           Summary: Webkit can't be built with GCC
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Windows 7
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: lrn1986 at gmail.com

WebKit needs an engine to execute JS. Two are available - LLInt and JIT.

JIT can be built on Windows, but only with MS VC compiler (has inline assembly code that is GCC-incompatible).
When building with JIT, ld complains about undefined symbols callToNativeFunction and callToJavaScript.

LLInt can't be built on Windows, GCC complains:

../webkitgtk-2.4.0/Source/JavaScriptCore/llint/LLIntOpcode.h:59:11: error: label 'llint_throw_from_slow_path_trampoline' used but not defined
     macro(llint_throw_from_slow_path_trampoline, 1) \

This, i guess, is because LLIntAssembly.h can't be generated, the asm.rb script complains:
offlineasm: No magic values found. Skipping assembly file generation.

With neither engines being available, it's impossible to build WebKit.

This affects WebKitGTK-2.3.x (confirmed with 2.3.90) and 2.4.0.
WebKitGTK-2.2.5 builds (2.2.6 is said to be buildable as well, but i haven't tried it yet).
