<DIV><SPAN class=390141315-08062005> <FONT face=Arial size=2>I
was inspired by the Quest tool and decided to give it a try on LLVM. It
quickly located two bugs which appear to be in the bug database
already:</FONT></SPAN></DIV>
<DIV><SPAN class=390141315-08062005><FONT face=Arial

<DIV><SPAN class=390141315-08062005><FONT face=Arial size=2>Bug #279 - <!--StartFragment --><FONT face="Times New Roman" size=3> <TD
valign="middle"></TD><TD valign="middle" align="left">[llvmgcc] "constructor"
code generation can be
improved</TD><!--StartFragment --></FONT></FONT></SPAN></DIV>
<DIV><SPAN class=390141315-08062005></SPAN> </DIV>
<DIV><SPAN class=390141315-08062005> <FONT face=Arial
size=2>Although, the code that Quest generates actually *crashes* LLVM instead
of producing poor output. Should this be added as a separate bug, or just
annotate the existing one?</FONT></SPAN></DIV>

<DIV><SPAN class=390141315-08062005><FONT face=Arial size=2>Bug #323 <!--StartFragment --><FONT face="Times New Roman" size=3> <TD
valign="middle"></TD><TD valign="middle" align="left">[llvm-gcc] crashes on
union with bitfield</TD> </FONT></FONT></SPAN></DIV>
<DIV><SPAN class=390141315-08062005></SPAN> </DIV>
<DIV><SPAN class=390141315-08062005> <FONT face=Arial
size=2>This one pops up quickly when -O3 is turned on. Nothing new
compared to the existing bug.</FONT></SPAN></DIV>
<DIV><SPAN class=390141315-08062005><FONT face=Arial

<DIV><SPAN class=390141315-08062005> <FONT face=Arial
size=2>Since Quest hit these two bugs so frequently, I had to re-arrange the
test generation suite to work around them. Attached is the new ANSI test
suite; simplified to remove floats, doubles, long longs, bitfields, and includes
a work-around for the constructor bug.</FONT></SPAN></DIV>

<DIV><SPAN class=390141315-08062005> <FONT face=Arial
size=2>Also attached is the auto-test script that I've been running. It's
been running for 24 hours with no problems (about 200,000 test
cases).</FONT></SPAN></DIV>

for someone,</FONT></SPAN></DIV>
