The linker still emits pdb files for dlls and executables. There shouldn't be pdb files for objects.

Hi, While working on shared compilation cache for windows, I noticed I could get a 20% build time improvement with the following in .mozconfig: mk_add_options export COMPILE_PDB_FLAG= mk_add_options export HOST_PDB_FLAG= mk_add_options export MOZ_DEBUG_FLAGS=-Z7 (the downside is a 40% disk space increase of the objdir) This is what is currently used on try, and as far as testing goes, it is good enough for breakpad symbols to have the right data so that crashes in tests can be handled correctly.

Re: People building and debugging Firefox on Windows wanted
So I tried it. My objdir size did increase by 40%. Although I can't confirm any speedups as the build time very much depend on the environment I am building in and the other stuff that I am doing on the box. I will try to so an untouched build in a cooled environment in a couple of days.

Re: People building and debugging Firefox on Windows wanted
My improvements were closer to 5%. I use VS2013's amd64_x86 cross-compiler. I didn't touch the -FS flag (I imagine it just becomes meaningless). Debug build, before: build 17:06, objdir 3.83GB Debug build, -Z7:build 16:06, objdir 5.22GB Opt build, before: build 17:47, objdir 3.01GB Opt build, -Z7: build 16:59, objdir 4.43GB I used the opt Z7 build for a bug investigation and, at least at first glance, I didn't notice any problems with the debugging information.
