Bug 100756 – [Qt] udis86_itab.c is always regenerated

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Csaba Osztrogonác]

Disassembler build was enabled by http://trac.webkit.org/changeset/132606,
but udis86_itab.c is always regenerated.

The root of the problem is that the generator script - disassembler/udis86/itab.py doesn't accept 
output directory as parameter and always generates udis86_itab.c and .h into the actual directory, 
which is WebKitBuild/Release/Source/JavaScriptCore. But all other generated sources are generated 
into WebKitBuild/Release/Source/JavaScriptCore/generated. 

The problem is that Tools/qmake/mkspecs/features/default_post.prf automatically adds "generated/"
prefix to all generated sources, except we use output_function of the generator.

Patch is coming soon.

I have to take closer look at the generator-qmake-logic, but shouldnt we be able to add generated/ for a regular output? In any case, do we still need output and outut_function?

1.) Of course we can also add a new command line parameter to the 3rdparty
disassembler/udis86/itab.py ... Let me try it.

2.) I tried to remove the disassembler.output, but TARGET still depends on 
the non-existing udis86_itab.c target for some reason and it causes fail.
(the name of the target is the full path in this case)

Waht do you think about this one? It is bigger, but general fix.
