...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 simple pass to test it. The content of Makefile is LEVEL = /opt/llvm LIBRARYNAME = StatBB SHARED_LIBRARY = 1 include $(LEVEL)/Makefile.common Once I do make, I got a error like " /bin/sh: line 1: cd: /ho...

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://ww...

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.

...test.c -o test, bytecode file test.bc is optimized ( llvm-dis< test.bc). Does it mean there is default optimaztion option when running llvmgcc and can I disable the option for optimiztion? By the way, I can get the almost exactly matched assemble code by using original gcc -c test.c. Thanks, Qiuyu -------------- next part -------------- An HTML attachment was scrubbed...

...Instuction pointer) and push_back to instList. But I failed to do it. Instruction *NewInst = ; NewBB->getInstList().push_back(NewInst); So I was wondering if it is allowed in LLVM or not, if so, how to do that? Let me know if my question is not clear.

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], %ESI mov %EAX, DWORD PTR [%ESP + 120] mov %ECX, DWORD PTR [%ESP + 124] mov %EDX, DWORD PTR [%ESP + 128] mov %ESI, DWORD PTR [%ESP +...

...oint type operand by this way, right? If so, is there any way I can insert IR code whose operand are float point. I am trying to find some else class (not binaryOperator) to solve this problem, but I didn't make it. Thanks. BTW, allocaInst/storeInst/loadInst those works well for float point.

...e limitation is that for some case, for example, the instruction look like call %eax jmp %eax I cannot grab the entry address of BB :(. When I use llvm, llvm can get the entry for this case, how could llvm get. I haven't read the code. Any opinion is welcome. Hope it useful. Qiuyu > This can be done with a quick hack.

...de function to recover original bytecode m.bc. Actually, I would to compile m1.bc and decode library to executed file, and once I run m1, at first the decode function at entry of main should be run before any code running. So now the decode part is llvm pass, could I do it like what I want? Thanks Qiuyu decode pass: using namespace llvm; #define endl "\n" namespace { struct DecodeStr : public FunctionPass{ virtual bool runOnFunction(Function &F); private: void DecodeString(Module *M); void get_randKey(Module *M); Constant *randKey; }; RegisterOpt<DecodeSt...

...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 block, I don't know how to do it. Thanks for any response. Qiuyu -------------- next part -------------- An HTML attachment was scrubbed...

...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 -------------- next part -------------- An HTML attachment was scrubbed...

...is that I don't know how complex process ptrace did. So I really want to write some assemble code or C to do it if I can. If I can finish the first step, I will find some optimization method based on BB to improve the performance. And then .... Is it clear for my project? :-) Thanks again.
