[Dirk Pranke, 2016/01/28 00:30:49]

is there a matching GYP equivalent for this?

[zhaoqin, 2016/01/28 04:05:02]

no, that was added for building fuzzers on Windows without libfuzzer. All those
fuzzers seem can only build via GN.

+      'gn_args': 'is_component_build=true enable_iterator_debugging=false',

[zhaoqin, 2016/01/27 04:24:15]

actually, I am not sure if enable_iterator_debugging=false really maps to
build_for_tool=drmemory.

I found that mapping from
https://chromium.googlesource.com/chromium/src/+/master/tools/gn/docs/cookboo...

However, according to:
https://code.google.com/p/chromium/codesearch#chromium/src/build/common.gypi&...
build_for_tool=drmemory need tweak several options for running Dr. Memory
properly.

https://code.google.com/p/chromium/codesearch#chromium/src/build/config/BUILD...

enable_iterator_debugging=false probably only handles the
win_debug_disable_iterator_debugging, not other tweaks. 

[Dirk Pranke, 2016/01/28 00:30:48]

Honestly, I have no idea what this will do. I'm happy to let this go through
as-is and we can test things and see if they are being built right, but if you
like we can also try to dig into the actual GN and GYP files and see if this is
right or if we need other things as well.

Acknowledged.
