<DIV><FONT face=Arial size=2>I hope this is the correct mailbox for problem
reporting.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>my simh vax emulator (3.7-1) fails
while executing mth$gsind under vms 7.0.</FONT></DIV>
<DIV><FONT face=Arial size=2>the debugger identified the failing
code</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>.psect data nowrt,noexe</FONT></DIV>
<DIV><FONT face=Arial size=2>table: .g_floating 0.0, 90.0</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>.psect code nowrt,exe</FONT></DIV>
<DIV><FONT face=Arial size=2>addg3 r0, table[r4], r2</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>the addg3 access to the second operand
(table[r4]) causes an access violation (reason=4).</FONT></DIV>
<DIV><FONT face=Arial size=2>the table is not-writable but the instruction seems
to access it in write mode.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>addg3 r0, table, r2 </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>works without problems.</FONT></DIV>
<DIV><FONT face=Arial size=2>the d_float and h_float variant of mth$sind works
too.</FONT></DIV>
<DIV><FONT face=Arial size=2>the same code works on my real vax (VAXstation
4090) without problems.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Do you have a hint for me where to look for a fix
in the simh-code??</FONT></DIV>
