Hi, I have couple of questions that those who design unconventional passes would be interested in. 1. How to move a virtual register data to another new virtual register? It seems like that there is no LLVM instruction similar to mov machine instruction. Arithmetic or logical operators could be used for integer variables but what about pointer variables? 2. What is

Thank your for reply. The reason why these information are needed is that I am trying to extract the program signature (e.g., control flow) out side of the binary. Conventional compiler technique adds extra checking code into the target source or target IR in an invasive manner. Since code generator combines the added code with the original one, they don't need to correlate these two

Can you tell us what goal you are trying to accomplish that requires you to do this? There might be better ways of doing what you want. The answer to your question probably depends on whether you're trying to write a

Does anyone succeed at compiling Linux kernel for Sparc v8 architecture? I am currently trying to expand the regime of LLVM to Sparc kernel codes. The following is the initial error messages. Any comment is welcomed. #1. Inline Assembly Code: register struct thread_info *current_thread_info_reg asm("g6"); Error Message: include/asm/thread_info.h:77: error:

Hi, How to correlate the LLVM IR-leve instructions and memory values with the machine instructions and memory locations? For example, if CMP instruction in machine ISA is selected for the ICMP instruction in LLVA, with the Instruction datastructure for ICMP, is it possible to get the memory address of CMP instruction? Assume that the code segment base address is given. Similarly, by

Hi, This is a simple question about building ARM cross-compiler. What is the building procedure using LLVM 2.4 and GCC front-end 4.2? I used these commands for LLVM, and it is okay. $ ../configure --prefix=/usr/local -target=arm $ make ENABLE_OPTIMIZED=0 $ make ENABLE_OPTIMIZED=0 install Then these commands were used for GCC front-end but this got couple of errors. $ ../configure

Please run. $ llvm-gcc -O3 -emit-llvm hello.c -c -o hello.bc $ llvm-dis < hello.bc > hello.ll The first command is to generate a byte code and second is to translate the bytecode to a readable form.

hello ( and sorry for my poor english ... ) I'm a newbie on R software and I need to obtain this kind of system : a structure, like a liste : my_struct <- list() my_struct$a <- a_value my_struct$b <- another_value my_struct$c <- one_more_value and a function with two args : the first is a instance of the structure, and the second is any component of the structure (here $a, $b

Hi everyone. I want to get the llvm IR from the C source code by LLVM-GCC. But I am not familiar with those command line arguments. Can anyone give me a guidance? Thank you very much for any help. Good luck. -- Best regards. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Currently I have a trick to extract the correlation information of LLVA and ISA. By adding an intrinsic instruction and comparing the emitted binary with the original one. The location of machine instruction that I am interested in is calculated relative to the intrinsic instruction. Unless I change the original instruction with the intrinsic having a same size, this needs many iterations as much

Dear helpers, I'm using R version 2.8.0. Suppose that I have a small data set like below.

Dear all, I'm using R2.8 version, and am trying to do NMDS and calculate other diversity indices in vegan package. The problem is that it works with a small set of data (43 X 23; row by column), but the following error message comes up with a larger data set (43 X 104) (it seems not large to me at all). I made it sure that all data are of numeric type as required. >gh1.H=diversity(gh1)

Dear R-list Suppose I have a data set stored in hmet, for which I did get confidence limit on a linear regression as shown below.

Thanks Jim for pointing out how to properly ask. Here is is my question and a small subset of the data and output. I have a data set with many blanks. The blanks should be replaced with zero once imported. I tried read.table, read.csv (R 2.8 version),or scan, but none was successful. Any suggestion, please.. thanks.
