Bug 79083 – Unnecessary preprocessor macro in MainThread.h/cpp

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Roland Takacs]

Patrick R. Gansterer mentioned at https://bugs.webkit.org/show_bug.cgi?id=73309 that I wrote "#if PLATFORM(WINDOWS)" insted of "#if PLATFORM(WIN)".

I fixed this bug.

IMHO you need an additional line in the exports file too now, when you do not inline the code. But maybe you that, only let the EWS generate the mangeled name... :-)

Sorry, You are right, I meant the other direction.

sorry for not asking earlier, but why can't we simple remove the PLATFORM(WINDOWS)? IMHO nobody needs it.

Please explain why.

You are right, it is really not necessary to check it.

The name was really wrong. I renamed it.

When I changed 'WINDOWS' to 'WIN' and I uploaded the patch, it failed. Secondly, I added the isMainThreadOrGCThreads mangled name to the JavaScriptCore.def, and it works.

I will upload the patch soon without "PLATFORM(WINDOWS)" preprocessor macros.

The ChangeLog should usually explain the what and why. When browsing the history you usually don't look into the bug, so any relevant information should go into ChangeLog. :-)
