It adds /LTCG to the linker options, we want to use /LTCG:INCREMENTAL. Right now gyp does not support this option directly, so we add it through additional options.

That's inconsistent with other arguments which looks like <feature> or no<feature>. How about nocctest instead? Or even better - maybe build cctest only if the test argument is specified?

Is there any difference in benchmark results? |

Updated, changed I did run benchmarks over the weekend, comparing node built with vs2017 - "old" using
They seem to pretty much the same, although I'm not an expert in this. |

@nodejs/platform-windows is this something we want to backport to 8.x? Seems like windows tooling for 8.x in general has fallen behind |
|
I'd say backport if it lands smoothly. It's mostly a dev time optimization, IMHO the LTS line can take it or leave it... |

Sets Link Time Code Generation to
INCREMENTAL, improving Release rebuilds speed. The/LTCG:INCREMENTALwas added in VS2015 and is not directly supported ingyp, thus it is implemented withAdditionalOptions. Some more information can be found in this vcblog post.Adds
exe-onlyoption tovcbuild.bat, which will build onlynode.exebinary. It will skip buildingcctest, which takes as long as buildingnode.exeitself.Currently, on my box
vcbuildrebuild takes 8 minutes. With those changesvcbuild exe-onlytakes only 1.5 minute.Ref: #17253
