|  | 1 Internal property sheets: | 
|  | 2   essential.vsprops | 
|  | 3     Contains the common settings used throughout the projects. Is included by ei
    ther ..\debug.vsprops or ..\release.vsprops, so in general, it is not included d
    irectly. | 
|  | 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 witho
    ut whole program optimization to reduce build time. | 
|  | 7 | 
|  | 8   release_impl.vsprops | 
|  | 9     Included by ..\release.vsprops by default when CHROME_BUILD_TYPE is undefine
    d. Includes release_defaults.vsprops. | 
|  | 10 | 
|  | 11   release_impl_checksenabled.vsprops | 
|  | 12     Included by ..\release.vsprops when CHROME_BUILD_TYPE=_checksenabled. Matche
    s 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 inst
    ead of NDEBUG. Used for keeping debug checks enabled with a build that is fast e
    nough to dogfood with. | 
|  | 13 | 
|  | 14   release_impl_official.vsprops | 
|  | 15     Included by ..\release.vsprops when CHROME_BUILD_TYPE=_official. Includes re
    lease_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. Inclu
    des release_defaults.vsprops. Enables Profile Guided Optimization (PGO) instrume
    ntation (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. Include
    s release_defaults.vsprops. Enables Profile Guided Optimization (PGO) optimizati
    on (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 rele
    ase_defaults.vsprops. Disables optimizations. Used with Purify to test without d
    ebug tools and without optimization; i.e. NDEBUG is defined but the compiler doe
    sn't optimize the binary. |
