	DustMite	DustMite, is a D source code minimization tool. It's helpful in finding toolchain problems.	Public Domain	Windows/POSIX

To debug D programs you need to use a debugger that understands the format of the debug symbols information that your chosen compiler produces. The quality of the debug symbols information might vary depending on which compiler you use and its underlying debug format. For example, some compiler configurations may present the names of variables and/or functions in it's C mangled form, instead of the natural D name.

Debugging support by compiler

Compiler+Platform	Format	Debugger	Supported functionality
DMD-Win32	OMF	Mago/VisualD	Good support: Breakpoints; Stack frames; Mostly pretty names ('.' shows up as '@'); Variable inspection; Visual Studio based.
		Mago-MI	Good support: Breakpoints; Stack frames; Variable inspection; GDB/MI compatible interface for Mago debugger.
		WinDbg	Supplied with the main D compiler zip file download. Overview
		ddbg	Doesn't seem to be working well. Project no longer maintained.
		OllyDbg 2	Reasonable support when assisted by cv2pdb; stack frames; mangled symbols; shows source code alongside disassembly. Note: v2.01 has a bug that may cause frequent crashes when reading PDB files. Details and patch here.
DMD-Win64 LDC-Win64	COFF	Mago/VisualD	TODO: same level of support as for win32? Has issues with structs and pointers, break on D exceptions can no longer be toggled for unknown reasons.
		RemedyDB	Paid. Works better at certain duties than VS. Still in active development. Does not have an option for break on exceptions, but can be mitigated with putting a breakpoint into an exception CTOR.
DMD-Linux GDC-Linux LDC-Linux GDC-Win32/64	DWARF	GDB	Good support: Breakpoints; Stack frames; Pretty names; Variable inspection;
		ZeroBUGS	"Modular debugger for C/C++/D programming languages (and virtually anything else that supports Stabs/DWARF debug formats)". Supported debugging functionality??
LDC-MinGW	DWARF	-	DWARF debug symbol info seems to be broken for LLVM compiled with MinGW note
DMD-MacOS GDC-MacOS LDC-MacOS	?	GDB	Limited/outdated support? According to Jacob Carlberg: "D symbols need to be prefixed with an extra underscore." "Line numbers don't work."
		LLDB	?
