Bug 172230 – [Win][CMake] Move MSVC compiler options to a common location

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Don Olmstead]

Currently all the MSVC definitions are in OptionsWin.cmake. This means they aren't available for different ports such as JSCOnly.

This moves the MSVC options from OptionsWin over to OptionsCommon.

This is work towards enabling JSCOnly builds on windows.

There is no way to use MSVC on a non-Windows platform.  I see no reason to move this from a Windows-specific file to a file that's used on Linux and Mac.

Would you prefer compiler options in their own files? Like a OptionsMSVC.cmake?

I'm trying to consolidate the options so they can be used to build JSCOnly on Windows. As it is JSCOnly does not build on Windows at all.

OptionsMSVC.cmake would be better than OptionsCommon.cmake

Moving MSVC options to a new file as requested.

[Konstantin Tokarev]

I would prefer if the following options were not moved to OptionsMSVC.cmake: /Zi for release builds, disabling RTTI (GR-), using MT runtime instead of MD or MDd. 

Rationale is that this options are not universally suitable, and it's not possible to revert their effect for downstream port, without duplicating or patching OptionsMSVC.cmake (I'm speaking for Qt port now). Also, there was a proposal in the mailing list to make WinCairo using MD runtime, I think it would be wise thing to do.

I also don't think that JSCOnly should use this options.

OTOH, I would suggest moving "INCREMENTAL:NO" code from Source/WebKit/PlatformWin.cmake to OptionsMSVC.cmake, because large linking times affects pretty much any WebKit port if MSVC is used, and these options should affect binaries built in Tools too.

I agree. This was just a blind copy and I was going to clean up this file in a later patch.

Looks good.  Let's let EWS succeed first
