Hi, I want to annotate values in llvm, like making a flag for the operands and result of an instruction for future use. I wonder if there's any interface to do such a thing? Thanks! -- Shuhan

Hi: I want to pass some message of instructions from LLVM Internal representation to backend code. For example, I make a flag for some certain operands of certain instructions. How can it be passed to the backend instructions? Which programs I should look into? Would someone give me some idea? Thank you ! -- Shuhan

Hi: I have extended the IR for adding flag. But I just want this flag to pass through the backend machine code. I know there're several passes like register relocation, schedualing, etc. But I think I just miss the part which is used to "parser" the LLVM IR to machine code instructions. Would you give me some help? Thank you ! > On Sun, 10 Jul 2005 shding at mtu.edu wrote:

Hi, I'm changing bytecode format a little bit, i.e. for 2 operands Instructions, the original is like this: 01-00:Opcode type 07-02:Opcode 15-08: Instruction type 23-16: Operand#1 31-24: Operand#2 My change is like this: 01-00:Opcode type 07-02:Opcode 15-08: Instruction type 16: myflag1 17: myflag2 24-18: Operand#1 31-25: Operand#2 I do

Hi, I have some problems when I use this command: gcc hello.s -o hello.native(for example) to assembly the native language to a program. I always got a error message like this : "gccas: hello.s:3: parse error, unexpected $undefined. hello.s:3: while reading token: '.' " I don't know what's wrong here. By the way, when I learned llvm at the first time, I followed

Hi, In the directory of lib/CodeGen/SelectionDAG, I cann't find SelectionDAGISel.cpp. I only have DAGBuilder.cpp and SelectionDAG.cpp. I don't know why. My edtion is 1.4. Is it because of the edtion difference? Thanks! > On Mon, 11 Jul 2005 shding at mtu.edu wrote: >> I have extended the IR for adding flag. But I just want this flag to >> pass through the backend

Hi: For some reason, I changed the files /ByteCode/Writer/Writer.cpp and /ByteCode/Reader/Reader.cpp and I introduced an new version number 6. Now I replaced these two changed files with the original ones that are version 5. And I rebuild the llvm compiler. What make me mad is that the bytecode produced now is still version 6! Of course the reader cannot recognize it because the current reader

Hi: In the file of SparcV9BurgISel.cpp, you said you didn't implement the "Switch" instruction and I also can't find how the "Select" instruction is implemented. So do you do some work to handle these two kind of instructions in other parts? Where can I find it? Thank you! -- Shuhan

Thank you. I'm only consider about how the compiler comiles c program to LLVM IR. I know there should be a scanner, parser, and IR generator. But where is the main entrance and how about the flow of the process, especially about the IR generator? > shding at mtu.edu wrote: >> Hi, >> Where can I find the main function of llvm compiler in the source >> file? >>

Hello, The interface is named Annotation and it allows any Annotable object to be annotated. Note that the Value class is an Annotable. HOWEVER, if the annotation information is something that might be useful to other developers or to other analysis/transformation passes, you're strongly encouraged to create an Analysis instead. See the various analyses in include/llvm/Analysis for examples.

If you're talking about the llvm-gcc and llvm-g++ compilers (C/C++ to LLVM) then they are in the downloadable tarballs available here: http://llvm.cs.uiuc.edu/releases/. You

Hi: When I tried to use llc -march=sparcv9 to compile some llvm .bc to SparcV9, I got such error: llc: /llvm/lib/Target/SparcV9/SparcV9RegInfo.h:62: virtual void llvm::TargetRegClassInfo::markColorsUsed(unsigned int, int, int, std::vector<bool, std::allocator<bool> >&) const: Assertion `UserRegType == RegTypeWanted && "Default method is probably incorrect for

I have an element where I do a BlindDown on mouse over and a BlindUp on mouse out... The problem I am seeing is if I take my mouse off befor the first blind down is all the way down, the blind flickers and it is competing at lowering and raising the blind simultaneously. I assume (hoping) there is some way to ether : 1) Have blind up wait till blind down is finished befor going back up

Hi, when pushing libguestfs 1.27.53 (1:1.27.53-1) through my build setup befor uploading it to Debian, I noticed that "guestfs_internal_lstatlist@Base", a symbol that has been there since 1.20, is now missing. This causes dpkg-gensymbols(1) whose job it is to compare the symbols from the newly-built libraries to the known state to fail. If the guestfs_internal_* functions are not

Which bytecode files? Perhaps the ones in the runtime library? If these were built with Bytecode V6, then the reader (V5) will not read them.

I have to compute some standard errors using the delta method and so have to use the command "numericDeriv" to get the desired gradient. Befor using it on my complicated function, I've done a try with a simple exemple : x <- 1:5 numericDeriv(quote(x^2),"x") and i get : [1] 1 8 27 64 125 216 attr(,"gradient") [,1] [,2] [,3] [,4] [,5] [,6] [1,] Inf
