How to create stub shared libraries on Linux

Let's first explain what I mean with a stub shared library: a shared library that can be used to link against (w/ a certain interface provided by a real library) but don't contain the actual code (so has no functionality). Along with the header…

Weird MIPS assembler behavior with jump (and link) instruction

So, we're studying MIPS architecture at school and we're implementing a MIPS32 architecture. I thought I'd use GNU cross-binutils as assembler but I'm getting weird output when dealing with instructions jal, j and jr. The assembler seems to insert…

I want to know precisely how much object code is generated by GCC for each of a collection of compilation units, but I'm having an odd problem where the "size" command from binutils is not giving the correct result. Let's take a C file containing…

Is there a binutils for llvm?

The LLVM compiler toolchain has a gcc that is compatible with normal gcc. The advantage of using llvm-gcc is that is goes to an arbitrary target, meaning normal gcc will say no such target when you try to compile to a random architecture, say…
