1Internal property sheets: 2 essential.vsprops 3 Contains the common settings used throughout the projects. Is included by either ..\debug.vsprops or ..\release.vsprops, so in general, it is not included directly. 4 5 release_defaults.vsprops 6 Included by ..\release.vsprops. Its settings are overriden by release_impl$(CHROME_BUILD_TYPE).vsprops. Uses the default VS setting which is "Maximize Speed". Results in relatively fast build with reasonable optimization level but without whole program optimization to reduce build time. 7 8 release_impl.vsprops 9 Included by ..\release.vsprops by default when CHROME_BUILD_TYPE is undefined. Includes release_defaults.vsprops. 10 11 release_impl_checksenabled.vsprops 12 Included by ..\release.vsprops when CHROME_BUILD_TYPE=_checksenabled. Matches what release_defaults.vsprops does, but doesn't actually inherit from it as we couldn't quite get that working. The only difference is that _DEBUG is set instead of NDEBUG. Used for keeping debug checks enabled with a build that is fast enough to dogfood with. 13 14 release_impl_official.vsprops 15 Included by ..\release.vsprops when CHROME_BUILD_TYPE=_official. Includes release_defaults.vsprops. Enables Whole Program Optimizations (WPO), which doubles the build time. Results in much more optimized build. Uses "Full Optimization" and "Flavor small code". 16 17 release_impl_pgo_instrument.vsprops 18 Included by ..\release.vsprops when CHROME_BUILD_TYPE=_pgo_instrument. Includes release_defaults.vsprops. Enables Profile Guided Optimization (PGO) instrumentation (first pass). Uses "Full Optimization" and "Flavor small code". 19 20 release_impl_pgo_optimize.vsprops 21 Included by ..\release.vsprops when CHROME_BUILD_TYPE=_pgo_optimize. Includes release_defaults.vsprops. Enables Profile Guided Optimization (PGO) optimization (second pass). Uses "Full Optimization" and "Flavor small code". 22 23 release_impl_purify.vsprops 24 Included by ..\release.vsprops when CHROME_BUILD_TYPE=_purify. Includes release_defaults.vsprops. Disables optimizations. Used with Purify to test without debug tools and without optimization; i.e. NDEBUG is defined but the compiler doesn't optimize the binary. 25
