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, 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

Is there any way to see the called number when a call gets redirected to the 'a' extension from voicemail? Say x123 calls x456 and it rolls to voicemail. x123 hits * and gets dumped into the 'a' extension in the original context. I need some logic in 'a' to do a database lookup based on the original called number (x456). Any ideas? When I do a test, it appears

There are 4 sets of array, each have 2 dimension data:x,y. And these data comes from bkde. I tried to plot them in one figure, but details of some lines, like peak and where it locate, have diminished since one set of array have fairly high y value.And another array have lots of y value near zero, like 1e-20, 1e-10, like a long tail, while the highest y value of these arrays is 1e-4. Does R have

Hello everyone, I am having a bit of problem getting MusicOnhold to play. I am running Asterisk 1.4 with MPG123 0.59 installed. And here's what i see in the debugging window of asterisk: -- Started music on hold, class 'default', on channel 'SIP/x123-082043d0' -- Stopped music on hold on SIP/x123-082043d0 Any idea why it is not playing the file at all? thanks

Dear All, I would be grateful if you can help me. My problem is the following: I have a data set like: ID time X1 X2 1 1 x111 x211 1 2 x112 x212 2 1 x121 x221 2 2 x122 x222 2 3 x123 x223 where X1 and X2 are 2 covariates and "time" is the time of observation and ID indicates the

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, 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

The macro $src, $dest used in Instruction::AsmString must be "declared" in Instruction::OperandList, right? $$ has special meaning?

Thanks Andrew. I still do not understand your method. Would you mind telling me more? Thanks. But for hash problem, it is common problem for hash. We cannot make sure the mapping is 1 to 1. I used a way to grab the BB address, but there is some limitation. What I did is that I rewrote some part of disassemble tool. During the disassembling, I check all the conditional/unconditional

I'm using the excellent --link-dest option on rsync to do every-day full backups of a number of servers. These servers share most of the file-system content, but of course has some variations. In order to reduce the space used for each backup, I was thinking about linking all files in the backups to their hash in a separate directory, allowing only one storage of each file-value, reducing

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.
