The MicroBlaze™ processor compilers support the -fPIC switch to generate position independent code. While both these features are supported in the Xilinx compiler, they are not supported by the rest of the libraries and tools, because Vivado only provides a standalone platform. No loader or debugger can interpret relocatable code and perform the correct relocations at runtime. These independent code features are not supported by the Xilinx libraries, startup files, or other tools. Third-party OS vendors could use these features as a standard in their distribution and tools.
