r=me. Is there something we might be able to add to the style checker to enforce these rules, at least for JSC?

I hope so!  Btw, this would have to be a JSC-only rule.  In WebCore, Operations.h is included by JSBindings.h or something so that you don't have to include it everywhere.  That's fine since none of JSC's *Inlines.h would ever include any WebCore headers.

More stuff.  Same basic idea as the last patch.

No, these aren't real errors.  EFL is using -Wundefined-inline.  I think it's a good warning flag, and clang added it sometime recently so clang-based builds might end up using it, too.  To make this flag work, files should never unconditionally include the cpp module's corresponding interface header but then conditionally incl *Inlines.h or Operations.h.  The best way to make this work is to either never conditionally include headers, or to wrap the .cpp file's condition around the whole file excluding config.h.  I think that the latter is more sensible.

You might want to remove the inline keyword from "inline bool isHostFunction() const" (JSFunction.h), like Oliver did in the r163195 odissey (and got rolled out in r163225).

Hmmm.  I kind of like the idea of having that function be inline.  And I like the basic gist of what the warning is trying to do.

To make this flag work, files should never unconditionally include the cpp module's corresponding interface header but then conditionally incl *Inlines.h or Operations.h.  The best way to make this work is to either never conditionally include headers, or to wrap the .cpp file's condition around the whole file excluding config.h.  I think that the latter is more sensible.

It would still be marked inline in its definition, in Executable.h. Isn't that enough for suggesting the compiler you'd like that function to be inline?

You're right.  But is it clear that we *don't* want this warning?  If we don't want it, then isn't the solution just to remove that warning from the EFL build?

How is this change related to "Never include *Inlines.h files in interface headers, and never include *Inlines.h when you could include Operations.h instead" topic?

It was just obviously wrong code.

Why do we need zillion of this kind of coding style violations?
For example the whole DFGPhase.h is guarded by ENABLE(DFG_JIT).
Why do we need guard it again in this cpp?

EFL build sometimes gets unhappy if you include a header that declares an inline function but fails to include the header that defines it.  Generally, interface headers such as DFGPhase.h may declare inline functions.  Even though that's not the case here, I figured it would be better to have a unified story for this.  In some places we were doing:

#include "config.h"
#include "Blah.h"

#if ENABLE(...)

And in other places we were doing:

#include "config.h"

#if ENABLE(...)

#include "Blah.h"

I just switched all of the code I knew about to using the second style.  That fixed the EFL builds and made everything more consistent.

The question wasn't here if it is obviously wrong or not. It is
unconventional to push random fixes in absolutely unrelated bug
reports without changelog entry, without any comment and with zillion
coding style violation.

I don't think at all if it is the proper way to fix the issue you mentioned.
Let me investigate the real problem. I'm going to find a better fix than
adding more and more coding style violations and many redundant ENABLE
macros.
