[parisc-linux] Need five #defines, please.....

[Christian Suder <csuder@cisco.com>]

Ok,


I'm trying to skin the lizard (mozilla 0.9.7). I can build with the linux
default pthreads, but it doesn' work, windows show up but the content is
not drawn etc.. Hence I'd like to try a build with "classic" NSPR, which
implements it's own threading mechanism. Problem : There is a couple of
hardware-specific definitions that I don't know how to do, but somebody
with some insight in parisc-linux may be able to put it down in 5 minutes
(I hope..). Or maybe it has been solved it already ? 

Here's what I'm missing : 

#elif defined(__hppa__)
/* parisc */    
#define _MD_GET_SP(_t) 
#define _MD_SET_FP(_t, val)
#define _MD_GET_SP_PTR(_t) 
#define _MD_GET_FP_PTR(_t)
#define _MD_SP_TYPE 

As a hint, here some existing defines. As far as my limited incompetence
can tell these provide access to some of the context information of the
threads :

/* Sparc */  
#define _MD_GET_SP(_t) (_t)->md.context[0].__jmpbuf[JB_SP]
#define _MD_SET_FP(_t, val) ((_t)->md.context[0].__jmpbuf[JB_FP] = val)
#define _MD_GET_SP_PTR(_t) &(_MD_GET_SP(_t))
#define _MD_GET_FP_PTR(_t) (&(_t)->md.context[0].__jmpbuf[JB_FP])
#define _MD_SP_TYPE int

/* Alpha based Linux */
#define _MD_GET_SP(_t) (_t)->md.context[0].__jmpbuf[JB_SP]
#define _MD_SET_FP(_t, val)
#define _MD_GET_SP_PTR(_t) &(_MD_GET_SP(_t))
#define _MD_GET_FP_PTR(_t) ((void *) 0)
#define _MD_SP_TYPE long int


/* Intel based Linux */ 
#define _MD_GET_SP(_t) (_t)->md.context[0].__jmpbuf[JB_SP]
#define _MD_SET_FP(_t, val) ((_t)->md.context[0].__jmpbuf[JB_BP] = val)
#define _MD_GET_SP_PTR(_t) &(_MD_GET_SP(_t))                           
#define _MD_GET_FP_PTR(_t) (&(_t)->md.context[0].__jmpbuf[JB_BP])         
     #define _MD_SP_TYPE int
