This flag allows specifying the threshold size for placing static data in large data sections when using the medium code model on x86-64. When using -Ccode-model=medium, data smaller than this threshold uses RIP-relative addressing (32-bit offsets), while larger data uses absolute 64-bit addressing. This allows the compiler to generate more efficient code for smaller data while still supporting data larger than 2GB. This mirrors the -mlarge-data-threshold flag available in GCC and Clang. The default threshold is 65536 bytes (64KB) if not specified, matching LLVM's default behavior. |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
