Is there a problem if the string is not null terminated? If not, you can snprintf it right into place instead of doing sprintf+mempcy.

Hi, Recently I was hit by an assert in WinCOFFObjectWriter that had forbidden storing pointer to string table in header name field when the pointer had more that 6 decimal digits. This limit had been chosen to make implementation easier (sprintf adds null character at the end) and could be increased to 7 digits. My patch is attached. The implementation uses additional buffer on the stack to make

I've been meaning to cut down on the number of these because they are super slow and wasteful. Some of them are

Hello, As part of a MSIL (i.e. C#) to LLVM frontend I am currently working on ( https://github.com/xen2/SharpLang ), I would need some help/hint about how to properly design "PInvoke callbacks". Through "PInvoke" mechanism .NET allows you to call C functions, i.e.: C#: [DllImport("libc.so")] extern void mempcy(void* dest, void* src, int size); // declaration of C
