, Zheng

...ive source order. In unswitch2() they have been permuted, and the algorithm cannot deal with this. This requires some kind of value numbering to do efficiently. The GVNSink pass that I really should get around to updating should solve this, eventually!

Hi Eli, Could you tell me how to extract the variable name? The reason I want to do it at the IR level is because I have more information at this stage, such as, constant propagation and back edges.
