Hi, When I compile httpd-2.0, llvmgcc reports many struct types and macros undeclared, but gnu-gcc can compile httpd-2.0 completely.

...f PostDominanceSet/PostDominanceTree/PostDominanceFrontier FunctionPasses. It works very well. BTW: Why the PostDominanceFrontier FunctionPasses does not use the formal argument in runOnFunction(Function &)? Does it gets the Function from PassManager? Thank you.

Hi, I got lots of "undefined reference" when building vmkit. Anyone can help to give a solution? I download vmkit with "svn co http://llvm.org/svn/llvm-project/vmkit/trunk/", followed the instructions of "http://llvm.org/svn/llvm-project/vmkit/trunk/README.TXT", and built vmkit on ubuntu 13.10 x64 with sunjava 1.6.0_45 + llvm 3.3 + classpath 0.99 + gcc 4.8.1.

Hi Has anybody tell me how to create some new type qualifies in LVM? A type qualify, like "const" in C, is useful for program analysis. I hope that I can set/get the type qualify of any value in a program analysed. Or, if I could add a property to the value class and set/get the property, it is same to add some new type qualifies. So, I simply insert a "int" private

Why some library functions (such as strcpy,strncpy,etc.) are extended in .bc file? How to keep the originally forms of these library functions in .bc file?

These come from the library: llvm/runtime/GCCLibraries/libc/ If you don't want them, just go into that directory, delet...

I want to find buffer overflows from general C programs, a bit like SAFECode :). To quicken the dataflow analysis, I wished to slice operands of character strings from C program using pgmdepgraph, but now, I thought I have to use def-use and use-def chain. Do you think it has any sense? Xia ______________________________________ ע������30��������䣨 http://mail.sina.com.cn/chooseMode.html ��

Hi I hope to use the getAliasSetForPointer(Value *p, unsigned size), the method of AliasSetTracker class, but I donot known what meaning is the argument "size". May somebody tell me? Thanks.

I can use the interfaces of AliasAnalysis in my pass, but how to specify the underlaying pass of AliasAnalysis is DSAA? Thanks.

When analysing a function "fn", my FunctionPass needs some PostDominanceFrontier information of functions which are called by function "fn". getAnalysis<PostDominanceFrontier>() cannot give the information, because it only gives the PostDominanceFrontier information of "fn", not the PostDominanceFrontier information of functions called by "fn".

The llvm I using is llvm-1.2, its cfrontend should be based on gcc-3.4, the system I using is RedHat Linux 9.0, I desire to compile httpd-2.0.51.

I want to use PgmDependenceGraph pass , but my pass cannot work with PgmDependenceGraph. I tried again in Hello2 pass, and it could not work also. The following is I did with llvm/lib/Transforms/Hello.cpp: 1.insert #include "llvm/Analysis/PgmDependenceGraph.h" in Hello.cpp. 2.insert AU.addRequired<PgmDependenceGraph>() in the getAnalysisUsage(AnalysisUsage &AU) of Hello2.

Hi When I compiled sendmail v8.11.6 with LLVM 1.2, I found some variables with strange type, such as: %sys_errlist = external constant [0 x sbyte*] ; <[0 x sbyte*]*> [#uses=3] %tmp.24 = getelementptr [0 x sbyte*]* %sys_errlist, long 0, long %tmp.23 ; <sbyte**> [#uses=1] The process of getting these is: 1. entry sendmail-8.11.6 directory 2. make

Yes! I should have looked this some days before, but I forgot it just now :). thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20040817/95dd9fff/attachment.html>

My pass has to call one function of a binary library. But when opt loads my pass, it tells me that the function is "undefined symbol". I copy the library to /usr/lib, and run ldconfig, but this is unuseful. Should I modify the Makefile? :( Thanks.

I modify the Makefile, and it is not a problem. :) > My pass has to call one function of a binary library.
