101528 - [PATCH] linux-m68k compilation and gcc-3 fixes

Status: VERIFIED FIXED

(Core :: XPConnect, defect)

Description

[Richard Z.]

mozilla doesn't compile without this patches ( I hope I will manage to
attach the patch somehow, otherwise available per email )

Works fine even if slightly slow compiled with gcc-3.0.1

Regards
Richard

Why is removing |static| needed?

Comment 3

[David Bradley]

I was wondering that as well as the additional space before extern "C"

Comment 4

[Richard Z.]

the extra space was my error, hope this compile log 

helps answer your other question:

Comment 5

[David Bradley]

Doh! I didn't even consider the extern "C". I'm surprised the compiler didn't
scream about that one.

Comment 6

[Richard Z.]

the way PrepareAndDispatch  is called in the m68k asm code we need

the unmangled name, extern "C" is one way to get it.

r=dbaron, except for the extra indents here:

and here:

If someone, shaver?, can give an sr to this bug I'll take care of checking it
in. I don't have anyway of verifying it though.

sr=shaver, once dbaron's nits are fixed.

Attachment: Reformated patch with dbaron's changes

I noticed that the security/coreconf/linux.mk file is branched. Does anyone
know if I should check this in on the TNSS_CLIENT_TAG branch as well as the
tip?

[David Bradley]

Patch checked in
