[Mesa3d-dev] Normal initialization problem on VMS-Alpha solved?

[<jo...@du...>]

Hi All,

I finally found the problem on my VMS/Alpha system when running some of
the modes of xlockmore. It appered that the Normal field of the Immediate IM
in VB.C contained rubish after allocation of the immediate. I propose the
following patch to vb.c (Not yet committed since I want your comments first)

*** vb.c;2      Fri Apr 28 16:06:10 2000
--- vb.c;1      Fri Apr 14 07:43:16 2000
***************
*** 272,279 ****
     IM->Start = VB_START;
     IM->Material = 0;
     IM->MaterialMask = 0;
-    for (j=0; j<VB_SIZE ; j++ )
-      IM->Normal[j][0] = IM->Normal[j][1] = IM->Normal[j][2] = 0.0;

     if (MESA_VERBOSE&VERBOSE_IMMEDIATE)
        fprintf(stderr, "alloc immediate %d\n", id);
--- 272,277 ----


Maybe the same problem occurs on True64(DECUnix/OSF) on Alpha. Since in
principle the same compiler (but for another OS) is used.
Questions:
  -Should I commit this fix for all systems or should I #ifdef VMS it?
  -What about the other data-fields in the Immediate. Can they be corrupt too?
