<p><font face="Courier New, Courier, monospace">Hi all,</font></p>
<p><font face="Courier New, Courier, monospace">I'm working on
finding(generating) programs which results in bad codegen when
(-g, !-g) option. As suggested in llvm-dev list I tried
diffing the disassembly of object files .text section with -g
enabled and not enabled for all SingleSource unittests .c
files, I used all optimization levels [0,1,2,3,s,z] but I
didn't get any bad codegen behavior.</font></p>
<p><font face="Courier New, Courier, monospace">And then, I used
csmith tool to randomly generate .cpp files and compile them
with (-g, !-g) at various opt levels, after trying for 3 hours
I can only able to produce 2 bad codegen behaviors. Is there
any way for producing bad codegen behaviors? <br>

<p><font face="Courier New, Courier, monospace">Csmith use many
options to generate code, anyone with csmith experience please
guide me how to make use of those options to fullest in this
case?</font></p>
<p><font face="Courier New, Courier, monospace">Thank you very
much :) <br>
