This flag allows specifying the threshold size above which LLVM should not consider placing small objects in a .sdata or .sbss section. Support is indicated in the target options via the small-data-threshold-support target option, which can indicate either an LLVM argument or an LLVM module flag. To avoid duplicate specifications in a large number of targets, the default value for support is DefaultForArch, which is translated to a concrete value according to the target's architecture.
