I'm not sure if it is relevant, but... [0] says to use -mtriple to specify CPU and OS because ldc is a cross-compiler, and the tool needs to be told the target. The article then refers the reader to [1]. [1] provides the triples that are recognized. [0] Using LDC, <https://wiki.dlang.org/Using_LDC>. [1] Cross-compiling with LDC, <https://wiki.dlang.org/Cross-compiling_with_LDC>.
