The only thing I can think of is that string.h is being #included and has different signatures for memcpy and strncpy. Possibly "char" is not signed on your machine (very unusual) or some of the parameters are declared as "const". Reid.

...iving incorrect results; however, if I disassemble the LLVM bytecode and recompile with GCC, everything works fine. I encountered the following error when running lli with '-force-interpreter' option: "Tried to execute an unknown external function: sbyte * (sbyte *, sbyte *, uint) * strncpy" Strncpy is used as part of my compiler's run-time library, and it was compiled with the C-frontend for LLVM. Looking at the assembly, the function is declared at the top of the file; declare sbyte* %strncpy(sbyte*,sbyte*,uint) ;; __builtin_strncpy And it is called like this: %tmp.12...

The problem is that the code generated by the C backend cannot include any system headers. If the system header were to have a #define (not a rare occuran...

Hi, I have the following instruction in my IR- %call2 = call i8* @strcpy(i8* %1, i8* %2) #2 I intend to change call to strcpy with strncpy. I have included the following code in runOnFunction, so that when it is strcpy's turn to be invoked, strncpy is invoked instead. Assuming I* is the strcpy instruction, CallInst* x=new CallInst::CreateCall3(strncpy,1,2,ConstantInt(16),llvm::Twine("my_strncpy")); ReplaceInstWithInst(...

...Differences include (1) SMBIOS is no longer optional for HVM domU''s. (2) The refactoring I did of hvmloader wasn''t really necessary, so I got rid of it. (3) The patches have been tested on changeset 10671:b20580cf7fc1bfe5119597bb5b576cdd020551d5 (4) The versions of strcpy() and strncpy() I wrote in util.c now behave properly: strncpy() pads the destination string with NULs until its size limit is reached and both strcpy() and strncpy() return the address of the destination string.
