Yep, and this for the linker cmdline:
https://github.com/ldc-developers/ldc/blob/13cc3c4ed2f4e77096313916e55ce460f9dd1ddc/driver/linker-gcc.cpp#L535-L543

So yes, these are the default settings for Linux targets (the 
linker-strip-dead option is enabled by default), even for debug 
builds. For non-Linux targets, we rely on the LLVM defaults wrt. 
func/data sections; --gc-section is definitely only used for 
Linux targets though (use `-v` in the LDC cmdline to print the 
linker cmdline).
