Hey everyone..

I was trying to build the jvm on Linux. I=C2=B4m using SUSE Linux and =
GCC 4.=20
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:=20

class.c: In function =E2=80=98class_load_resolve_clinit=E2=80=99:
class.c:1631: error: invalid lvalue in assignment


which is a Macro=20

 PUSH_FRAME(thridx, pca->max_locals);=20

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

(pjvm->thread[thridx].sp) +=3D ((pca->max_locals));
(pjvm->thread[thridx].sp) +=3D (1);
 pjvm->thread[thridx].stack[pjvm->thread[thridx].sp - 0] =3D (jint) =
(((pca->max_locals)));
(pjvm->thread[thridx].sp) +=3D (1);
 (rvoid *) *(&(pjvm->thread[thridx].stack[((pjvm->thread[thridx].sp) - =
(1 +1))])) =3D GC_STACK_NEW(thridx, (pca->max_locals));
(pjvm->thread[thridx].sp) +=3D (1);=20
pjvm->thread[thridx].stack[pjvm->thread[thridx].sp - 0] =3D (jint) =
((pjvm->thread[thridx].fp));
pjvm->thread[thridx].fp =3D (((pjvm->thread[thridx].sp) - ((1 + 1 + =
1))));
(pjvm->thread[thridx].sp) +=3D (1);
 pjvm->thread[thridx].stack[pjvm->thread[thridx].sp - 0] =3D (jint) =
((pjvm->thread[thridx].pc.offset));
 (pjvm->thread[thridx].sp) +=3D (1);
 pjvm->thread[thridx].stack[pjvm->thread[thridx].sp - 0] =3D (jint) =
((pjvm->thread[thridx].pc.excpatridx));
 (pjvm->thread[thridx].sp) +=3D (1);
 pjvm->thread[thridx].stack[pjvm->thread[thridx].sp - 0] =3D (jint) =
((pjvm->thread[thridx].pc.codeatridx));
 (pjvm->thread[thridx].sp) +=3D (1);
 pjvm->thread[thridx].stack[pjvm->thread[thridx].sp - 0] =3D (jint) =
((pjvm->thread[thridx].pc.mthidx));
 (pjvm->thread[thridx].sp) +=3D (1);=20
pjvm->thread[thridx].stack[pjvm->thread[thridx].sp - 0] =3D (jint) =
((pjvm->thread[thridx].pc.clsidx));;;

I tried putting brackets in various macros but nothing helped.

Any help would be greatly appreciated.

Best Regards,
Sanket Sharma
