xptcall Porting Status

What is this?

This is a status page for the multiplatform porting of xptcall. xptcall has a FAQ and a Porting Guide.

This is being maintained by John Bandhauer <jband@netscape.com>. Feel free to email me with questions or to volunteer to contribute xptcall code for any platform.

Status Platform Contributors and ? Possible Contributors Notes
Done Win32 x86 Contributed code! John Bandhauer <jband@netscape.com> win32
Done Linux x86 Contributed code! John Bandhauer <jband@netscape.com> unix (could be better without inline asm overhead)
Done FreeBSD and NetBSD x86 Contributed code! Christoph Toshok <toshok@hungry.com>,
Contributed code! John Bandhauer <jband@netscape.com>		 unix (same as Linux 86 code)
Done BSD/OS x86 Contributed code! Bert Driehuis <bert_driehuis@nl.compuware.com> unix (same as Linux 86 code) Bert contributed patches that *should* do the right thing for all the unixish-x86 versions of this code for GCC 2.7 or 2.8 vs. EGCS 1.1. He notes that the vtbl scheme is different. He is hoping that others will help test the changes using these two compilers on the various platforms where this same code is used. Bert's details
Done Mac PPC Contributed code! Roger Lawrence <rogerl@netscape.com>,
Contributed code! Patrick Beard <beard@netscape.com> 		mac (passing tests and checked in)
Done Solaris Sparc Contributed code! Roger Lawrence <rogerl@netscape.com>,
Contributed code! Chris McAfee <mcafee@netscape.com> 		unix This is checked in and working.
Coded OS/2 Contributed code! John Fairhurst <mjf35@cam.ac.uk> Henry Sobotka <sobotka@axess.com> wrote: This is just to let you know that John Fairhurst's port of xptcinvoke and xptcstubs for our emx+gcc and pgcc builds has been done since March 27th (based on the timestamps of the two *_emx files in my copy of md/os2). While I haven't tested it yet (just started working through build breaks that occur with ENABLE_TESTS on), knowing John, I expect he has. Don't know what the status of the port is for our VAC++ build. John?
Done OpenVMS Alpha Contributed code! Colin R. Blake <colin@theblakes.com> Colin says this is passing all the tests on OpenVMS Alpha!
Done NT Alpha Contributed code! bob meader <bob@guiduck.com> bob writes:
Enclosed is xptcall for alpha/nt target..

It is a variation of the IRIS port (only targeted for win32).

Notice the last 2 files (the change to mozilla\xpcom\build\makefile.win and mozilla\xpcom\build) are needed because I was unable to figure how to do a "declspecexport" from the assembler ASAXP ... if some knows how to do that then those last 2 files won't be needed.

I have had someone look over this code at bridge.com (the entry point to compaq/gem compiler team) and this code was given the OK. I consider it "done".

This code lives in the files where the name includes 'alpha' in the win32 directory.

I will do the Linux Sparc xptcall if nobody else commits to it.

I am attaching a patch which contains my Linux Alpha xptcall code. It passes TestXPTCInvoke and TestXPC on my machine which runs kernel 2.2.7, glibc 2.1.1, and egcs 1.1.2. I have not tested it with older GNU compilers such as gcc 2.8.x. From looking at the Linux x86 code, I gather that the vtable layout is a little different for those compilers and the code will need minor modifications in order to work properly.

I am not sure how much of the code can be used for OpenVMS Alpha and/or Digital UNIX. Currently the code is dependent on the g++ name mangling convention and a few GNU extensions so I'm not sure how useful it will be for the other systems. Hopefully the comments in the code are detailed enough to help people attempting a port.

Working AIX PPC Working Jim Dunn <jdunn@netscape.com> Jim writes:
I have checked in the AIX PPC code for xptcall xpcom/reflect/xptcall/src/md/unix. I have tested it on both the AIX 4.2 & 4.3.2 and TestXPTCInvoke runs on both. I haven't verified is the 'stubs' code is working... I need a test for that... but eventually I will verify.

 Jason has declared this done!
Done BeOS x86 Contributed code! Duncan Wilcox <duncan@be.com>
 unix (yet another reuse of the Linux 86 code!)
Duncan says this is all working. He did the code for old cfront style 'this' adjustment for others to use too!

Note: I've used the symbol (?) to indicate people who have expressed an interest in possibly contributing code. Just because these people are listed here does not mean that they have commited themselves to do the work. If you would like to contribute then let me know. Feel free to email these folks and offer to help or find out what's going on. We're all in this together.
