Subject bootJVM linux build...
Date Wed, 24 May 2006 21:10:39 GMT
Hey everyone..

I was trying to build the jvm on Linux. I´m using SUSE Linux and GCC 4. 
I am facing a little problem with macro expansion and some help would be greatly appreciated.

While trying to build the jvm, I get the following error: 

class.c: In function ‘class_load_resolve_clinit’:
class.c:1631: error: invalid lvalue in assignment


which is a Macro 

 PUSH_FRAME(thridx, pca->max_locals); 

When I do a gcc - E and save output to file, I can see the macro being expanded to:

(pjvm->thread[thridx].sp) += ((pca->max_locals));
(pjvm->thread[thridx].sp) += (1);
 pjvm->thread[thridx].stack[pjvm->thread[thridx].sp - 0] = (jint) (((pca->max_locals)));
(pjvm->thread[thridx].sp) += (1);
 (rvoid *) *(&(pjvm->thread[thridx].stack[((pjvm->thread[thridx].sp) - (1 +1))]))
= GC_STACK_NEW(thridx, (pca->max_locals));
(pjvm->thread[thridx].sp) += (1); 
pjvm->thread[thridx].stack[pjvm->thread[thridx].sp - 0] = (jint) ((pjvm->thread[thridx].fp));
pjvm->thread[thridx].fp = (((pjvm->thread[thridx].sp) - ((1 + 1 + 1))));
(pjvm->thread[thridx].sp) += (1);
 pjvm->thread[thridx].stack[pjvm->thread[thridx].sp - 0] = (jint) ((pjvm->thread[thridx].pc.offset));
 (pjvm->thread[thridx].sp) += (1);
 pjvm->thread[thridx].stack[pjvm->thread[thridx].sp - 0] = (jint) ((pjvm->thread[thridx].pc.excpatridx));
 (pjvm->thread[thridx].sp) += (1);
 pjvm->thread[thridx].stack[pjvm->thread[thridx].sp - 0] = (jint) ((pjvm->thread[thridx].pc.codeatridx));
 (pjvm->thread[thridx].sp) += (1);
 pjvm->thread[thridx].stack[pjvm->thread[thridx].sp - 0] = (jint) ((pjvm->thread[thridx].pc.mthidx));
 (pjvm->thread[thridx].sp) += (1); 
pjvm->thread[thridx].stack[pjvm->thread[thridx].sp - 0] = (jint) ((pjvm->thread[thridx].pc.clsidx));;;

I tried putting brackets in various macros but nothing helped.

Any help would be greatly appreciated.

Best Regards,
