If I compile a debug build with LDC2, targeting amd64 and without VS installed, does LDC generate debug infos compatible with GDB or not ?

LDC/LLVM generates CodeView for MSVC targets and DWARF for MinGW (...-windows-gnu triples). MinGW isn't fully supported though, so unless GDB supports CodeView in the meantime, it probably won't work.

sounds like what I want, I'll try this.
So in theory when MS toolchain is not installed, LDC uses the MinGW libs, so this path should be taken as well.

Nope, it uses the MinGW-*based* libs, where all regular MinGW extensions/overrides of the underlying MS C runtime have been patched out. They cannot be used for ...-windows-gnu targets.
