similar to: [LLVMdev] Is there any way to modify basic block like adding junk code or ...

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 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

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, when I run opt -globaldce -deadargelim on a module, deadargelim removes less arguments than when I run opt separately for the two passes. The module has dead functions that hold references to other functions, which makes the latter intrinsically live for deadargelim. -debug-pass=Executions shows no other passes being run before deadargelim. Why is that so? Thanks, Torvald

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

Hi, Under directory, /llvm/test/programs/external/spec, It seems there are several makefiles for SPEC. I am just wondering could I get the SPEC code or bytecode. Thanks in advance.

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

Hi, I'm somehow a newby with llvm, I've been working with it for 4 months. I'm trying to convert a function to 'main' in order to execute this concrete function only when the program is run. To do so, I've been able to remove all other functions from the module, and change the function name to "main". I've then allocated new registers for all the formal

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

I expect UCLA would have a site-wide license so

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

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 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, 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, Let's see an example (from Alexandre Isoard) first: **************************************************************************************** ; RUN: opt -ipsccp -deadargelim -licm -O2 -S < %s @g = internal global i32 0 ; Function Attrs: argmemonly define internal void @foo(i32* nonnull dereferenceable(4) %arg, i32 %val) #0 { entry: store i32 %val, i32* %arg ret void } define

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

Hi everybody, I have a rails application and a report designed by iReport. I want to combine rails and jasper to obtain a pdf document.. Sincerly, i followed the tutorial in http://wiki.rubyonrails.org/rails/pages/HowtoIntegrateJasperReports and i haven''t obtain a result because i coud''nt understand where i put these codes.. I knocked in this door and i hope to obtain your

Hello; Please coud you advise me of a simple way to select points (x,y coordinates) that fall within a polygon. I've got a set of polygons, each one defined by an arbitrary number of points, and several points inside each polygon. I know this is simple with a GIS, but I'd rather do it inside R. Thanks and best regards, Javier -----

Thank you Hal and Stefan! Bug report is filed: https://bugs.llvm.org/show_bug.cgi?id=46717 And Stefan, I think 'attributor' is a really nice pass, and can infer more precise and useful attributes, which may give more opportunities for optimization. But we shouldn't depend on 'attributor' to correct wrong function attributes, because we cannot run 'attributor' after
