similar to: [LLVMdev] How to build an LLVM pass through visual studio

I found that LLVM optimized the IR by replacing printf with puts. I wondered which pass did this optimization? And is it common that puts is faster (and some other metric) than printf? -- Thanks Thomson -------------- next part -------------- An HTML attachment was scrubbed...

Could generated assembly with option "-x86-asm-symtab=intel" be assembled by nasm directly?

I saw many definitions derived from Instruction defines OutputOperandList and InputOperandList (usually in the xxxInstrFormats.td), but I don't see where they are referenced. Anything I missed here?

I saw some LLVM generated assembly in NASM format, but did find this support in the official release. Is this supported? -- Thanks Thomson Tan -------------- next part -------------- An HTML attachment was scrubbed...

I just found that some samples used link.exe from Visual Studio to generate the final image, does LLVM has a replacement for link.exe to generate the final binary? -- Thanks Thomson -------------- next part -------------- An HTML attachment was scrubbed...

I saw there is reference to dead def on registers in LLVM source code. I am not aware of this concept from the traditional course material. What are the properties of dead def?

The blow snippet in target.td shows the regList in RegisterClass is typed as dag. Why not make it a simple list, such as list<Register>? class RegisterClass<string namespace, list<ValueType> regTypes, int alignment, dag regList> Thanks, -Thomson -------------- next part -------------- An HTML attachment was scrubbed...

To generate code for a target which doesn't have immediate constant as instruction operand, do I (the target specific back-end, XXXTarget) need to provide code to break up the SDNode with constant (like ISD::ADD $reg1, #1) to 2 SDNodes (ISD::LOAD $reg2, #1; ISD::ADD $reg1, $reg2) in my XXXTargetLowering::LowerOperation, or LLVM target-independent framework can do such transformation

Is there any reason why link.exe is undesirable? You can

If by "NASM format" you mean Intel syntax, then yes. In my experience most LLVM tools refer to it with the option "-x86-asm-syntax=intel". For example, tools/llvm-objdump has this flag. --Sean Silva On Wed, Jun 20, 2012 at 10:12 PM, Thomson <lilotom at gmail.com> wrote: > I saw some LLVM generated assembly in NASM format, but did find this > support in the

Hey chenwj, Thanks for the reply.Actually, I tried Cygwin to get things work on windows.Any idea how does it compare with MinGW?

hi, i am wondering if this link is still updated? http://www.llvm.org/docs/CMake.html#developing-llvm-pass-out-of-source i follow the instruction from the link, and create in my ~/test/ directory the CMakeLists.txt with following content: $cat test/CMakeLists.txt find_package(LLVM) # Define add_llvm_* macro's. include(AddLLVM) add_definitions(${LLVM_DEFINITIONS})

Thanks, John. This sounds reasonable that the analysis group just provides an interface to its implementors (pass). Then I have another question, is it allowed to specify multiple pass in the same analysis group in the command line for opt? If yes, which pass will be used for the call of getAnaysis<AnalysisGroup>()? -Thomson On Mon, Jun 25, 2012 at 10:34 PM, John Criswell <criswell at

Using multiple analysis passes that belong to the same group may

Hi! I was trying to run an already build LLVM-pass ( the Hello world ) on Visual Studio. I could locate the The Hello world pass sources in llvm/lib/Transform/Hello/*.But when I compiled llvm using the command "cmake -G "Visual Studio 10" ..\llvm" , I couldn't find the LLVMHello.so file in "build_directory/Debug/lib/LLVMHello.so" neither in

Hy all of you, I've successfully installed a freepbx solution with 10 extensions : - 5 on Linksys SPA922 - 1 on Linksys SPA942 - 1 on Thomson ST022 Everything seems to work fine with all the hardphones excepts last week. The thomson has a strange behaviour. It can reach french mobile cell phones but when it reaches "fix" phones, the correspondant can't hear the caller. What
