similar to: [LLVMdev] Could insert a label into basic block?

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

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

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

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.

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 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 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

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

I really appreciated for you guys' help and thanks all you guys, Misha Brukman, Vikram S. Adve, Michael McCracken, Chris Lattner and Brian R. Gaeke . I hope I can make it clear :-). I am trying ... There is application i.e decoder.c . I compile it using llvm and get excutable file/object file ( named decoder.out/decoder.o ) and decoder.s. And I wrote another code loader.c which is trying to

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

Actually, Misha, that won't work. The -C option is used directly in docs/Makefile. So the change will have to go into docs/Makefile. Either that or upgrade install to version 5. Reid.

Hi, everyone. I' have three set of registers - read-only regs, general purpose regs (read and write), and write-only regs. How should I partition them into different RegisterClasses so that I can easy define the instruction? All RegisterClasses must be mutally exclusive. That is, a register can only be in a RegisterClass. Otherwise TableGen will raise an error message. def

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 Misha. I tried the "gcc -dM -E /tmp/file.c | grep __sparcv9" but there was no output. Maybe this is the probelm, I do have CXX = g++ -mcpu=v9 CC := gcc -mcpu=v9 in the Makefile.config. Do I need to add -m64 as well? Thanks. Shukang On Thu, 7 Oct 2004, Misha Brukman wrote: > Is your compiler configured to define __sparcv9 when it compiles? > The following should tell
