After double-checking what these flags actually do, I'm going to add some more information to the commit description: ``` The `/Zc:inline` flag tells the compiler to generate object files but exclude symbols that are either unreferenced or have internal linkage only. This leads to smaller object files and faster linking. See: https://msdn.microsoft.com/en-us/library/dn642448.aspx The `/debug:FASTLINK` flag changes how the linker generates program database files (PDB). Instead of making a full copy of any related debug information used by the library, this option instead creates indexes to other PDBs, thereby cutting down on link-time code generation. This only affects DEBUG builds. See: https://msdn.microsoft.com/en-us/library/xe4t6fc1.aspx ``` - Joseph Wu On March 28, 2017, 5:55 p.m., Jeff Coffler wrote: > > --- > This is an automatically generated e-mail.

Review Request 58013: WIN32: Add compile/link flags to improve incremental link times.
--- This is an automatically generated e-mail. To reply, visit: https://reviews.apache.org/r/58013/ --- Review request for mesos, Andrew Schwartzmeyer, John Kordich, Joseph Wu, and Li Li. Bugs: MESOS-7226 https://issues.apache.org/jira/browse/MESOS-7226 Repository: mesos Description --- When working on precompiled headers, we recognized that adding some compile/link flags resulted in a 20% reduction in incremental linkage time. This is NOT directly dependent on precompiled headers (the improvement comes regardless of PCH).
