I expect UCLA would have a site-wide license so

Qiuyu, The dynamic optimization project (an internal research project in our group) uses some way to map LLVM basic blocks to native code addresses. If this is what you want, perhaps you can ask Brian Gaeke (gaeke at uiuc.edu) to give you some information about how that is done. --Vikram http://www.cs.uiuc.edu/~vadve http://llvm.cs.uiuc.edu/ On Aug 19, 2004, at 5:11 PM, Misha Brukman

I'd be interested to hear how that's being done - if Brian would reply to the list about it, I'd appreciate it. -mike On Aug 19, 2004, at 3:39 PM, Vikram S.

On the pervious mail, I am trying to add label for each basic basic because I think I could get address by using nm if nm can show the address of each label, but it seems not . so do you guys have some idea how to get address for each basic block? Thanks. >I am trying to get the memory address of each basic block. So far I am trying to add the label >into each basic block, actually I need

Thanks. LLVM does not have a notion of C-style 'labels' that

Hi, I have a question about install path. Some one installs llvm1.4 under /opt/llvm as root. However, when I create a project under my home directory, I cannot do Make correctly. It should be enviroment issue, but I cannot fix it. The environment is as the following, /opt/llvm : // llvm 1. 4 /home/qiuyu/ ://my home directory /home/qiuyu/project/statBB ://my project directory I create a

Hi all, I am trying to disassemble *.bc to assemble code by using llvm-dis command, but what I got is like the following. So how could I get the assemble code like objdump? I mean the memory address for each instruction. Thanks Qiuyu llvm-dis: .text .align 16 .globl adpcm_coder .type adpcm_coder, @function adpcm_coder: .LBBadpcm_coder_0: # entry sub %ESP, 116 mov DWORD PTR [%ESP + 12],

Hi all LLVMor, I just tried to compile a simple code and analyze the number of the basic blocks. But after compile, what I got, the bytecode is seems to be optimized bytecode. So the information of basic blocks is not what I expected. I want ot use the code as example to see how some of code optimization methods work. However, after compiling file using llvm test.c -o test, bytecode file

Thanks Chris, but the method you mentioned is not what I want. Maybe I didn't make it clear. As you said, /runtime/libprofile is runtime library for the following function. llvm_start_func_profiling llvm_start_block_profiling llvm_start_basic_block_tracing llvm_trace_basic_block And those above functions can be inserted into basic block etc for getting profile. However, those

Thanks John and Chris. I could get the address information by the way you guys mentioned. But it is not what I want, because it will lose information about the entry of basic block. Actually what I want to get is the address of each entry of basic block. Now I am trying to declare the label of basic block as global type, hopefully I can get it from symbol table. Can I get it by this way? Thanks

Hi, Thanks Chris. Following your suggestion, I wrote the code to hide the visible string. Thanks again. Finially, I just realized my LLVM still is 1.2, not 1.3. Now I update it to 1.3. > > > 5.

Thanks Chris. I did inserting function into code before using the way you mentioned, such as call a external function. But coud I insert some assemble instructions into *.bc ? what I want to do is to implement polymorphic engine like ADM. It can change the binary code which looks like different but the functionality is exactly same. The simple way to do it is to add some junk code like NOP(

Hi, I am trying to get the memory address of each basic block. So far I am trying to add the label into each basic block, actually I need add the label at front of each basic block and then I can use command 'nm' to find the memory address for each basic block. That's the way I got. I don't know if there is another way to do it. Thanks. So now I need add label to each basic

Hi, I am working on a project with LLVM. What I need to do is to generate/insert some dummy/dead basic blocls which never have chance to be executed and put some instructions in those dummy/dead basic blocks. So far, the dummy/dead BB insertion is done. I am trying insert instructions in those dummy/dead BB. Actually, I can insert the legal instructions to dummy/dead BB, however, I really want

Hi, From the file HowToUseJIT.cpp, I learned how to insert some calcuation IR code like Add/Sub/Mul etc by using Instruction *Add = BinaryOperator::createAdd(One, ArgX, "addresult", BB); By following this way, it works well when I insert some IR code whose operand is integer type like IntTy, however, when I tried to insert similar thing whose operands are float point, I got the

The easiest way to do this is to copy one of the samples in llvm/projects (such as

Hi, Is there a way to modify the string such as char a or char b? Could I use the way like "Replace an instruction with another Value" in Programm Manual? In fact, what I am interested in is string with visible expression, not all string, and I am trying to hide the orignal string by using simple way like XOR.. Is there a way to reorder the basic blocks? Thanks. Qiuyu C Source

Hi, I am trying to insert a Loop IR into the existed bytecode file. insertion part by C code, char *p[n]; // pointer array for storing the address of strings int i; for(i=0;i<n;i++){ (p[i])[2] = (p[i])[2] ^ 0x27; } My questions are 1. for local variable 'char *p[n]' , it is represented by IR as alloca ...., so could I insert local variable (pointer array) directly as same way

Hi , Is there any way to modify code like adding junk code or mess up the order of a bunch of codes(in same basic block) which is no dependency? I saw some options like -dce -deadargelim for 'opt' , but what I want is to reverse to do it. I mean adding some dead code or junk code. Actually what I want is to implement a ploymorphic engine. Coud I do those by using llvm? Thanks. Qiuyu

Thanks for your reply. After I change Cstr to gI, it compiled successfully. Thanks again. Another question is for constructing getelementpt. // C code char gStrA[10] = "test str"; // here is Global variable,gStrA and initializer "test str" char gStrB[10]= "test str2"; main(){ int = i; char *pGVars[20]; // here, the pGVar is for storing the address of each
