DW_AT_stmt_list attribute's value is a section offset to the line no info for current compilation unit. If there is only one compilation unit generated per .o file then it is always zero.

Hi all, While implementing debug info for our backend, we've noticed a problem with debug_line section. We believe that the following code is wrong: // DW_AT_stmt_list is a offset of line number information for this // compile unit in debug_line section. It is always zero when only one // compile unit is emitted in one object file. addUInt(Die, dwarf::DW_AT_stmt_list, dwarf::DW_FORM_data4,

Hi All, Since few days I observe weird change. Consider the following C code char array[] = "0123456789"; extern int test(char arr[], int size); int main(void) { return test(array-1, sizeof(array)-1); } using clang frontend i get this: %call = call i32 @test(i8* getelementptr inbounds ([11 x i8]* @array, i32 0, i32 -1), i32 10) ; <i32> [#uses=1] and using LLVM-GCC this: %1 =

Hi,Could someone explain to me how the sign/zero extensions in LLVM work, please? If I understood correctly, the int type in LLVM doesn't keep the information about signedness of an int. So the question is how can I know if instructions like Load or Trunc should be signed or not? I guess that at least ARM backend produces sign extended load so if someone could point me to the code where it

Hi all, while I was playing a little bit with IRBuilder I ended up with something like this when included NoFolder.h /work/llvm/include/llvm/User.h: In member function ‘llvm::Value* llvm::NoFolder::CreateExtractElement(llvm::Constant*, llvm::Constant*) const’: /work/llvm/include/llvm/User.h:48: error: ‘static void* llvm::User::operator new(size_t)’ is private

Hi all Ups, I'm really sorry for that previous message, I've sent it by mistake. So let me write it once more. I've been working for some time now on a backend for our CPU. However I couldn't figure out how to implement some stuff. I'd appreciate your help with these. First thing is return address saving. To do that, first I have to copy it to a general purpose register. I

Hi, After discussion with Anton, I did the whole thing in a little bit different way (please see the attached patch). It again looks like reinvented wheel for LLVM experts, I suppose, but it works. What I want to achieve is to generate real (with all variadic arguments) call signature for each variadic and external function, without the "vararg" keyword and without the "...",

Hi, So for everybody who could be interested in LLVM Camp in Paris - it will be in French. I've just received an email from Eric Mahé.

Hi, Could anyone tell me how can I turn off printing .file directive. I want to make a custom output of the filename. In AsmPrinter::doInitialization() I found: if (MAI->hasSingleParameterDotFile()) { /* Very minimal debug info. It is ignored if we emit actual debug info. If we don't, this at least helps the user find where a function came from. */ O << "\t.file\t\""

Hi, I'm trying to add a target-specific builtin to clang and llvm. I was able to do that for many different "regular" instructions, however I encountered some issues with one specific. The instruction is syscall, which should force the compiler to act the same way as with regular calls (save registers, return address etc), except that this instruction takes just the syscall number as
