Re: Need some old docs
It's great to see that there are still some working on OnBoardC. Being an old
school C programmer I thought about refactoring VFSDos, because it seems to
have many flaws. However, time's limited... :-(

It helps a lot to let the GCC compiler generate assembler source code (option
"-S") and to study that.
>From my experiences writing Phoinix (phoinix.sf.net) I'd recommend to try:
__asm__("link %a6,#0\n\t"
"move.l %a6,-(%a7) ; push a6\n\t"
"jbsr setA6_00(%pc) ; no need of add #4,a7\n\t"
"unlk %a6 ; restore stack\n\t"
"rts\n\t");
and
__asm__("jbsr getA6_00(%pc) ; get value in d0\n\t"
"move.l %d0,%a6 ; restore a6\n\t"
"move.w 4(%a7),%d0 ; return value\n\t"
"unlk %a6 ; restore stack \n\t"
"rts\n\t");
respectively. You may also replace "%a7" by "%sp", or "%a6" by "%fp", if you
like it better. The pseudo-op "jbsr" uses "bsr.s", "bsr.w", or "jsr",
whichever is appropriate.
Anyway, I found the complete source, and it looks better to me to use these
lines, provided that your A5 point to the globals. It saves some calls and
returns.
void Tag(void)
{
__asm__("link %a6,#0 ; set up %a6 for exit()\n\t"
"move.l %a6,me...@end.w(%a5) ; store %a6 in global memA6\n\t"
"unlk %a6 ; restore stack\n\t"
"rts\n\t");
}
void exit(int code)
{
__asm__("move.l me...@end.w(%a5),%a6 ; restore %a6 from global memA6\n\t"
"move.w 4(%a7),%d0; return value\n\t"
"unlk %a6 ; restore stack\n\t"
"rts\n\t");
}

Well, the header file contains a prototype with the libref only...

Ryan, Sorry to waste your time with that last stab in the dark. I can't help I'm afraid, I've only ever worked with C on the Palm - never touched assembler.

What I am looking for basically, is porting some old, unsupported code from
OnBoardC Suite to GCC.
The code is Harry Konsta's StdIOLib which is used in his VFSDos and Phillipe
Guillot's PalmPascal Compiler.
http://pages.total.net/~hkonstas/vfsdos.html
I am porting it to GCC to use in the new incarnation of OnBoardC being
worked on by John Wilund and I here: p.sf.net/onboard-ng/main
We are using StdioLib to have plugin<->core communication.
There are certain parts of this code which must be rewritten due to minor
differences in OnBoardC notations and GCC notations. Notably at the moment:
small assembly hacks which works on saving and restoring the A6 register to
global for app start and exit.
void Tag(void)
{
__asm__("link a6,#0\n\t"
"move.l a6,-(a7) ; push a6\n\t"
"jsr setA6_00(pc) ; no need of add #4,a7\n\t"
"unlk a6 \n\t");
}
void exit(int code)
{
__asm__("jsr getA6_00(pc) ; get value in d0 \n\t"
"movea.l d0,a6; restore a6 \n\t"
"move 4(a7),d0; return value\n\t"
"unlk a6 ; restore stack \n\t"
"rts\n\t" );
}
The inline notation itself is legal (changed that already) however, it's the
assembly commands themselves which I am worried about: are those legal
syntax to pass to m68k-palmos-as?
As for my original question:
I am asking for documentation on SysLib* calls because GCC complains about
this call:
// Close StdioLib
if(StdioLibRef!=-1)
{
err=SysLibClose(StdioLibRef,&usecount); // too many arguments to
SysLibClose
if (usecount==0)
{
SysLibRemove(StdioLibRef);
}
}
As I am not sure when to call SysLibRemove without this usecount argument I
am kind of lost as to what to do with it.

RE: Need some old docs
Ryan, Forgive my ignorance, but is it documentation on Palm system functions that you require? There's a section in the companion.pdf that documents these if it's of use to you. Extract below... System Manager This chapter provides reference material for the system manager. The system manager API is declared in the header files FatalAlert.h, SystemMgr.h, and SysUtils.h. For more information on the system manager, see the chapters "Application Startup and Stop" and "Palm System Features" in the Palm OS Programmer's Companion.
