In the documentation at http://haxe.org/manual/lf-condition-compilation-flags.html it is specified that a DCE log can be displayed when the -dce-debug compiler flag has been specified.

However, when I specify this flag, the Haxe compiler fails with:

Error: : unknown option `-dce-debug'.
Haxe Compiler 3.2.0 - (C)2005-2015 Haxe Foundation
Usage : haxe.exe -main <class> [-swf|-js|-neko|-php|-cpp|-as3] <output> [options]

How can I see the DCE log? I want to find out why certain classes are eliminated and others are not.

Thanks,
Seb

p.s. also tried --dce-debug without luck.

How about:
-D dce-debug
?

Works :-)

However it is confusing that some of the flags can be specified directly, e.g. -dce or -macro whereas others like dce-debug need to be specified via -D dce-debug

The page doesn't really mention this.

Thanks,
Seb

The page you linked to is about built-in "conditional compilation flags".

The page starts with a link to the definition and usage of such flags.

-dce and --macro (not -macro) are haxe command line arguments, run:
haxe --help
-dce just happens to set a compiler flag, it's a shortcut for -D dce=mode
--macro does something quite different
-D <var[=value]> is also a command line argument, that can set any compilation
flag (also your own)

haxe --help-defines
lists all compiler flags
