similar to: [LLVMdev] What's the meaning of [0 x sbyte*]?

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

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.

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

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

Xia, LLVM doesn't really use type qualifiers the way you're thinking about it. In LLVM parlance, types are neither const nor non-const, they just define the fundamental nature of a value. However, LLVM fully supports Constant Values (see include/llvm/Constant.h) and constant global variables (see include/llvm/GlobalVariable.h). You might want to read up on the LLVM IR a bit here:

Hi, Chris I get a new PostDominanceFrontier class by combinating the code of 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.

lizhuo,您好！ 不是很明白你的意思，好像你想从一个ConstantExpr::getPtrPtrFromArrayPtr 指针得到这个ConstantExpr 的内容， 但你的困难在哪里？ ======= 2006-03-25 22:04:14 您在来信中写道：======= >hi >I have one llvm program like this : >.. >; define ConstantArray >"E1$str" = internal constant [3 x sbyte] c"E1\00" > >; use getPtrPtrFromArrayPtr to define SByte* from ConstantArray

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 ��

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 Chris, I took a haste look at the "Points-to Analysis in Almost Linear Time" by Steens , your PHD thesis and SteensGaard.cpp in LLVM this afternoon. So I think: 1. Actually the basic algorithm described originally by SteensGaard does not provide MOD/REF information for functions. 2. The context insensitive part of Data Structure Analysis (LocalAnalysis) can be deemed as an
