Hello Villmow, Is it your backend EFI Byte Code Virtual Machine?? Would you mind to give me an example about what pseudo instruction you add?? thanks a lot yi-hong 2011/1/19 Villmow, Micah <Micah.Villmow at amd.com> > I have this same problem in our backend.

Hello all, I am adding a new target into LLVM. However there is a assembler for that target and I just want LLVM to generate assembly. I read the document "Writing an LLVM Backend". I am wondering to know whether I can ignore the Inst field in the following example: class InstSP<dag outs, dag ins, string asmstr, list<dag> pattern> : Instruction { field bits<32>

Hello David, Thanks for your example. Is that means that DAG pattern is consist of LLVM IR instruction?? I met an example [(set CPURegs:$dst, (OpNode CPURegs:$b, CPURegs:$c))] of MipsInstrInfo.td, but I can't find correspond LLVM IR instruction of "set" in "LLVM Language Reference Manual". Is that correspond to $dst = op $b, $c?? Would you mind to tell me whether there is

Hello all, I want to the do followings: (1) Modify the LLVM front-end(clang) to support EFI C (2) Add EFI Byte Code target to LLVM I am wondering to know which task should I do first, modify front end or porting LLVM? thanks yi-hong -------------- next part -------------- An HTML attachment was scrubbed...

Hello all, I am at the adding Instruction Set stage of adding new target support into LLVM. There is a single instruction op mnemonic with multiple operand forms. For example: Add R1, R2 & Add @R1, R2. I found that there is similar case in x86 instruction set, such like ADD reg, reg & ADD mem, reg. However, the solution of x86 is adding suffix of instruction and translating instruction op

I have this same problem in our backend. I solve it by adding a pseudo instruction at instruction selection that transforms @R1 into R1, so only a single pattern is required. I then can propogate the pseudo instruction after instruction selection.

Hello all, I am a beginner of LLVM and want to add a new Target for LLVM. I follow the document (http://llvm.org/docs/WritingAnLLVMBackend.html) to modify autotools/configure.ac. However when I type ./AutoRegen.sh There is an error that "Your autoconf was not detected as being 2.60" I download the source of autoconf 2.60 and install it. And there is the other error that "Your

Hello all, I am using LLVM/Clang 3.5 to build a C++ extension. Such C++ extension contains a special function named "barrier", which shouldn't be duplicated. So I add __attribute__((noduplicate)) on barrier declaration. For some reasons, I also add AlwaysInlineAttr attribute on each function except main function. The generated LLVM IR what I expect is only a main function with many

Hello all, I download the src of llvm 2.8 and run ./autoconf/AutoRegen.sh However there is a little difference between origin configure file and the generated one $diff configure configure.bak 1394c1394 < --enable-optimized Compile with optimizations enabled (default is YES) --- > --enable-optimized Compile with optimizations enabled (default is NO) I am wondering to know

Hello all, I have some question about usage of TableGen when adding a new LLVM Backend. There are three place to use TableGen in basic steps of document "Writing an LLVM Compiler Backend": 2. Describe the register set of the target. Use "TableGen" to generate code for register definition, register aliases, and register classes from a target-specific RegisterInfo.td input

Hello, I recently try to modify the front end of LLVM for a variation of C. The main difference between the variation and the original one is that I wish to view the "size of" as a function. Would anybody suggest me how to start doing?? thanks yi-hong -------------- next part -------------- An HTML attachment was scrubbed... URL:

Dear Folks, With Samba 3.0.0 RC1, openldap-2.1.22, with samba as PDC and as much as possible in LDAP, do I need to write an add user script and an add machine script? Or does samba handle this itself? Sorry, I'm rather confused about how to go about setting this all up. -- Nick Urbanik RHCE nicku(at)vtc.edu.hk Dept. of Information & Communications

Hello all, I am a LLVM newer who want to add a new backend(EBC) into LLVM. After coping the related files from another target and modifying it, I meet a problem when I build the project. The error message is as follows: ================================================================ [ 94%] Built target llvm-dis Linking CXX executable ../../bin/llvm-mc Undefined symbols:

After a hiatus on the CellSPU development, I've got all of the instructions necessary to get the llvm-gcc frontend to build. I've now discovered a new and interesting problem that I'm not sure how to solve cleanly and it's due to the fact that CellSPU has no fixed size condition flags. CellSPU's condition flags depend on the size of what's being compared, i.e., if both

Dear team, If I use sambaSamAccount with samba 3.0.0 RC1, do I need to define an add machine script? I want to be able to add machines to the domain as simply as possible (i.e., "automatically"). So is an add machine script needed, or does samba contain code to create the accounts itself? -- Nick Urbanik RHCE nicku(at)vtc.edu.hk Dept. of Information
